The motor includes a fixed field magnet having 2mn poles (m being a positive integer of 1 or more, n being a positive integer of 2 or more) which are magnetized alternately to N and S polarities in equal angular spaces, a magnetic material member for closing the magnetic path of the field magnet, a rotating shaft supported by bearings provided in the housing of motor, and an armature which is secured to the shaft for rotation in the magnetic path and facing the field magnet poles. A first series of m(2n+1) armature windings are mounted on the armature and are juxtaposed with respect to each other at equal pitches, the angular spacing between the conductor portions, which contribute to generate torque, of the armature winding being equal to the angular width of the field magnet pole. A second series of m(2n+1) armature windings are also mounted on the armature and are juxtaposed with respect to each other at equal pitches, the angular spacing between the conductor portions, which contribute to generate torque, of the armature winding of the second series also being equal to the angular width of the field magnet pole. The first series of the m(2n+1) armature windings and the second series of the m(2n+1) armature windings are superposed on each other and are disposed, with respect to each other, out of phase by 1/(2n-1) of the angular width of the field magnet pole.
