Roller Conveyor Motors

Powerful Drive, Extra Rugged

Working roller conveyors in reversing roller mills are almost exclusively equipped with directly driven rollers today. The requirements placed upon the drive’s mechanical design are extremely high. To meet them, we developed our three-phase roller conveyor motors for inverter operation. They are designed as totally enclosed three-phase asynchronous motors.

Roller Conveyor Motors – a Brief Summary of Their Strengths

Increased efficiency
The torsion-resistant housing made of spheroidal iron is particularly rugged against mechanical loads. In addition, the ring rib housing prevents the accumulation of scale dust.

More power

Torque reserves allow for high, up to 4-fold impulse torques. Inverter-proof up to a mains voltage of 460 V, optionally available with special insulation up to 690 V.

More flexibility

Optimum utilization with inverter infeed through winding adjustment to the respective voltage/ frequency. Optionally with installed rugged rotary pulse encoder.

Roller Conveyor Motors – Typical Uses

The rugged, non-ventilated roller conveyor motors are particularly suitable for harsh operation in roller mills under adverse application conditions, in working and transport roller tables, with high ambient temperatures, high humidity and occurring scale dust.
