Abstract
A three-phase induction motor that is rotationally driven in response to supply of AC power from an inverter including a switching element formed by using a wide bandgap semiconductor includes: a stator including a stator slot having an open slot structure for inserting a former-wound coil; and a rotor including a rotor slot into which a secondary conductor is inserted, the rotor being disposed inside the stator via a gap. Assuming that the number of rotor slots is N, the number of stator slots is N, and the number of poles is N, N, N, and Nare set such that the relationship of N≤N−N−6 is satisfied.
