    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.

    Grinding Mill Foundations

    Sep 23, 2014 Most of our work since 2000 has been in developing grinding mill foundations to avoid vibration and unacceptable deflections. On a recent project for a plant in Peru, the client was told by the mill vendor that there was no need to do a systems dynamic analysis on the mill foundations because the mills on that project were gear driven rather than being driven by ring motors gearless drives.
