TECHNICAL AND COMMERCIAL BENEFITS OF GEARLESS

2021-2-17  Air clutches are used extensively with single and dual pinion low speed drives using synchronous motors. Air clutches are installed between each motor and its associated pinion. The clutch allows the motor to be started uncoupled. With weak power systems, reduced voltage starting of the motors is possible, and on dual pinion drives each motor can be started separately, thereby reducing

2012-2-24  But for synchronous motor drives only dynamic braking can be applied though plugging can be applied theoretically. Regenerative braking cannot be applied to them as they need higher speed than synchronous speed. Dynamic braking is done by disconnecting the motor from supply and connecting it across a three phase resistor.

Advantages of SER drives for SAG mills GoHz

2014-12-19  Advantages of SER drives for SAG mills. For large mills requiring variable speed, the wound rotor motor and SER drive are economical for a total rating of approximately 2MW to 16MW. Above 16MW, the gearless drive (cyclo-converter) is typically used because gearboxes and pinion gears reach their present limit in size.
