PURPOSE:To provide small size and high performance and to reduce the causes of generating heat in a 4-phase exciting DC motor-driven rotary electric machine by separating an induced counter electromotive force, induced power from a power source current, and recovering it by a double voltage to a battery power source. CONSTITUTION:A 4-phase exciting DC motor-driven rotary electric machine is composed of a stationary field pole 1, a field pole-exciting coil 4, phase terminals 5, an exciting magnetized pole 6, a rotor spindle 9, etc. Further, rotor pole widths are formed equally, and N-, S-poles are so combined as to be alternately engaged with each other, power induced by a 4-phase exciting rotary controlling method from the stationary field pole continued to the N-, S-poles is separated from a power current by bridged rectifiers to be doubled, and returned to a battery power source. A rotary exciting current from 1 phase over to 4 phases flow to the pole 1 to rotate at from low to high speeds, and the speed is controlled by an accelerator pressing command signal. Further, all exciting currents are stopped by an accelerator press release signal, all the pole coils are switched to generating function to obtain generated power, and recovered currents are supplied to a power source. |
