1. General Information

1.1. About this Instruction Manual

This Instruction Manual corresponds to functioning and control of “SILA” Gearless Permanent Magnet Synchronous Machines produced by LANCOR 2000, S.Coop.

This Instruction Manual forms part of the machine and must be kept nearby for reference purposes. All staff members involved in installation, handling, maintenance or repairs of the machine must have read and understood this Instruction Manual. LANCOR 2000, S.Coop. shall not be held responsible for any damages

or malfunctioning caused by failure to follow the indications provided in this Instruction Manual.

1.2. Usage

“SILA” MSYP-160 machine consists of a permanent magnet synchronous motor without gears (Gearless) and it has been specially designed for application in modern elevators as a substitution to a classic gear motor combination.

MSYP-160.25-16

2.3. Machine configuration

"SILA" machine consist of a motor, a brake, a traction sheave and an encoder. A client may choose the inverter used for supplying power and controlling the machine, although LANCOR has tested machines with inverters from Yaskawa, Control Techniques, Vacon and Fuji Electric brands.

Repair of individual parts by the user or an installer are not described in this Instruction Manual. Such repairs should be carried out by the part manufacturer or after contacting LANCOR 2000 for further instructions.

2.4. Motor

Synchronous motor, of robust construction, is equipped with NdFeB permanent magnets with a large intrinsic energy capacity, which deliver the necessary excitation supply to the motor for its correct operation. Power supply and control are carried out through a frequency controller. Machines are designed with FEM (Finite Elements Method), which guarantee low vibrations and noise levels.


2.5. Traction Sheaves

Traction sheaves are made from GG30 cast, from Ø160 to Ø320 mm, with different number of grooves and diameters of standardized steel cable. They transmit the movement, and each one is designed for different loads and speeds. Refer to assembly and dismantling instructions on page 9.

2.6. Brakes

SILA MSYP-160 machine is equipped with a brake with compression springs activated by direct current. The patented multi-polar winding and sequential functioning system they use, make them the perfect solution due to its hight performance and minimum volume. They are certified as a mechanism against upward over-speeding, in accordance with the 95/16/EC directive and EN81-1 + A3.

The brake consists of a multi-polar winding case, and a brake disk, which rotates in conjunction with the shaft by means of a gear. It has asymmetric mobile plates. They act sequentially, which allows a reduction in the noise level and maximum comfort when stopping. The brake of the MSYP-160 machines is manufactured by Alzola, and there are different types, depending on the required brake torque.

Refer to the corresponding instructions for any operations involving brakes.

2.7. Encoder

Encoder is an electronic element which indicates rotor position and motor speed to the frequency controller. It performs a basic and fundamental role in motor functioning, which would not work without it. A wide range of encoders is available on the market, with different output signals, such as absolute, sin/cos, incremental, etc. Lancor has chosen the Absolute type (unless other type requested by the Client), since this type ensures the best motor response. It is placed opposite the sheave, next to the brake. (Pg 12)

3. General safety instructions

3.1. Installation and preventive maintenance of SILA MSYP machines require the services of qualified staff. Staff members must have an in-depth knowledge of elevator installation, assembly and operation and must read and understand this Instruction Manual.

3.2. The Company shall not be held liable for any damages arising from undue handling, which does not comply with EN-81-1 safety regulations on elevator constructions and other applicable regulations, such as UNE-EN ISO 13857.

3.3. Machines are equipped with lifting eyebolts. Depending on the length of the machine, there may be 2 eyebolts or 4 eyebolts. They are designed to lift the weight of the machine for elevating it, until it is placed into a selected location for installations or for transportation. Therefore, no additional weight must be affixed to them. The machine must always be lifted using ALL the existing eyebolts.

3.4. When performing works on the machine, it is necessary to establish a safety area, with barriers, screens and other devices employed to prevent outside individuals from accessing this service.

