Influence of inverter harmonics on continuous performance of a permanent magnet drive

Abstract:
Modern electric motors are often controlled by inverter topologies. Challenging package and weight requirements in all industrial sectors lead to a high power density of the electric drive system in all components. Therefore, dependencies between the different components can create parasitic effects, which were neglected in the past. One of these effects is the influence of the inverter harmonics on the performance of an electric motor. This paper deals with a study of the losses and continuous performance of a high power density permanent magnet motor fed by a two-level voltage source inverter.
