PURPOSE:To transmit a rotary torque to the desired member in limited shape and size by providing a toothform on the outer periphery of a rotor yoke and forming the desired member capable of engaging with the yoke. CONSTITUTION:A magnetic circuit is formed of a rotor yoke 6, a magnet 4 and a stator yoke 8. The pole position of a magnet 4 is detected by a Hall element 14, the obtained signal is supplied to a controller, a current to a coil 9 provided on the yoke 8 is controlled to generate a rotary force. A tooth form 17 is formed on the outer periphery of the yoke 6, and the yoke 6 is formed in a gear. A transmission element 16 of a front loading mechanism side is engaged, for example, with the toothform 17. Accordingly, the rotary torque of the rotor is transmitted through the element 16 to the mechanism. |
