2. General 2.1 Fields of application of VIMARC vibrator motors VIMARC vibrator motors are intended and suited to drive: Vibrating conveyor chutes, vibratory feeders, vibrating pipes, screen conveyors, screening machines, spiral conveyors, automatic sorting machines, knock-out grates, vibrating trestles, resonance conveyors, vibrating mills etc. and other vibratory driven equipement. Any other use or application beyond the specified should be deemed an application for purposes other than the intended. No claims will be accepted by VIMARC for any damage resulting there from. Application for the purpose intended should also include compliance with the operating manual and, in particular, the inspection and maintenance regulations. For the technical information of our motors, such as type, speed, working torque, centrifugal force and the electrical values, please refer to our catalogue. 2.1.1 Motor arrangement and sense of rotation 1 motor = circular vibration 2 motors in opposite direction = linear vibration 2 motors in the same direction = torsional vibration


2.2. Short description of motor structure Completely closed vibration-stiff cast housing with wide feet and cast-on ribs to transmit the centrifugal forces; cast-on suspension eyes are arranged in the centre of gravity of the vibrator motors for easy and dangerless installation in order to be able to attach the motor in any position. The stator with the winding are shrunk in the housing. The sturdy cylindrical roller bearings are pressed into the solid bearing housing which are arranged at both sides. They are permanently lubricated and work completely maintenance-free*. The precisely dimensioned shaft with the shrunk-on rotor runs in the cylindrical roller bearings. The shaft opening is sealed by grease grooves and V rings. Centrifugal weights to generate the centrifugal forces are arranged at the shaft ends at both sides. The vibrator motor is closed tightly by two hood guards (end covers) and round cord silicon rings to prevent dust and moisture from entering. The terminal box is arranged on the stator housing and is closed tightly by a terminal box cover. *Except motors with re-lubrication see chapter 10.4

Vimarc Vibratormotor Type DX (Z)


3. Safety Regulations

The vibrator motor shall be started only, if mounted for the defined use with the corresponding machine and all protection devices.

Attention: In case of handling or work with the vibrator motor the centrifugal weights of the vibrator motor may rotate unexpectedly. Risk of injury or bruising.

• Overall protection of persons is ensured only if the vibrator motors are closed completely • The vibrator motor shall not be used without hood guards at the centrifugal weights.

• The electrical connection of the vibrator motor shall be fused appropriately.

• A damaged insulation of the connection cable and a missing covering of the terminal box

may result in danger to life due to electrical shock! Eliminate such defects immediately. • Explosion proof vibrator motors only shall be used in areas subject to explosion hazard;

they are identified by the type of explosion protection indicated at the nameplate and the Ex symbol at the housing of the vibrator motor.

• Carry out any maintenance or setting work at the vibrator motor only with the machine at

standstill. Prior to the beginning of such work make sure that it is not possible to switch on the vibrator motor by error or unauthorised persons.


4. Transport

In order to avoid risks of personal injury and damage to the vibrator motor, particular care must be taken when moving or transporting the vibrator motor. In addition to the following notes, follow the locally applicable safety regulations and accident prevention regulations • When transporting the vibrator motor on a pallet, secure it against tilting.

• Proper use of transport and lifting tackles shall be ensured.

• Use a minimal of two cast-on suspension eyes to lift or suspend the

vibrator motor. Ropes, shackles, etc. should be fixed at these suspension eyes only.

• The lifting tackles should be certified, undamaged and suitable for

transport and lifting. • Do not mount an additional weight at the motor because the crane hook are designed only

for the dead weight of the motor. • The lifting tackles to lift the vibrator motor should have a rated load-carrying capacity of

two times the weight of the vibrator motor for safety reasons. • Motors may not be stacked, because the standard package used to ship motors cannot

support such weight. • The vibrator motor should be placed down only on its feet.

• Report any transport damage to the manufacturer. Check the undamaged state of the

supporting areas and protective hood guards (end covers). Do not suspend the vibrator motor at the hoods or centrifugal weights. Excessive jerks or dropping down of the motor will result in damage to the bearings and reduce the lifetime cycle of the motor. Do not use such a pre-damaged machine.


5. Storage

VIMARC vibrator motors should be stored according to the following specification until mounted finally: • In enclosed dry rooms

• At a maximum ambient temperature to 40 °C

• Free from vibration to avoid bearing damage

If the vibrator motor must be stored in the open, cover it by tarpaulins (open at the bottom) to protect it from moisture. Provide the covering so that condensation water, if any, can flow off. Place the vibrator motor on suitable supports or in shelves to prevent effects of soil moisture. If seaworthy packed, do not open or damage this packaging of the vibrator motor during transport or storage. If VIMARC vibrator motors are placed on a machine, we recommend, for long storage, to put the setting of the weights to 0% (see chapter 7). After long storage it is necessary to re-lubricate after the first 100 operating hours instead of 500 operating hours as mentioned in chapter 10.4 Caution: Only place the vibrator motor on its feet (base)!

