Advantages of Gearless Motor Drives in Large Ore Grinding

Gearless motors up to 22 MW are in service in many of these ore processing plants. Gearless motor drives are also known as “ring motors" or “wrap around motors." The motor consists of a large number of magnets placed circumferentially on the shell of the grinding mill. This is similar to the rotor of a conventional motor.
