Abstract

See full text

A motor includes a rotor to rotate about a motor axis, and a stator radially outside of the rotor. The rotor includes a shaft extending along the motor axis, and including a collar portion and a screw portion located along an axial direction on an outer circumferential surface thereof, a rotor core surrounding the shaft from radially outside, a rotor magnet fixed to the rotor core, a pair of plate-shaped end plates on both axial sides of the rotor core, and a nut screwed onto the screw portion. The rotor core and the pair of end plates are held between the collar portion and the nut. Each end plate includes a first surface opposite to an axial end surface of the rotor core, and a second surface facing away from the first surface. The first surface includes a slanting surface that slants toward the rotor core and extends radially outward, and is in contact with the axial end surface of the rotor core.
