MGM BAH-BAHX Series

BA electric brake motors are supplied as standard as BAH series starting from the frame size 225mm up to 315mm and on request starting from the frame size 80 up to 200. BAH series brake motors are proposed in the BAHX version for continuous duty with efficiency class IE2 / IE3 (compliant with EU regulation 2019/1781), alternatively they can be supplied in the BAH ‘Enhanced Power’ version only for intermittent service (S3 60%).

The BAH series brake motors have the same characteristics of the BA-BAX series motors. The difference essentially consists in the casing of the brake assembly designed to give greater strength and protection against the entry of dust and liquids (IP degree). The BAH series motors are supplied as standard with IP55 protection degree.

Starting from frame size 160 casing, shields, flanges, brake friction surface and the brake protective cover are made of cast iron in order to provide a greater mechanical strength and to be suitable for harsh environment (i.e. marine application). The locking type brake release is realized by means of 1 central screw for sizes 80-112, 2 side screws for sizes 132-315.

MGM BMBM Series

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 0.08kW up to 132kW. BMBM series motors are designed for intermittent duty S3 25%. 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.

What Does the IP Rating Mean?

The IP (Ingress Protection) rating indicates the level of protection provided by the motor enclosure against the ingress of solid objects and water. For example, the BA-BAX series is listed with IP54 protection as standard, with IP55 available on request for specified configurations.

Why is my MGM Motor Brake Not Releasing?

Possible causes include:

Incorrect brake supply voltage.
Faulty rectifier or electrical connection.
A control circuit that is not energising the brake.
Mechanical binding or wear.
Incorrect brake adjustment.

Isolate the equipment and follow the model-specific manual before inspecting electrical or mechanical components.

Can the Brake be Released Manually?

Selected MGM brake motors include a manual brake-release mechanism. Its arrangement varies by series and frame size. Manual release can allow the shaft to move freely, so the driven load must be secured before the mechanism is operated.
