Abstract:
A rotary electric machine includes: a stator including a stator core and a stator coil wound around the stator core; and an annular outer rotor including an outer core disposed around an outer periphery of the stator and a plurality of outer magnets arranged at intervals in a circumferential direction, in which the stator core has an annular yoke and a plurality of outer teeth protruding radially outward from an outer periphery of the yoke, the outer magnets are magnetized in the circumferential direction such that magnetization directions of the outer magnets adjacent to each other in the circumferential direction are opposite to each other in the circumferential direction, and a circumferential distance of a gap between the outer magnets adjacent to each other is 1.5 times or more a disposition pitch in the circumferential direction of the outer teeth.
