Monorail Geared Motor Drives - BM Series

The BM geared motor for more efficient electric overhead conveyors. 
The BM09 for low load applications fulfills the requirements of directive C1 of VDE 3643.

Features and benefits

Bauer geared motors have been used in material handling for more than 20 years to drive monorailoverhead conveyors.

The ideal solution for floor conveyors

The clutch lever is always on the "L" side of the gear motor, the side opposite the motor. This enables the gear motor to be designed with an output shaft on both sides, which also allows it to be used as a drive for floor conveyors. 

Reliable operation even in hostile environments

The drives are supplied with IP65 degree of protection as standard. This is a great advantage for operation in dusty environments. 

Low-noise operation 

The noise emission from two-ratio gear motors is lower than three-ratio motors with the same ratios. The first gear wheel, which is primarily responsible for noise, has a smaller diameter than three-ratio models.

Low operating costs 

Gear motor size BM09 in the load range to approx. 2000 kg has worm gears for the first ratio and spur wheels for the second ratio. The specially developed worm gears with very low ratios provide very high efficiency, similar to that of bevel gear drives. 

Fast maintenance of the attached brake 

The gear motors are fitted with a brake for braking and positioning the electric overhead conveyor. Motors from size 80 (0.37kW) are supplied with an attached brake. The brake is mounted externally on the cast ventilation hood and keeps service times as low as possible.


Product range
Power rating up to 0,55 kW.
