ABSTRACT:
A small sized electric motor of a sectionally non-circular housing has a pair of magnets oppositely positioned therein in the lengthwise direction thereof and a rotor positioned between the magnets. A pair of fulcrums oppositely located on the housing in the length-wise direction thereof diametrically across the rotor, and a pair of elongated brushes, each has one end part secured to each of the fulcrums and the other end part elastically pressed against the commutator of the rotor at a point thereof to determine the electric displacement point with the angle 120.degree. displaced with respect to the magnetic line of force caused by the magnets. A winding is wound around the core structure of the rotor and has the initial ends and the wound ends each connected to a predetermined number of connector terminals of the commutator with the angle 120.degree. displaced with respect to the commutator.
