A motor is provided having a consequent-pole type rotor that has soft magnetic material poles and magnetic poles positioned around the rotor in an alternating manner. A convex surface on each of the poles is formed as a surface in which a midpoint of the convex surface has a radial distance from the rotation axis that is greater than a radial distance of the circumferential edges of the convex surface from the rotation axis. A radial width of a first magnetism transfer part of a cylindrical yoke and a radial width of a second magnetism transfer part of the magnetic pole fulfill a relationship such that an appropriate balance of the magnetic resistance between the first magnetism transfer part and the second magnetism transfer part is achieved. As a result, cogging torque is reduced without reducing output torque.
