Abstract
A stepper motor has electromagnetically driven stator segments facing corresponding rotor segments. In order to reduce vibration of the stator segments, motor body end caps are provided with a stepped annular rim along an inside diameter of a centering sleeve. The stepped rim bears against each axial end of the stator segments, with a radial dimension and an axial dimension bracketing a stator segment end in place.
