ABSTRACT:
In a rotary electric machine, coils to be wound around an armature are wound so as to have a good magnetic balance. In a rotary electric machine formed with four poles, ten slots, and twenty commentator segments, a pair of coils that respectively conduct an electric current to the commutator segments adjoining an arbitrary commutator segment at both sides in the circumferential direction are caused to face permanent magnets, that are adjoining poles, to be poles opposite from each other, and one coil is wound in a normal winding state, and the other coil, in a reverse winding state.
