Gearless mill drives ABB

The poles of the gearless or synchronous motor (also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive. The fuseless

New gearless conveyor drives . 8th February This reduces the number of main wear parts, so less maintenance is needed, and lengthens the lifespan of the equipment. The expected lifespan for the drive train increases by more than 10 years when compared to traditional geared systems, to a projected in service life of 25 years. Other advantages include a considerable reduction in the drive

Gearless drive system for ThyssenKrupp overland

This gearless drive solution has a number of advantages over the combination of high speed motor and gearbox drives usually used on conveyor systems. The size of the motor is not limited by the size of gearbox available, thus eliminating the necessity to install multi-motor drives. The power required to drive a belt can be provided by just one
