An electric motor produces an increased output torque for a given amount of input electrical current by using two magnetic field parts adjacent a winding part. Preferably, the winding part is disposed between the field parts. In a first embodiment, the two field parts are radially spaced from one another with the winding part therebetween. One field part is mounted on a hollow post through which an output shaft extends and on which a bearing is mounted for rotatably supporting thereon the winding part. In a second embodiment, the field parts are axially spaced from one another with the winding part therebetween. Axially spaced mounting wheels are connected to the output shaft for supporting therebetween a plurality of windings. The third embodiment includes a plurality of output shafts and a rotor suspended by interaction between pinions on the shafts and rotor gears.
