Design and dynamic behavior of large Ring Motors for ...

2021-8-22 · Ring Motor drive a grinding mill without contact between rotating and fixed parts. This concept avoids girth gear and pinions, which are used for conventional mill drives. The stator of the Ring Motor is wrapped around the mill as a ring. Due to the large size, the stator is fabricated and transported in segments. At site, the stator segments are mounted together around the mill. Vertical anchor bolts fix the stator to two sole plates in the foundation. The rotor of this synchronous motor consists of poles installed at a flange of the grinding mill.
