This work deals with the preliminary investigations of a 200-kW induction cage motor with a supply voltage featuring subharmonic injection. The results of the field calculations in the MAXWELL environment are presented for subharmonics of various frequencies. It was found that subharmonics occurring in real power systems can cause overheating and premature failure of this type of machine.
