Lake Cowal is a gold mine in NSW operated under Evolution Mining. EMF has recently completed cleaning and inspecting the Ball and SAG mill gearless drive motors.

This involves entering the motors through inspection hatches and meticulously brushing and vacuuming the internal windings along with a thorough inspection of the insulation, slip ring and pitch ring. The air gap between the rotor poles, stator and any sensors are checked to ensure the optimal conditions for the drive system.
