WEG Brake Motors
WEG brake motors consist of an induction motor coupled to a Lenze brake, forming an integral, compact and robust unit. In WEG brake motors, the frame material is aluminium from 63 to 112 and cast iron from 63 to 160.
The induction motor is totally enclosed with external ventilation, giving the same performance characteristics of the WEG IP55 range of motors.
Spring operated brakes are brakes with two friction surfaces where the braking force is provided by compression springs. When the motor is disconnected from the supply, the coil of the electromagnet is de-energised. This allows pressure to be exerted by the springs to push the armature plate towards the motor and thus cause the brake disc to be compressed between the armature plate and the endshield.
The brake linings are pressed between the friction surfaces of the armature and the endshield, braking the motor until it comes to a stop. In the case of braking, an air gap occurs between the armature plate and the stator. To release the brake, the coil of the stator is excited by means of DC current. The resulting magnetic flux causes the armature plate to be pulled towards the stator. Thus, the rotor is released.
The brake also can be released manually using the hand release. The hand release returns to its base position automatically after operation.
