The poles of the gearless or synchronous motor (also called wrap-around motor or ring motor) are directly installed on the pole flange of the mill shell, turning the mill body into the rotor. The stator is then wrapped around the mill. The gearless motor is fed by a cycloconverter which has a rated output frequency of around 5 Hz for the GMD drive.

Increasing availability through advanced Gearless Drive

Gearless Mill Drive (GMD) systems are characterized by having the motor wrapped around the mill like a ring. For this reason, they are often referred to as ring motors. The rotor poles are attached directly to the mill (head) flange, and hence the rotor becomes an integral part of the mill, as shown in figure 4.

Our GMD eliminates all mechanical components of a conventional mill drive system, such as ring-gear, pinion, gearbox, coupling, motor shaft and motor bearings: By mounting the rotor poles directly onto the mill, the mill itself becomes the rotor of the gearless motor.

Literature Review: Gearless Motor Failures A Mill

Sep 10, 2014 The origins of the failure can be traced back to c. 1994 when PT Freeport Indonesia ordered its first gearless drive for their 34 ft SAG mill. The motor had to fit through a tunnel on the road to the site. This necessitated a change in the frame design from that used in older motors to allow clearance in the tunnel [8].
