Abstract
PURPOSE:To reduce a loss of the eddy current flowing inside a yoke of stationary element at the time of high speed rotation by forming the yoke if stationary element from a plurality of a concentric circle magnetic material rings centering on a rotary axis of a rotor. CONSTITUTION:A plate-like magnet 14 is used as a rotor 10 by multipolar magnetization of a parallel direction with a rotary axis 12 to a magnetizing direction, and an armature coil 24 and a yoke of stationary element 40 to be a magnetic path of a rotor flux are provided to the side of the stator. The yoke of stationary element 40 is composed from the plural number of a concentric circle magnetic material rings 40a-40c centered the rotary axis 12 of the rotor 10. The eddy current produced by the rotation of the rotor 10 is dividedly applied to each of magnetic material rings 40a-40c.