3.5. When the machine is stopped, no current is supplied from the regulator, and if the brakes are opened, it is possible that an uncontrolled acceleration of the elevator would occur. Therefore, it is advised to short-circuit main clamps with a contactor. The torque produced by the induced currents when turning, will decrease motor revolutions. Such short-circuiting must be carried out when the motor no longer receives the current from the inverter and it must never be done when it still has the current.

3.6. Brakes are safety components and thus they may not be dismantled or disconnected, especially when the machine is operational.

3.7. For thermal protection, the machine is equipped with 3 PTC sensors of 120ºC, embedded in the stator winding, which protect the motor from excessive overheating above magnet demagnetization temperature. If such sensors are activated, the machine will be stopped and placed out of service.


3.8. The machines are equipped with an additional ventilation system, which consists of a Normally Open bi-metal thermocouple of 70ºC, which will close the circuit if such temperature is reached. Its purpose is to activate 2 electric fans (or only one, depending on the machine type), which will cool down the machine. These fans are placed on a metal sheet over the stator, and they blow air from outside towards the stator surface.

4. Transportation and storage

4.1. Transportation

4.1.1. SILA machines are supplied and packaged in accordance with Client specifications.

4.1.2. Machines must be transported in their original packaging. Additional load may not be placed on top of the machines

4.1.3. Avoid excessive vibration and pushing during transportation.

4.1.4. A visual inspection will be performed once the machine is received and unpacked. Upon detection of any transportation-related damages, a claim will be filled out in the presence of the carrier. Damages occurred during transportation are not covered by our guarantee.

4.2. Storage

4.2.1. The machine must be stored in its original package, in a dry area, without any vibrations and protected from adverse weather conditions and dirt until it is installed. It should not be stored for longer than 1 year, and in such a case, the motor must be moved by hand prior to assembly (opening the brakes) in order to verify that there are no strange noises in the bearings.

4.2.2. Avoid extreme cold or heat (storage temperature must be between -20º and 50ºC), as well as frequent temperature fluctuations.

4.2.3. Avoid condensation or excess humidity and conditions of aggressive humidity (i.e. salt humidity).

5. Installation

5.1. Installation verification

5.1.1. SILA machines leave the factory being completely finished, checked, painted and in corresponding packaging. A copy of the Final Test Report is included in the package.

5.1.2. Installation, connection to a power source and placement in operations must only be performed by qualified staff and in accordance with connection schemes and manufacturer instructions.

5.1.3. If a machine has been stored for some time, a maximum of 1 year, insulation resistance of motor

windings and brake coils must be checked with a megohmeter. Obtained value must be greater than 50 MΩ (500 VDC megohmeter). If this value is not reached, parts must be dried in order to remove humidity. To do so, hot air is directed to the motor or brakes as long as it may be necessary in order to verify that the coil is exposed to a temperature >70ºC. After repeated measurement of insulation resistance, obtained value must be by far greater than the indicated one (50 MΩ).

Do not supply power to the motor and brakes with insulation resistance values less than indicated above, otherwise, insulation breakdown may occur, leading to short-circuiting of windings.

5.1.4. It is possible that the brake disk sticks to the braking surface of the motor frame, especially after prolonged storage and it must be freed up. Therefore, supply must be applied to the brake, and a cutter must be placed between the disk and the braking surface, to release it. It if is not released, the brake case must be dismantled and the disk should be hit with a mallet in order to free it up.


5.1.5. Open the brakes, applying voltage to the coil and run the machine in both directions without load, with the inverter. Make sure that the voltage applied to the motor by the inverter is similar in both directions.

5.1.6. Check the nameplate and enclosed documentation to make sure that they coincide and the machine is the one that in fact needs to be installed.

5.1.7. Machines are ready for operations in a machine room or in upper or lower parts of the elevator shaft, as well as in the space between the elevator and the wall, as close to the wall as possible.

5.1.8. The machine must never be assembled on top of the cabin.

5.1.9. During installation, the machine must be attached to a baseplate especially designed for this purpose. It must be attached by four M-16 screws through threaded holes in the motor frames, placing the screws through the lower part.

M16 - 8.8 screw tightening torque: 210 Nm.

