ABSTRACT:
A direct current motor comprising a field magnet with 2np magnetic poles, magnetized to N and S poles with equal angular intervals, where n is an integer of 1 or more and p is an integer of 2 or more; a magnetic member for closing the magnetic circuit of the magnetic circuit of the magnetic poles of the field magnet; n(py.+-.1) armature coils disposed in such a manner that the angular intervals of the electrically conductive portions of the armature coils, contributing to the generation of torque in the armature coils, are substantially equal to the magnetic pole width of the field magnet, where y is an integer of 3 or more; a wave-winding-type armature on which the armature coils are disposed, overlapping on each other, with an equal pitch, the wave-winding-type armature being directed towards the field magnet within the magnetic circuit; electric power supply control device for commutating the commutator current np(py.+-.1) times or 2np(py.+-.1) times per one rotation of the armature coils; and a rotating shaft for rotatably supporting the wave-winding-type armature or the field magnet, the rotating shaft being rotatably supported by bearings mounted on an outer casing of the motor.
