Abstract:
A motor includes a stator and a rotor. The rotor includes: a plurality of rotor core segments arranged along a circumferential direction of the rotor on the inner side or the outer side of the stator and spaced apart from one another to define a plurality of permanent magnet arrangement slots between the plurality of rotor core segments; a plurality of permanent magnets inserted into the plurality of permanent magnet arrangement slots, respectively; a first frame that couples the plurality of rotor core segments to the plurality of permanent magnets, the first frame being made of a first material; and a second frame that surrounds the plurality of rotor core segments, the plurality of permanent magnets, and the first frame and that couples the plurality of rotor core segments, the plurality of permanent magnets, and the first frame to one another. The second frame is made of a second material different from the first material.
