Abstract: A D.C. motor includes a rotor and a stator with chordally oriented electromagnetic units, with windings pulse energized to establish a rotary force on the rotor as a result of the non-radial orientation of the driving forces. Each electromagnetic unit including a pole is extended along a substantially chordal line of the motor. All rotor poles are connected to a shaft by a radial crank arm and may be integrally or separately formed. A sensor detects pole alignment to then pulse the windings, and generate opposing magnetic forces to rotate the rotor. The winding establish opposite polarity at the adjacent pole ends of aligned poles to drive the rotor. A D.C. motor connected to the rotor, or special internal poles may be provided to align the poles for starting the motor. A plurality of the motors mounted to a common shaft with the electromagnetic units in the adjacent motors offset from each other and sequentially pulsed to establish continuous rotation.
