INNER ROTOR-TYPE MOTOR, BLOWING DEVICE, AND METHOD FOR MANUFACTURING INNER ROTOR-TYPE MOTOR

摘要

This inner rotor-type motor has: a stator (1) having a stator iron core (6) comprising an annular core back section (8) and a plurality of teeth sections (7) that protrude from the core back section (8) to the inner circumferential side, and distributed winding coils that are disposed in respective slots between the plurality of teeth sections (7) and wound around at least two teeth sections (7); and a rotor that is rotatably supported on the inner circumferential side of the stator with a gap between the rotor and the teeth sections (7). The center axis of each of the plurality of teeth sections (7) circumscribes a common circle centered on the center point of the core back section (8), and the circumferential length of the coil is shorter than the circumferential length of each slot when each of the teeth sections (7) is disposed radially.
