Abstract

A single phase stepping motor, particularly for clocks, having a disc-like axially magnetized rotor with a number of rotor poles and a stator, which stator is made of at least two stator parts connected with one another via a bridge part carrying the excitation winding. Each stator part on its free end has a smaller number (in comparison to the number of rotor poles) of stator poles, the latter being directed toward the face side of the rotor. In the rest condition of the rotor, a rotor pole with its main part is disposed in the range of a stator pole and with an edge part in the range of the following stator pole.
