Abstract: PROBLEM TO BE SOLVED: To provide a motor 1 which can increase the ratio of magnet torque in an outer side magnetic circuit and which can improve output torque by having a composition in which reluctance torque in an inner side magnetic circuit can be fully exhibited.SOLUTION: In a magnetic circuit of a rotor 6, relation between a rotor outer side salient pole width P6 and a rotor outer side magnet width P13 is within the range of 3.5 0.5. Thereby, the relation among the rotor outer side magnet width P13, the rotor outer side salient pole width P6, and the rotor inner side salient pole width P7 can be set properly. Since the ratio of magnet torque in the outer side magnetic circuit can be improved and magnetic saturation in a rotor yoke section can be suppressed, therefore, reluctance torque can be fully exhibited even in an inner side magnetic circuit.
