Abstract

A motor includes a stator and a rotor rotatably coupled to a rotation shaft. The rotor includes: 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 permanent magnet arrangement slots between the rotor core segments; permanent magnets inserted into the permanent magnet arrangement slots, respectively; and a rotor frame including rotor frame pins that fix each of the permanent magnets between the rotor core segments. Each of the rotor core segments defines a rotor core hole that extends parallel to an axial direction of the rotation shaft. The rotor frame comprises: a base formed to surround the plurality of rotor core segments and the plurality of permanent magnets in a direction parallel to an axial direction of the rotation shaft; and a plurality of permanent magnet fixing jig holes formed only at an inner end between the inner and outer ends of the base to expose the plurality of permanent magnets.
