Abstract

PURPOSE: To reduce battery capacity by controlling the energy of permanent magnet by the switching of magnetic circuit and by utilizing the energy of rotor driving by constituting the driving device with rotor, stator, permanent magnet, and magnetic resistance switching element.
CONSTITUTION: When the rotor 6 is at rest, no input voltage is applied to the magnetic switching elements 4a to 4d consisting of magnets wound with coil and loop form of magnetic fluxes 9a, 9c, 8a, and 8b generate in the permanent magnet 7 and the rotor 6. And, when the rotor is drived, current flows in the coils 4a and 4d and thereby magnetic fluxes generate in the states 10a and 10b, the stator 5 is magnetized to the polarity, as shown in Fig., and the rotor 6 is turned through 180° by a repulsion between the rotor 6 and the N-pole. Then, by the one second later driving of the rotor 6, the magnetic switching elements 4c and 4b are saturated with magnetism, the N and S poles of the stator 2 generate on the opposite side, and the rotor 6 is drived. Thus, the magnetic energy of the permanent magnet 7 can be utilized as energy for rotor driving by being controlled by the switching of magnetic circuit.
