Claim:
1. A motor comprising: a two-layer rotor including an A-phase rotor and a B-phase rotor that are stacked together, wherein the A-phase rotor includes two A-phase rotor core bases and a field magnet arranged between the A-phase rotor core bases, and each of the A-phase rotor core bases includes claw poles arranged at equal intervals in a circumferential direction, and the B-phase rotor includes two B-phase rotor core bases and a field magnet arranged between the B-phase rotor core bases, and each of the B-phase rotor core bases includes claw poles arranged at equal intervals in a circumferential direction; and a two-layer stator including an A-phase stator and a B-phase stator that are stacked together, wherein the A-phase stator includes two A-phase stator core bases and an A-phase winding arranged between the A-phase stator core bases, and each of the A-phase stator core bases includes claw poles arranged at equal intervals in a circumferential direction, and the B-phase stator includes two B-phase stator core bases and a B-phase winding arranged between the B-phase stator core bases, and each of the B-phase stator core bases includes claw poles arranged at equal intervals in a circumferential direction; wherein θ1+|θ2|=90° is satisfied, where θ1 represents, in electric angle, an angle of the B-phase stator relative to the A-phase stator in a clockwise circumferential direction, and θ2 represents, in electric angle, an angle of the B-phase rotor relative to the A-phase rotor in a counterclockwise circumferential direction.
