    Abstract With the large‐scale development of the ball mill, the direct‐drive gearless ball mill has emerged, eliminating the limitation of the transmission torque of large gear. However, it is difficultto process, transport, install and maintain the gearless ball mill because of its vast volume, and the coils cannot be decoupled freely.
