PURPOSE:To make phase switching of each current smooth, by distributing torque command signals at the output ratio of a plurality of the rotary position signals of a permanent magnet rotor, amplifying the signals, and conducting stator windings. CONSTITUTION:A rotary-position-signal operating circuit 9 outputs multiphases of the rotary position signals of a permanent magnet rotor 1. Said rotary position signal is inputted in a distributing circuit 22. In the distributing circuit 22, the torque command signals of a motor are distributed at the output ratio of the rotary-position-signal operating circuit 9. A stator-winding driving circuit 6 sequentially supplies the currents in accordance with the outputs of the distributing circuit 22 to a plurality of stator windings 2a-2c. |
