BMBM series consist of three phase AC brake motors with twin DC brakes working independently of each other, starting from 71 up
to 200 frame sizes and power range from 0.18 kW up to 37 kW.
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’s 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 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 brake
just using one hand.
The two brakes are supplied through independent rectifiers which are positioned in the terminal box.
Rectifiers are provided with over-voltage protection device and with EMC filter.
It’s possible to have two types of wirings connection to the rectifier for each brake, in relation to the intervention time required.
All BMBM series motors are suitable for inverter use; on request, it’s possible to have the motor with a built-in encoder or to have the
motor ready for the encoder to be easily mounted at customer’s place.
The brake disc friction material is asbestos free and the brake lining has a high friction factor and is long-lasting.
The winding insulation class is F. Class H is available upon request. Motor construction type is Totally Enclosed Not Ventilated, TENV
with IP 54 enclosure rating (IP 55 and external cooling are available upon request).
BMBM series motors tolerate a high overload level and being not self-cooled have to be used on intermittent duty only.
On request it’s possible to provide motors with thermo-protection devices.
Frame is made of die cast, light metal on motors up to 132 frame size and of cast iron on motors from 160 up to 200 frame size.
Feet are frame integrated (they are not simply attached to the frame) on IM B3 mounting (foot mounted) and it makes the motor very
sturdy since this motors are used in critical applications.
Shields and flanges are made of aluminum up to 90 frame size and of cast iron for above sizes.
