text: To this end, according to the present invention, there is provided a commutator motor comprising: a yoke; a magnetic field portion secured to the inner wall of the yoke; a shaft disposed within the yoke so as to be able to rotate freely; an armature secured to the shaft having windings constructed by winding wire by a lap-winding method into slots formed on the outer circumferential surface of a core so as to extend longitudinally; a commutator secured to the shaft including a hollow cylindrical insulating resin portion and a plurality of segments held on an outer circumferential portion of the insulating resin portion with spaces between adjacent segments being held by the insulating resin portion; a plurality of brushes contacting the surface of the commutator; and a equalizing member electrically connecting segments which are to have the same electric potential.
text: In a commutator motor of the above construction, segments 16 which are to have the same electric potential are electrically connected using the terminals 24 which are equalizing members, not only preventing circulating currents from flowing through the circuits into the brushes due to differences in induced voltage arising in each of the circuits of the windings 21 between the brushes, but also preventing imbalances in electromagnetic attraction from arising due to differences in the numbers of coils in each of the circuits.