5.1.10. The shaft of the machine is of critical importance for correct operations, thus it should not be hit or

be exposed to loads that are not intended for the elevator.

5.1.11. Cables must go up and down in a vertical manner in regard to motor feet and the wrap angle with the sheave must be of at least 150º.

5.1.12. No welding is allowed at the machine, which must not be used as a base table for welding works, since the current may damage the magnets and bearings.

5.1.13. In order to buffer vibrations, rubber absorbers, which will absorb potential vibrations, must be placed between the machine feet and the baseplate prior to placing mounting screws.

5.1.14. If the sheave has more grooves than required for the cables, they must be placed as close as possible to the motor, in order to reduce the load on the bearings and expand their useful life.

Incorrect placement

Correct placement

5.1.15. Supply to the brake the voltage indicated in specifications, check that the brake opens and closes correctly.

5.1.16. Brakes are safety elements, so if chip cutting works are performed next to the machine, it must be protected from the chips and dust.

5.1.17. The brake is attached to the motor support by Hexagonal head screws. These screws are fastened with a corresponding tightening torque.

Screw Torque

M10 36Nm

M12 62Nm

M14 99Nm

5.1.18. The traction sheave is placed at the factory, but apart from a visual inspection, in order to confirm its


correct assembly it is necessary to confirm with a torque wrench that sheave axial fixation screws are tightened. These screws have a lock washer which prevents the screw from turning. Tightening torque M12 8.8: 85 Nm.

5.1.19. If the sheave is placed incorrectly or has some flaws, it has to be dismantled and re-assembled. Therefore, difference must be made between the machine prior to assembly at an installation and already

assembled at an installation:

Dismantling prior to assembly at an installation is easier (see 5.1.21).

5.1.20. If the machine is assembled at the installation, power supply to the machine must be interrupted and necessary measures must be taken in order to avoid a possible re-connection prior to end of the operation. The cabin and the counterweight should be fixed and the sheave should be dismantled as indicated below.

5.1.21. Assembling and dismantling the sheave

Sheave dismantling: Remove cable anti-exit protectors by loosening the screws used to attached them to

the motor frame, and remove the cables. Afterwards, axial fixation screws are loosened and the sheave axial fixation washer is removed. The sheave fits with a cone at the shaft; extract the sheave by using an adequate extractor. Pay attention as to avoid damaging the shaft.

Sheave assembly: Clean the shaft from possible residue, place the shaft key and the new sheave. Using a

plastic mallet (to avoid damage), hit as close to the center and randomly around the entire girth of the sheave. After that, adjust the axial fixation washer and tighten M12 screws to 85Nm by using a torque wrench in order to achieve adequate fastening. Next, bend the anti-swivel washer in order to prevent the screws from loosening up. Lastly place the cables and anti-exit cable protections, adjusting the distance from the sheave to 4 mm.


6. Operations

Never try to run the machine by applying line voltage, since it may cause an electric failure.

6.1. Motor

The general connections diagram is placed inside part of the terminal box cover, as indicated below.

Lancor machines feature other available connection options, such as with a motor cable shielded hose or with a connector, including an option to remove the terminal box, in accordance with Client's specifications.

6.1.1. As shown on the diagram, the microswitches of the brake are factory-equipped with NC contactor usage. NO contactor is not used, although the Client may use it by changing the connection.

6.1.2. Motor power supply cables must be connected to U-V-W terminals, both at the motor and at the inverter, respecting the phase sequence, because otherwise the encoder will emit an erroneous signal and the elevator could be out of control.

6.1.3. Verify proper operation of power supply contactors and their electrical connection.

6.1.4. Motor protectors must be connected correctly and be ready for operations, as well as disposing of a connected earth wire.


6.1.5. Check that connection data corresponds with the data indicated in the nameplate.

6.1.6. Make sure that the assembly and electrical installation have been properly performed.

6.1.7. Remove all foreign items and garbage from the installation location.

6.1.8. Check that PTC thermal protection is ready. To do so, measure its ohmic resistance, which must be between 20 and 250 Ohm.

