Abstract

PURPOSE:To obtain for an output voltage of a synchronous motor a voltage waveform with identical frequency and phase with a caused voltage of an power source circuit, by connecting a synchronous motor and a coupler of the synchronous motor in parallel with a power source circuit of a motor without commutator. CONSTITUTION:In a beta control system which controls a load current conversion timing, a synchronous motor 11 is connected in parallel with a motor without commutator THM with an intervention of a transformer 12, and because the number of pole are identical it revolves with a same number of revolution as the motor THM. Therefore a waveform of a generated AC voltage of a synchronous motor 13 connected with the synchronous motor 11 with identical number of pole and phase becomes a rippleless since waveform with identical frequency and phase with the caused voltage of the motor THM. The voltage of this generated output is compared with a set value by a comparator 14, converted into a position signal with a phase angle and fed to a cyclo-convertor 10 through a beta logical circuit and a alphabeta composite logical circuit, and this is to be controlled.
