PROBLEM TO BE SOLVED: To solve a problem that a fuel battery is weak in overvoltage, therefore an inverter and the like of a car may get out of order when high-speed driving causing a large load of a back electromotive force to the fuel battery and also bringing a very dangerous situation, meantime, if a motor with a small induction force is used, it ends up with a small output and low efficiency. SOLUTION: A motor comprises two first rotating units 2 respectively mounting a permanent magnet 1, and a second rotating unit 3 carrying a magnetic saliency inserted between the two, and uses a rotor 5 connected to the direction of a rotating shaft 4. The number of permanent magnets can be reduced employing a reluctance motor to a part of the rotor 5 as well as the occurrence of an induction force can be suppressed. Furthermore, the salient ratio is raised by magnetically saturating the second rotating unit 3 effectively making use of flux diffraction 18 that is formed by mounting the first rotating units 2 at both sides of the second rotating unit 3. A reluctance torque occurring at the second rotating unit 3 is enlarged so that the whole torque is entirely enlarged, and then a high-output motor can be obtained. |
