摘要

The rotor (3) has an iron core (31), an iron core (32), and an iron core (33). The iron core (31) has a slit (34). The iron core (32) has a slit (34), an inner core portion (32a), and an outer core portion (32b) separated from the inner core portion (32a). The iron core (33) has a slit (34), an inner core portion (33a), and an outer core portion (33b) separated from the inner core portion (33a). The iron core (31), the iron core (32), and the iron core (33) are laminated in the axial direction, and at least one of the inner core portion (32a) and the outer core portion (32b) is a permanent magnet (36) in the circumferential direction. ) Facing the protrusion (32c).
