ABSTRACT OF THE INVENTION One Lobed Motor A digital stepping motor having n rigid tubular rotor arranged within a stator, in a housing, the stator having an arrangement of spline teeth adjacent one end thereof on a portion of the housing. The rotor has an array of spline teeth disposed at one end thereof, and a deflectable dia- phragm at the other end thereof. The deflectable diaphragm is fixedly attached to an output shaft. The tubular rotor has an axis of rotation which is slightly skewed with respect to the axis of rotation of the output shaft during energization of the motor when the rotor is attracted to the stator. The stator comprises a plurality of equi-angularly spaced coils, the sequential energization of which causes sequential circumferential engagement of corresponding external and internal spline teeth between the rotor and the spline teeth on the end cap, creating an orbiting motion within the rotor, and a subsequent rotation of the output shaft.
