Title:
SYNCHRONOUS MOTOR
Document Type and Number:
Japanese Patent JPS59178949
Kind Code:
A
Abstract:
PURPOSE:To reduce the irregular rotation by disposing one polarity field pole at an equal pitch, and disposing the other polarity field pole at different pitch from the adjacent two one polarity field poles. CONSTITUTION:A stator 11 has slots 12 and slot teeth 13. A rotor 31 has a permanent magnet 32 and field poles 33. The circular center 36 of the N-polarity field pole exists on a lnear line crossing perpendicularly the center of the rotor 31. On the other hand, the circular center 36 of the S-polarity field pole is displaced by deviations L1, L2, L3, L4 from the certain point disposed at an equal pitch from the N-polarity field pole. This is performed by altering the shape of the S-polarity field pole.
