PROBLEM TO BE SOLVED: To obtain higher rotating torque by realizing higher magnetization with hybrid variable reluctance formed by combining a permanent magnet to a rotor. SOLUTION: The DC motor 11 is provided with permanent magnets 19a, 19b for stator provided opposed with each other. Teeth 22a are formed to a core 22 of an armature 20, and teeth bars 22b are also formed to the end part thereof. A permanent magnet 24 for rotor in which the magnetic pole changes is provided in the circumferential direction to couple the end portions of the adjacent teeth bars 22b, and the same magnetic pole is provided opposed with each other in the adjacent permanent magnets 24 for rotor. A coil 23 is formed by centralized winding in the right direction to each tooth 22a. When a current is fed to the coil 23, the end portions of the predetermined tooth 22a and the tooth 22a located in the opposite side to the predetermined tooth 22a about the rotating shaft 18 are magnetized in different magnetic poles. Winding end of coil 23 is connected to each commutator piece. The brush is connected to move toward each commutator piece with rotation of the armature 20.
