Abstract
A direct current motor is provided with a field magnet having 4 mn alternating N and S poles (m being a positive integer of one or more and n being a positive integer of two or more) that are magnetized within segments of equi-angular width about the field magnet, a magnetic-material member for closing the magnetic path of the field magnet, and a rotatably mounted armature having m(2n+1) armature windings equally distributed thereabout in a non-superposed manner with respect to each other and in a face-to-face relationship with respect to the field magnet poles, each winding having an angular spacing between those conductor portions thereof that contribute to the generation of the torque that is equal to the angular width of the field magnet poles.