6. Installation VIMARC vibrator motors are supplied ready for installation. For the installation the following

procedure should be complied with:. • Check the consignment for completeness according to Chapter 6.1 – Unpacking and

checking the scope of supply. • Transport the vibrator motor according to Chapter 4 - Transport – to the place of

installation. • Ensure the dimensional accuracy and the suitability of the place of installation according to

Chapter 6.2 – Installation guidelines • Attachment to the vibration machine according to Chapter 6.3 – Assembly at the place of

installation. • Setting of the centrifugal forces and/or the working torque according to Chapter 7.

• Electrical connection according to Chapter 8; when operating two vibrator motors on one

machine, follow the additional hints given for electrical installation.


Important: Prior to installation clean the base surface of the vibrator motor as well as the mounting surface of the vibration machine from paint, grease and oil.

In general, observe the national and local regulations for the prevention of accidents when installing the vibrator motor.

Caution: The centrifugal weights may rotate suddenly when setting the centrifugal force/working torque. Risk of injury or bruising.

6.1 Unpacking and checking the scope of supply Unpack the vibrator motor and check the contents of shipment according to the shipment

document. Dispose the packing materials according to the local regulations for waste disposal.

6.2 Installation guidelines

The requirement of the mounting surface to which the vibrator motor is attached should be: • Flat, level

• vibration-stiff (rigid)

• free from paint, rust, grease and oil

• and have a plane machined surface


6.3 Assembly at the place of installation

Install the vibrator motor as follows: Follow the installation guidelines of Chapter 6.2 in any case. • Mount the vibrator motor by means of hexagon-heads according to DIN 931 or DIN 933 -

8.8 and self-locking nuts according to DIN 982 or 985 - 8. If metric hardware is unavailable, an equivalent to above should be used. Use the recommended torque specifications from the manufacturer of the hardware. • Use new screws and nuts only to mount the vibrator motor.

• In no case use spring washers or serrated lock washers.

Install in the following sequence: • Align the vibrator motor by means of the cast-on suspension eyes.

• Mount the vibrator motor by means of the number and size of screws specified in the

leaflet or motor data sheet and tighten the screws loosely. • Tighten the screws by means of a torque wrench and in accordance of the torque in chapter

14 table 14.1 • Switch off the motors 15 to 20 minutes after start-up and re-tighten all motor mounting

screws using a torque wrench (Table 14.1, Chapter 14). Repeat this procedure after 2 to 3 hours.

• We recommend checking the mounting screws every 4 to 6 weeks.

Caution: If unsuitable screws and nuts are used, the vibrator motor may become loose and cause serious damage.

Caution: Please note that most of the failures and faults are caused by incorrect or loose screwed connections!

6.4 Replacement of vibrator motors • VIMARC vibrator motors leave the factory with the centrifugal weights positioned at

100%, except overseas shipments; then the motors leave the factory with the weights positioned at 0%; this regarding the axle load.

• When using the vibrator motors in pairs on one machine, use two identical vibrator motors

only. Please contact VIMARC B.V. in any case.

The standard design of vibrator motors is supplied by VIMARC with a 100 % centrifugal force setting. In case of shipment to overseas countries or under severe shipment conditions and/or if requested by the customer, the motors are supplied ex works with another setting of the centrifugal forces. The centrifugal forces can be set as follows to modify the force output: 1) Remove the hood guards (6) from both sides. 2) Loosen the weight screws (32) of the internal centrifugal weights (3) and turn the disks in

the same direction of 100 % (refer to warning note) to the desired position. The outer centrifugal weights (5) are held in position by two weight keys (13). A mark is provided on the outer centrifugal weights. Graduation marks with the corresponding percentages are engraved on a scale on the internal centrifugal weights. Each graduation mark corresponds to a certain percentage of the maximum centrifugal force and/or the working torque.

3) Re-tighten the weight screws (32) of the internal centrifugal weights according the torque in Chapter 14 Table 14.2.


4) Attach the two hood guards(6) and tighten them cross-wise. Make sure that the two round

silicon cord rings (9) for the hood guards contact properly and do not jam. Make sure the o-rings have not been damaged when demounting.

Please note carefully that the internal centrifugal weights have to be set to the same value and/or graduation mark at both sides of the vibrator motors. Unequal setting of the centrifugal weights will generate excessive uncontrolled transverse forces which may result in destruction of the motor and the vibration machine.

In addition, persons standing nearly may be injured or damaged otherwise.

Never operate the motor with a higher RPM shown on the nameplate because this will result in an enormous reduction of the lifetime cycle of the bearings and a premature failure of the bearing or damage to or destruction of the vibration machine or motor.


8. Electrical connection

• The motor shall be connected only by an authorised electrician. • When connecting and operating the motor, follow the local regulations for electrical

equipment. • Ensure the degree of protection IP66 by carefully installing the cable gland.

