Three-phase brake motor BMBM series

asynchronouswith DC brakewith no-current failsafe brake

BMBM series includes three-phase asynchronous brake motors with twin DC brakes working independently of each other, starting from 63 up to 315 frame sizes and power range from 0.08 kW up to 132 kW. BMBM series motors are designed for intermittent duty S3 25% (see technical data). BMBMX series electric brake motors for intermittent duty S3 40% are also available. BMBM series main feature is a very high reliability in those lifting applications where there are high demands of safety and silence. For these reasons BMBM series motors are particularly suitable to be used in TV-cine studios and theatre stages. The motor brakes in case of power supply failure. The braking action is always secured through a very quick and precise stop assuring a safe and a prompt stop in case of unintentional power supply failure. The brake torque remains the same in both directions of rotation and the braking action occurs without shaft axial sliding. The brake components and assembly are designed with special features to be noiseless during stops. The manual brake release is made up of two levers (one for each brake) so to avoid unwanted starts. It’s possible to release the brakes just using one hand. The two brakes are supplied through independent rectifiers which are positioned in the terminal box.
