Abstract
A motor includes a stator having a cylindrical shape and a rotor having a cylindrical shape provided in the stator and is rotatable about a central axis of the stator and is used to drive a driving wheel of a vehicle by rotation of the rotor. The rotor has a cage and a plurality of permanent magnets provided on an inner side of the cage and disposed side by side in a circumferential direction. The cage includes a plurality of first secondary conductors extend in a radial direction. The plurality of first secondary conductors are configured such that the permanent magnet is interposed between inner parts of first secondary conductors on opposite sides in the circumferential direction.

A motor comprising:
- a stator having a cylindrical shape;
- a rotor having a cylindrical shape provided in the stator and is rotatable about a central axis of the stator, a driving wheel of a vehicle being driven by rotation of the rotor, wherein
- the rotor has a cage and a plurality of permanent magnets disposed side by side in a circumferential direction on an inner side of the cage,
- the cage includes a plurality of secondary conductors that extend in a radial direction, and
- the plurality of secondary conductors are interposed between inner parts of secondary conductors on opposite sides in the circumferential direction to form a magnetic barrier between adjacent permanent magnets.
