PURPOSE:To enhance the efficiency and the output torque with a simple configuration by controlling to flow currents to exciting coils by the output of a position detector secured to a body separated at the prescribed angle of an electric angle from each other. CONSTITUTION:A rotational shaft 1 is rotatably supported to a body, punched in the shape having salient poles 2a-2l, and laminated to form a rotor 2, and the center of the rotor 2 is secured to the shaft 1. A stator 25 having poles 25a-25h is formed by laminating silicon steel plates, and exciting coils 26a, 26b, 26c, 26d are mounted at poles 25b, 25d, 25f, 25h, respectively. Coils 11 to become position detectors are secured to the body separated at the prescribed angle of electric angle, and the coils 26a-26d are controlled to be energized by the output of the coil 11. |
