Abstract:
A motor is disclosed, the motor including a stator core formed with a cylindrical space at an inner surface and formed at an inner circumferential surface with a plurality of teeth protruding toward a center, a cylindrical rotor rotatably mounted at the space and formed with a plurality of pockets for inserting a permanent magnet, a rotation shaft coupled to the center of the rotor and receiving a rotation force generated by interaction between the stator core and the rotor, a nut member connecting the rotor to the rotation shaft by press-fitting the rotor at a periphery to an axial direction of the rotation shaft and press-fitting the rotation shaft at an inner circumferential surface to the axial direction of the rotation shaft, and a key unit inhibiting a slip between the rotor and the nut member.