6.1.9. Check that the bimetallic thermocouple is Normally Open. To do so, check that its resistance reaches MGO values. The power supply for the fan(s) is 24VDC. Positive in terminal VE1 and negative in terminal VE2.

6.2. Brakes

6.2.1. Before carrying out any operations, refer to the instruction manual for corresponding brakes.

6.2.2. Verification of brake opening and closure, as well as the monitoring must be performed by applying the voltage indicated in the instructions through an uninterruptible power supply. These brakes can be equipped with a Manual Brake Release System.

6.2.3. Brakes are monitored by microswitches of two contactors (NO and NC). The microswitches defined by factory are NC, the client can use the NO contact changing the connection. It is necessary to supply voltage between terminals 3 (positive) and 4 (negative). The voltage range is from 5 to 24Vdc. The Output voltage between 3 and 5, and 3 and 6 will be: Full Voltage when the brake is engaged (led ON), and 0V when the brake is released (led OFF).

6.2.4. Brakes must be protected from voltage surges from power switching by using varistors.

6.2.5. Power will be supplied to brakes with the electric current, once they are connected to the motor and all motor and inverter cables are placed.

6.2.6. Brakes are designed for static braking, acting once the speed is reduced to zero. Therefore, dynamic

braking, or brake operating when the motor is rotating, must be reserved for emergency circumstances or for inspection.

6.2.7. Place brake power supply cables according to the voltage and current indicated in instructions.

6.2.8. Power supply to brakes must be 207VDC, thus a rectifier bridge is required. Lancor offers a power

supply kit for the brakes. It is recommended to operate the brakes with two contactors, one at the AC-side

and another at the DC-side. Switch-on always takes place AC-side. Only then is the overexcitation activated.

Switch-OFF

If short switching times are required (e.g. for EMERGENCY STOP operation), please switch DC-side. The AC-side always has to be switched as well in order to activate overexcitation.

If a longer brake engagement time or a quieter switching noise is required, please switch AC-side.

6.3. Encoder

6.3.1. Refer to assembly and dismantling instructions provided on the next page.

6.3.2. In order to avoid interferences with electronic devices, the motor power supply cable must be shielded with ground grid, connected to the ground of the motor and the inverter.

6.3.3. Once the inverter's autotuning process is complete, the encoder must NOT be loosened or moved from its position, otherwise this adjustment will be lost and another autotuning will have to be carried out

(refer to the instructions on the inverter).

6.3.4. Never touch encoder contactors or wire connectors with bare hands, since electrical components may be damaged by electrostatic discharges. If necessary, touch immediately before any grounded conductor. This way, any possible static load will be discharged.

6.5. Operating conditions

The SILA MSYP-160 machine is designed for operating conditions corresponding to regulation EN81-1 on (Elevator motors), correct performance is guaranteed under the following environmental conditions:

• Room temperature between 5 ºC and 40 ºC.

• Maximum relative humidity of 90% at 25 ºC.

• Maximum altitude of 1000 m. over the sea level.

• Dry and lubricant-free transfer cables. Machine operating under values other than those aforementioned may lead to failure. Please check with Lancor's technical department in case of any variations of these values.

6.6. First receipt

The following must be verified before the first placement into operations.

• Installation and connection to a power source were performed correctly.

• Safety devices have been installed.

• All foreign/assembly materials have been removed.

The load corresponds to the information provided in the nameplate.


7. Verification of elevator functionality, start up

7.1. Brakes testing

Prior to carrying out any testing, make sure that the brakes function correctly. To do so, it is recommended to place the car without any load in the middle of the elevator shaft, open the short-circuit contactor at motor terminals and supply voltage to the brakes. The cabin will go up, being pulled by the counterweight and voltage supplied to the brakes will be disconnected, thus allowing to check whether they function correctly and stop the cabin. If the elevator does not stop, the short-circuit contact will be activated again. This test is a dynamic one, that is, the brakes are applied while the motor is turning, and therefore it must only be carried out during inspections or in case of emergency.

