PURPOSE:To obtain a permanent magnet rotary machine, by blocking magnetism having opposite polarity from that of a magnetizing pole through repelling magnetism of an intermediate counter-field magnet. CONSTITUTION:A counter-field permanent magnet 56 is mounted between a rotor magnetizing pole 35 and S, N poles 36, 37 of a rotor magnetic disc. The permanent magnet 56 functions as a repelling field for blocking magnetism. The rotor magnetizing pole 35 constitutes a rotary field pattern magnetizing pole through the magnetism of a rotor permanent magnet 40. Magnetism receiving/feeding position varies as the rotor rotates and the magnetizing pole is converted into a magnetic polarity corresponding to rotary pattern so as to constitute a rotary field having rotary field phase. S and N polarity supply poles 29, 30 are interlocked to slide each other so as to enable field control of forward rotation, reverse rotation and stopping position thus providing respective field rotary operation. |
