Abstract:
According to one embodiment, an induction motor includes a stator and a rotor. The stator has a stator coil disposed at a stator core having a plurality of stator slots. The rotor has a rotor core rotatably provided with respect to the stator. The rotor core includes a plurality of rotor teeth and a rotor slot formed between the plurality of rotor teeth and having a rotor conductor disposed therein. The rotor teeth include a teeth main body and a flange. The teeth main body extends in a radial direction of the rotor core. The flange extends in a rotating direction of the rotor core from a distal end of the teeth main body. Then, a recessed surface is formed on at least part of an outer circumferential surface of a radial outer side in the flange.
