IPC: H02P6/08
Filed: 1986-12-04
Abstract: PURPOSE:To make a brushless synchronous of high performance, by using a half-wave rectification exciting system and a permanent magnet exciting system together. CONSTITUTION:A synchronous motor 1 is connected to a PWM converter 3 which is composed of a rotor having a field winding shorted with a diode in a single phase and with permanent magnets embedded thereto and a balanced multiphase stator winding. A current waveform operation command circuit 2 is synchronized with the rotor position, issuing necessary multiphase current waveform commands. When the multiphase AC current 5 synchronized with the rotor position and modulated by a modulation waveform 4 of bias frequency in amplitude is caused to flow through the stator winding, pulsation magnetomotive force 9 is obtained. Field fluxes 8 becomes nearly constant at any time by means of the diode inserted into the field winding. Torque 11 will be produced by causing the multiphase AC current 7 to flow through the stator winding in which the current component 6 corresponding to torque component is added to the exciting current component 5. By embedding magnets the torque thus produced will increase, so that field weakening can be accomplished.
