PROBLEM TO BE SOLVED: To achieve torque up efficiently in a reluctance motor. SOLUTION: In the reluctance motor which consists of a stator 2 being equipped with a salient pole 7 with a coil 5 wound and a rotor 3 being equipped with a magnet 11 and having a plurality of salient poles 14 different from the salient pole of the stator 2, the salient pole 14 of the rotor 3 is provided with the first salient pole part 15 for magnet torque generation and the second salient pole part 16 for reluctance torque generation. The first yoke 12, the magnet 11, and the second yoke 13 are attached to the end of a rotor core 9. The first salient pole part 15 abuts on the upper stage 19 of the first yoke 12, and a cavity 22 is made between the second salient pole part 16 and the lower stage part 21 of the first yoke 12. Magnetic circuits for magnet torque and reluctance torque are separated from each other within the rotor 3, so the rotor core 9 becomes hard to be magnetically saturated, and higher torque than that of a usual SR motor can be obtained.
