Abstract
A motor (100) includes an annular stator (10) and a rotor (20) disposed on an inner circumferential side or outer circumferential side of the stator (10). The stator (10) includes an annular stator core (11) and multi-phase coils (12) attached to the stator core (11). The multi-phase coils (12) each include a plurality of coil portions (1U, 2U, 1V, 2V, 1W, and 2W). The motor (100) further includes a switching unit (30) that switches connection states of the plurality of coil portions (1U, 2U, 1V, 2V, 1W, and 2W) of the coils (12). The switching unit (30) is disposed on the inner circumferential side or outer circumferential side of the stator (10) and the rotor (20).
