A motor includes a rotor and a stator. The rotor includes a plurality of magnets, which function as first magnetic poles, and salient poles, which function as second magnetic poles. A ratio X1:X2 of a quantity X1 of magnetic pole portions of the rotor, which is the sum of the quantity of the magnets and the quantity of the salient poles, and the quantity X2 of slots is 2n:3n (n being a natural number). The sum of a magnetic pole occupying angleθ1 of the magnet and a magnetic pole occupying angleθ2 of the salient pole is 360°. The magnetic pole occupying angleθ1 is set in a range of 180°<θ1≰230°.
