I was impressed by what I saw on this mill so have one coming for 2022. It is an all new motor for them in that it is an efi but the lower end is the 600 etec and they just redesigned the upper end for fuel injection. 2 strokes always get the bad wrap of people worrying about longevity compared to 4 strokes but once they start letting computors run the motor vs …

The mill gear should be lifted by the pinion causing a downward pressure on the pinion shaft bearing. Mills are made either right or left "hand". There are two methods of identifying the "hand" of the mill. When standing at the feed end of the mill, and facing the mill, if the mill rotates clockwise, it is a right hand mill.

"wrap-around motor" or "ringmotor". The motor rotor is composed of individual poles mounted on the mill flange. The number of poles is based on the required speed of the mill. Thus, the SAG mill motor has 72 poles and the ball mill motors have 56 poles. • Excitation transformer and excitation converter with full wave control.

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.
