Beat the grind

Brett Masters, Invertek’s Sales Partner in Brisbane, Australia, said: “After installing the Optidrive E3, the machine was transformed in terms of stability while torque performance could be raised from 50Hz to 60Hz without causing any issues.

“Both the motor and Optidrive E3 were tested extensively under hours of continuous, very demanding loading. Despite this onerous testing regime, motor and load temperatures were kept low and there were no problems with tripping.

“Even when there was poor power available, the grinding machine remained acceptably powerful and could carry out its function without any problems,” he added.
