description A motor includes a stator that includes an annular core back, teeth extending radially outside from the core back and being arranged in a circumferential direction, an insulator covering at least a portion of the teeth, and a coil defined by a conductive wire wound around each of the teeth via the insulator. A radially inside surface of the core back includes core back protrusions extending radially inside and provided with a space therebetween in the circumferential direction. The insulator includes an annular upper lid portion extending radially inside farther than a radially inside surface of the core back at an axially upper side of the core back and a side wall portion extending to an axially lower side from a lower surface of the upper lid portion. At least a portion of the side wall portion is disposed within the space between the adjacent core back protrusions.
