Abstract
A stepper motor having a stator and a rotor, the rotor having a shaft formed with an axial bore. A pair of bearings carried by the stator rotatably support the shaft. A stud is fixed within the bore and has an enlarged head extending radially beyond the external contour of the shaft into axial alignment with at least part of one of the bearings. Engagement between the stud head and the bearing limits axial movement of the rotor with respect to the bearing.
