Abstract

Current and voltage harmonics lead to iron losses in motors. As the iron losses have the largest portion of total losses in many motors, harmonic analysis of motors is of paramount importance. In this study, we compared the new designed permanent magnet assisted synchronous reluctance motor (PMSynRM) and synchronous reluctance motor (SynRM) with an industrial induction motor (IM) in terms of harmonic currents and harmonic voltages. To investigate the performance of the motors in terms of harmonic distortion, an industrial frequency converter based on direct torque control (DTC) strategy is adopted. The study shows the high harmonic injection of frequency converter to the system.
