9 out of 10 motors on drives have high shaft voltages that reduce electric motor life.
3 out of 10 motors are failing directly due to these shaft voltages in S.A .
Yes, a 5 year research project shows this startling result, and is therefore no surprise why most overseas companies and motor manufacturers are installing earth rings as Standard on their electric motors. Increase Motor Life and a 33% reduction in breakdowns is a large saving in any budget.
No insulated bearings required for low voltage motors thereby also saving servicing costs, as well as no waiting for availability of insulated bearings or housings, and above all use it for the “LIFETIME of the motor”
