Induction motors are commonly used in numerous industrial applications. To maintain a reliable operation of the motor, it is important to identify the potential faults that may cause the motor to fail. Bearing failures are one of the main causes of motor breakdown. In some cases, bearings fail due to the electric current passing through them. In this paper, bearing currents in inverter driven five-phase induction motors are studied and a novel solution is proposed. First, theories of shaft… CONTINUE READING
