Abstract: An electric motor, such as a limited-rotation-angle type, has two or more motor units, including spaced stators enclosing respective rotors on a common shaft. Circumferential, spaced permanent magnets are mounted on the rotors. Stator windings are recessed in slots that are angularly offset with respect to adjacent stator slots. This offset angle between spaced stators is equal to the slot pitch divided by the number of motor units. As a result, the cogging, or super-imposed varying torques of each motor section that occur as the magnets pass a stator slot, are out of phase, and thus substantially cancel out.