7.2. Check "failure of a brake coil"

7.2.1. The objective of this test is to verify whether the brake is capable of bringing the elevator to a stop, despite a failure of one of its coils. To do so, a nominal load will be placed in the elevator's car, and it will be sent down at its normal operating speed. In order to simulate failure of one of the coils, power should be supplied to them independently through the start/stop keys and then cut off the power supply to all coils except for one. The elevator should slow down and stop. If this does not happen, voltage supply shall be removed from this coil, and the short-circuit contactor will be activated at motor terminals for stopping it. THE INSTALLATION MUST BE PLACED OUT OF SERVICE IN ORDER TO CHECK THE BRAKES!

7.2.2. On the general diagram it is shown that power supply to the coils is provided by terminals 1-2. In order to perform the above test, remove the cables from one of the terminals and bring them to the indicated start/stop circuit, perform the test and place them back at the same place. Repeat the same procedure for the next coil.

Lancor shall not be held responsible for poor handling or testing errors.

7.3. Half-load testing

7.3.1. This test is carried out in order to verify the load balance possessed by the installation, since a cabin with a half-load is balanced. In other words, at any point of the installation, depending on the situation of the cabin, it will go up or down only due to the weight of the cables. To do so, place the cabin in the middle of the elevator shaft, open the brakes, maintaining motor terminals short-circuited. If it does not move, the short-circuited contactor of the motor terminals will open up in sufficient time to see if it goes up or down. Once verified, activate the contactor so that the elevator will not move.

7.3.2. Another manner of viewing it is to open the brakes and supply power to the motor and the inverter, up and down, measuring the current in each direction. The difference should not be greater than 10%.

7.4. Overload testing

This is carried out to verify that the brakes are capable of stopping an elevator even with an overload. To do so, 125% of rated load will be placed in the cabin and it will be sent down at the nominal speed, interrupting power supply to the motor and the brake. The elevator should stop due to application of brakes. This test is a dynamic one, since the motor is turning and the brakes are only prepared for static

braking, that is, when the motor is at zero speed. Therefore, it must be carried out as few times as possible due to possible deterioration.

7.5. Emergency evacuation

Emergency evacuation due to power supply failure shall be carried out through electric opening of brakes, unless the machine is equipped with Manual Brake Release System option. The elevator will move


up or down, depending on the load. In order to avoid a possible loss of control upon machine acceleration, motor terminals must be connected in short-circuit, this will make the motor turn at a very slow speed, since it originates at a very significant decelerator torque, which is convenient for rescuing from any close-by door.

7.6. Brake microswitch testing

The brakes are equipped with a microswitch, which consists of two contactors, NO and NC, which change status when the power is supplied to the brake and are used for monitoring, since it allows us to know exactly whether or not the brake has been activated. These contactors must be tested individually, and if the signal is faulty or incorrect, the elevator must be stopped, since this can lead to a power cut. These contactors are labeled on a general diagram and NC signal is placed on the terminal plate. If desired, the Client may change to NO, which is available. (Diagram on Pg. 10)

7.7. How to remove the cabin from wedging.

If the elevator with a nominal load becomes locked during technical testing or while operating, the cabin will be firmly held by the wedge support, impeding its movement. Therefore, it has to be disengaged. This is carried out by pulling the cabin with the machine itself. The maximum motor capacity is around 160-180%. If we need 100% to move the load and this interlocking is requesting more, the motor will not have much additional capacity, which may not be sufficient from releasing the cabin. If the cabin is close to a door, the load can be decreased a little, which will allow the machine to have more capacity for operations. If this is not possible, use a manual hoist for pulling the cables. Therefore, it is recommended to get one and have it available.

These machines are not equipped with a flywheel that can be operated manually, since the impact is direct and gearless, applied force is extremely high. In addition, they are located in the elevator shaft, which is of difficult access.

