The BM series consists of three-phase, asynchronous brake motors totally enclosed fan cooled. The BM series frame size ranges from 56 up to 160.
As standard the brake power supply is DC with a rectifier integrated in the terminal box. The rectifier is provided with an over-voltage and radio frequency emission protection device.
The cooling fan is fitted at non-drive shaft end.
BM series main features are low braking noise, gradual acceleration during the motor start and stop and the reduced overall dimensions
