PURPOSE:To form the motor device for the automobile requiring no brush by controlling the direction of excitation of winding wound no magnetic poles arranged to a stator mounted around a rotor at regular intervals by external signals. CONSTITUTION:The stator core 3 in which the winding 5a-5f is wound on the magnetic poles 4a-4f shaped toward the center is mounted around the rotor 2 on which salient poles 1a-1d are formed at regular intervals. The external signals inputted to a signals input terminal 10 are memorized to a shift register 14. When the memory value of the bits a1-a9 of the shift register 14 satisfies predetermined conditions, the memory value of the bits a4-a8 is memorized to a shift register 17. When the memory value of a bit c1 of the shift register 17 is at a high level, transistors are controlled in the order of 9a 9b 9c. When the memory value of a bit c0 is at a high level, the transistors are controlled in the order of 9a 9c 9b. |
