Provided is a magnetic wave gear device (1A) in which: a low-speed rotor (10) is disposed between a stator (30) and a high-speed rotor (20) and has first magnetic bodies (11) and first permanent magnets (12), magnetic poles of which face the same direction, alternately in a circumferential direction; the high-speed rotor has second magnetic bodies (21) and second permanent magnets (22), magnetic poles of which face the same direction as the first permanent magnets, alternately in the circumferential direction; the stator has third magnetic bodies (31) provided with slots (34) in which coils (33) can be wound, and third permanent magnets (32), magnetic poles of which face the same direction as the first permanent magnets, alternately in the circumferential direction; and a relationship of Ns=Nl±Nh is satisfied when Nl is the number of magnetic poles of the low-speed rotor, Nh is the number of pole pairs of the high-speed rotor, and Ns is the number of slots of the stator. |
