Abstract
A motor includes a shaft, a rotor magnet, an armature, an upper bracket, a lower bracket, and a fixing member. An insulator includes magnetic pole tooth insulating portions, each of which covers a separate one of magnetic pole teeth, and a core back insulating portion configured to cover at least portions of upper and lower end surfaces of a core back. A stator core includes a fixing member arranging portion. The core back insulating portion includes a core back insulating projecting portion configured to project in an axial direction away from a surface covering the core back, and including a radially inner surface located radially inward of a radially inner end of the fixing member arranging portion. The core back insulating projecting portion includes a cut portion at a position radially opposed to the fixing member.
