Abstract
A motor includes a two-layer rotor and a two-layer stator. The two layer rotor includes an A-phase rotor and a B-phase rotor that are stacked together. When 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, θ1+|θ2|=90° is satisfied.
