Abstract
A direct current motor is provided with a field magnet having l(2m+2n) alternating N and S poles (l and m being positive integers of one or more and n being a positive integer of two or more) that are magnetized within segments of equiangular width about the field magnet, a magnetic-material member for closing the magnetic path of the field magnet, and an armature having 2ln armature windings distributed thereon 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 a field magnet pole.
