り永久磁石側に突出していることを特徴とする電動機。A stator comprising a disc-shaped excitation coil, a magnetic pole tooth plate made of a disc-shaped soft magnetic material formed on a side surface of the excitation coil, and a yoke that guides magnetic flux induced by the excitation coil to the magnetic pole tooth plate, and the magnetic pole. A disk-shaped permanent magnet facing the tooth plate, with N and S poles.
It consists of a rotor with permanent magnets magnetized alternately at equal angles in the circumferential direction. Extending magnetic pole teeth are formed alternately and at an angle equal to the angle of each magnetic domain of the permanent magnet, and each of these two types of magnetic pole teeth has a central flat part facing the permanent magnet on the inside, and an outer peripheral edge on the inside. An electric motor characterized by protruding closer to the permanent magnet side.
