An electric motor, comprising: an armature having a plurality of spaced apart posts defining a plurality of spaced apart winding slots; a commutator having a plurality of commutator bars (12 1-18), a stator disposed coaxially with the armature, the stator having a plurality of spaced apart field coils; the armature including: a first coil (25 1) having a first plurality of winding turns wound only in a first pair of spaced apart ones of the winding slots and; a second coil (25 2) having a first and second subcoil portions (2A, 2B) serially coupled together, the first subcoil portion having a plurality of winding turns wound in the first pair of spaced apart winding slots, and the second subcoil portion having a plurality of winding turns wound in a second pair of spaced apart winding slots that are circumferentially offset from the first pair of spaced apart winding slots, wherein the first coil and the first subcoil portion of the second coil (25 2) are wound with different number of winding turns so that a resultant magnetic axis of the first coil (25 1) lies at a predetermined angular position relative to a first pair of commutator bars to which the first coil (25 1) is secured; a third coil (25 3) having a first and second subcoil portions (3A, 3B) serially coupled together, the first subcoil portion having a plurality of winding turns wound in the second pair of spaced apart winding slots, and the second subcoil portion having a plurality of winding turns wound in a third pair of spaced apart winding slots that are circumferentially offset from the second pair of spaced apart winding slots, wherein the second subcoil portion of the second coil (25 2) and the first subcoil portion of the third coil (25 3) are wound with the same number of winding turns so that a resultant magnetic axis of the second coil (25 2) lies at a predetermined angular position relative to a second pair of commutator bars to which the second coil (25 2) is secured; wherein the armature further includes a fourth coil (25 4) having a plurality of winding turns wound only in the third pair of spaced apart winding slots, wherein the second subcoil portion of the third coil (25 3) and the fourth coil (25 4) are wound with different number of winding turns so that a resultant magnetic axis of the third coil (25 3) lies at a predetermined angular position relative to a third pair of commutator bars to which the third coil is secured; characterized in that the number of commutator bars is an integer greater than the number of winding slots but less than twice the number of winding slots. an armature having a plurality of spaced apart posts defining a plurality of spaced apart winding slots;
