Abstract
A motor comprises an armature, first and second commutators disposed at either side of the armature, first and second amateur coils wound on the armature through commutator pieces in a double winding back alpha type, and first and second stator coil groups respectively connected through brushes to first and second commutators. A first circuit formed of the first stator coil group, the first commutator, and the first armature coil is connected to a second circuit formed of the second armature coil, the second commutator, and the second stator coil group, in series or in parallel corresponding to a high voltage or a low voltage applied to the motor, thereby the motor shows the same output power without relation to the voltage applied thereto.