7.8. Operational failure

7.8.1. High temperature of the machine

The SILA MSYP-160 machine is equipped with PTC K 120º thermal protection with ohmic output. If extended properly, it can stop the machine and avoid deterioration of windings or magnets. In addition it has a bi-metallic thermocouple of K70º with NO contactor for automatic functioning of the ventilators. Firstly, we'd have to analyze the reasons for overheating, as it may occur for different reasons: intense traffic for a long period of time, high room temperature, inverter imbalance and elevator overload, among others. To rectify this, machine ventilation should be improved.

After checking that the fan(s) are working properly it will be necessary to improve elevator shaft ventilation and to check that the inverter parameters are well configured and that the elevator is not overloaded.

7.8.2. The brake does not open

The brake is the most important part of the machine because it is a safety element. Therefore, it must be checked continuously.

There could be various possible reasons for it: first, use a voltmeter to verify that the power supply voltage is the recommended one for the brake. Likewise, check that signal monitoring from microswitches, NO and NC contactors is correct. Check that the brake coil is in perfect condition. To do so, measure the ohmic resistance of the coil with a polymeter, which should be according to the brake instruction manual. If the air gap is too big, the coil would not have sufficient magnetic energy for closing the circuit and the brake will not open. Air gap is measured with a gauge. It must be even and equal to 0.25 mm. If the brake does not work after correcting it, the distance must be gradually increased up to a maximum of 0.5mm. If it still does not work, replace brake disks, since brake lining is worn out.


7.8.3. The brake does not brake

The principal cause is wearing out of brake liners, which leads to changing brake disks. Refer to brake dismantling instructions and contact LANCOR 2000, S.Coop. in order to obtain a new disc.

7.8.4. Noise with brake opening and closure

The brake may generate an unpleasant noise upon opening or closing. To buffer it, check that the air gap is even and adjust it if necessary. Additionally, brakes should always be switched at the AC power supply side, since coil inductance buffers such noise. Alignment of a brake disk with the braking surface is also very important. They must be placed as parallel to each other as possible, the disk has a gear with an axis, a rubber O-ring seal which buffers such noise if it is placed correctly and it is in a good condition.

7.8.5. Motor does not start

There are several possible reasons for this. First, verify that the frequency regulator is working correctly and that there is adequate voltage supplied to the motor. If the motor is started to the first time, check that the motor's and inverter's phases are connected adequately. Another aspect to be checked is whether the brake opens correctly and microswitch monitoring is correct, since the motor will not start if it closed. If after these verifications the motor still does not start, this could be caused by the encoder, which was moved from its original position. Autotuning process will have to be performed again (refer to instructions on inverter for this procedure). If the motor still does not start and inverter's functionality has been confirmed, the encoder should be replaced as it could be causing this problem.

7.8.6. Noises in the motor

If a strange noise is heard upon starting, this may be caused by a defective bearing. In this case, the motor must be dismantled and sent to Lancor 2000 for replacement. It may also be caused by an incorrect

inverter parameters adjustment, so input data must be reviewed in order to avoid errors. If everything is correct, check encoder connections, since it can also be causing noise. Once the encoder is substituted (refer to dismantling instructions), perform autotuning once again and confirm that the noise has disappeared.

8. Assistance and maintenance

8.1. General notes on maintenance

Comply with occupational hazard regulations.

Pay a lot of attention if you hear strange noises in the machine, notice irregular operations or abnormal consumption. Take appropriate action as each one of such issues may cause safety problems in the elevator.

The machine must only be handled by qualified staff with corresponding training. If this requirement is


not met, refrain from dismantling, changing or making adjustment to the machine in the absence of such staff members.

Bearings have permanent lubrication. Lubrication is not necessary since they are already sealed and the existing grease remains available during the entire useful life.

Check brake lining consumption, which should be done with open brakes, that is, with power supplied to them. Therefore, to do so, make sure that the cabin and the counterweight are standing still and mechanically fixed. If it is not very worn out, it may be regulated by adjusting the airgap of the brakes up to its maximum value. After that, they cannot be regulated any further and the lining must be changed.