8.1 Connection Connect the terminal board in the terminal box as a star or delta connection as follows. Example for 230/400 Volts: Delta Connection Star Connection

Observe the following prior to connection:

• The vibrator motor is provided with a star circuit ready for connection. The vibrator motor can also be operated with a delta circuit if the appropriate mains is provided.

• Connect each vibrator motor individually via protective motor switches. • During the acceleration period of the motor (approx. 3 – 7 s), the starting current is

approx. the 6-fold (for AX-GX) or 9-fold (for KX-HX) of the rated current. Thus select appropriate contactors and switches.

• If the vibrator motor is excessively loaded thermally by frequent switching on and/or off or due to the ambient conditions, thermistors should be mounted in the motor to protect the motor.

• When connecting 2 vibrator motors, check them for contra-directional sense of

rotation

Ensure speed regulation by suitable measures so that the maximum speed is not exceeded; otherwise the machine and persons may be put at risk.


8.2 Installation of connection cable

The motor may only be connected by qualified personnel. The motor must be connected according to local and national codes. The connection of the supply cable must be done as follows: 1 The spacer (6) has to be tightened and

screwed into the terminal box. Make sure that the rubber sealing (7) seals properly.

2 Insert the cable through the scamping bracket (1), the inlet trumpet (4) and the ring (5).

3 Tighten the scamping bracket (1) firmly. The rubber inlet trumpet will be squeezed together and seal off the cable entry.

4 Attach the clamping bracket (2) by means of the screws (3). Tighten the screws. Voltage and frequency of the working environment must coincide with the data shown on the nameplate of the motor. Connect the conductors at the terminal board. Please ensure that the motor is connected correctly in a star or delta circuit. Connection of the motor to three-phase current should be grounded. Protect the terminal box against dust and moisture. The sealing faces of the terminal box and the cover must be clean. Connect the vibrator motor via a protective motor switch and thermal relay. Set the protective motor switch to continuous operation according to the rated current data given on the motor’s nameplate. The thread in the terminal box is M25 for the type AX(Z)-GX(Z) and M25 for type KX(Z)-HX(Z). For the installation of connection cable of type KX(Z) and HX(Z) is refer to the operating manual of the supplied cable gland, Chapter 15.

• After connection of the cables, no foreign bodies must remain in the terminal box. Damage and even full destruction of the motor may be the result of short-circuits.

• Carefully install the cables and provide a sufficient reserve (cable loop) in order to prevent

the cable from rubbing during vibration operation

• Use heat resistant rubber-insulated flexible cable for severe mechanical loads only in accordance with VDE0282 part 4 type H07RN – F of A07RN - F or equivalent in accordance the local regulations for electrical equipment .


Connect the motor by means of a safety switch and a thermal safeguard. It is of utmost importance that the thermal safeguard (thermistor) is connected separately in an ATEX tested (approved) circuit (not via a voltage controller). During continuous operation, the current shall not exceed that value which is given at the nameplate.

Grounding The connection of the motor at the mains shall be grounded. 1) in the terminal box 2) by a grounding terminal at the motor foot.


9. Start-up VIMARC vibrator motors are identified by a serial number which is engraved in the nameplate and at the front of the flange at the stator housing. Nameplate:

i

For the electrical data please also refer to the Annex. VIMARC vibrator motors meet the following technical requirements:

• Type of protection IP66 according to EN 60529 • Insulation class F (155°C) according to DIN EN 60034-1 • Serial tropicalised design of insulation • Ambient temperatures for application from -20 °C to +40 °C • Noise and/or noise level <70 dB(A) according to IEC

The maximum admissible surface temperature of the motor is 120 °C according to ATEX. During operation of the motor, the operating temperature shall not exceed 80 °C measured at the surface of the stator housing in order to maintain the required grease lubrication in the bearing and to achieve the maximum lifetime cycle of the bearing

Application of the motor as a self-contained unit is not allowed. A VIMARC vibrator motor is always a firmly mounted component of a machine. This machine has been designed vibration-stiff and separated from the environment by a vibration isolation (e.g. springs, rubber buffers)


10. Replacement of bearings We recommend always replacing both bearings of a motor when replacing the bearings even if one bearing only is defective. A defective bearing will always damage the other bearing, too. The second bearing would fail within a very short period of time. 10.1 Demounting the bearings 10.1.1 For the Models with Ball Bearings

17 Place round silicon cord rings (9) around the flange of the bearing housing (2). 18 Mount hood guards (6).


If several motors are repaired at the same time, make sure not to exchange the components of the individual motors. This is important for the axial clearance.

10.3 Grease

i

Preferably use the following grease grades: A) Shell Alvania RL3 or Esso Unirex N3 for ambient temperatures from -20 °C to

+40 °C B) Refrigeration grease. Fuchs Renolit S 2. This grease should be used only for

special vibrator motors of refrigeration plants at ambient temperatures of max. – 50 °C.
