ABSTRACT:
A DC motor includes a cylindrical rotor core and a rotor coil wound around the rotor core. The rotor core has shallower slots and deeper slots, circumferentially and alternately disposed in the peripheral surface thereof at angular intervals about the center axis thereof. Each shallower slot includes inner and outer radially aligned sections, while each deeper slot includes inner and outer radially spaced sections and a neck section interposed between the corresponding inner and outer sections. The rotor coil includes U-shaped formed wires, each including inner and outer leg portions and an intermediate portion which interconnects the inner and outer leg portions. The angle between the inner leg portion and the intermediate portion is larger than 90.degree.. Each of the formed wires has its inner leg portion inserted in the inner section of a shallower or deeper slot and has its outer leg portion inserted in the outer section of the Nth slot as counted in a circumferential direction from the slot in which the corresponding inner leg portion is inserted, so that its intermediate portion projects from and is inclined to the rear end face of the rotor core. N is a natural number greater than two. The intermediate portions of the formed wires occupy a donut-shaped volume on the rear end face of the rotor core.
