ABSTRACT:
This invention relates to an improvement in a stepping motor, comprising a stator housing with electromagnets being annularly positioned therein, a flexible membrane rotatably mounted over said electromagnets on a bearing block shaft, said shaft being axially positioned within the stator housing, said membrane being a magnetically-conducting annular disc, adapted to act as a rotor, the improvement comprising race means whereby the membrane is prestressed on the side facing away from the electromagnets by pressing and its conically deformed by an amount coordinated to the step size and holding moment of the stepping motor, and including contact surface means corresponding with the race means on the one hand, and with the stator housing on the other hand, said surface means being equivalent at the upper side and the underside of the membrane.
