The GMD is also known as "wrap-around motor" or "ringmotor". Almost 25 years later, the first GMD with 12.0 MW power and 13.0 rpm was installed in the minerals industry. Since then, ... transmission of the torque between the motor and the mill is done through the magnetic field in the air gap between the motor stator and the motor rotor ...
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.
