Abstract
A synthetic description of the phenomena induced by PWM inverter drive systems are reported and the parameters related to motor reliability are evaluated. The winding quality of brand new motors is addressed, specifically the integrity of the turn or the conductor insulation is checked by applying surge voltage stresses. Finally Partial Discharge (PD) measurements are carried out on an aged 800 kW motor: the outcomes are reported and discussed.
