PURPOSE:To reduce the torque loss of a motor due to an eddy current by forming a yoke of a laminate formed by insulating a thin magnetic material between layers to form the laminate wound in a coil shape. CONSTITUTION:A yoke 22 disposed outside of a stator element 20a is formed of a laminate made by winding a thin magnetic material in a coil shape. The yoke 22 is formed in this manner as the laminated to reduce the eddy current generated at the yoke 22 in case of rotating a rotor element 18. Accordingly, the torque loss of a motor due to the eddy current can be reduced to be stably used to a high speed range. |
