Parvalux Electro Magnetic (Fail Safe) Stop Brakes

(P1-P6) for Induction Motors

Note: Brakes cannot be fitted to T.E.F.C. units.For frequent stop/starts (more than 3 per minute) please contact our sales engineers.

2 core cable40cm longminimum.

BC

These single-disc electro magnetic brakes are spring applied electrically released units which provide fail to safe operating characteristics, such that on interruption, or failure

of power supply, the brake will engage and arrest the load. These brakes operate from single phase a.c. supply (not P5 or P6) and incorporate a built in rectifier. This offers

the brake a vibration free characteristic through a lower operating voltage spectrum.

CAPACITOR START CAPACITOR RUN MOTORS

Shown is a typical “torque/speed” characteristic for this type of motor, these units are only suitable foroperating from a single phase AC supply and incorporate a permanently connected capacitor.The speed is fairly constant but it should be borne in mind that the starting torque is lower than the full loadoutput usually in the order of 85% of full load.The motor however has the advantage of low starting current and is particularly suited for frequent reversing.Capacitor motors cause no radio or T.V. interference.

(See below for capacitor details).

SHADED POLE MOTORS

Shown is a typical “torque/speed” characteristic for this motor. The speed is reasonably constant but betweenno load and full load the speed variation is greater than the permanent capacitor type.Starting torque is between 50%-80% full load torque with the advantage of low starting current.It is important to note rotation is set and cannot be electrically reversed.This type of motor does not cause radio or T.V. interference.

CAPACITOR START INDUCTION RUN (CENTRIFUGAL SWITCH)

Shown is a typical “torque/speed” characteristic for this type of motor, the speed is fairly constant over the noload to full load range. This unit incorporates an internal centrifugal switch which connects the starting winding,together with an electrolytic type capacitor, in the circuit for a few seconds. This winding and capacitor is onlyshort time rated, the unit is not suitable for driving high inertia loads or frequent start/stops maximumrecommended 20 per hour.The starting current is in the order of 3 x full load current. This type of motor can be electrically reversed, butmust not be reversed whilst running, the motor must be allowed to come to rest.

THREE PHASE MOTORS

Shown is a typical “torque/speed” characteristic for this type of motor and where a 3 phase supply is availablethis motor should be the logical choice.The speed is constant and starting torque is good, in some cases up to 200% full load.It is possible to instantaneously reverse this type of motor whilst running.This type of motor does not cause radio or T.V. interference.

The photograph shows the type of capacitor we arecurrently stocking.But other types may be supplied depending uponavailability.

When two or more capacitors are necessary for operationthen connect the capacitors in parallel.
