A single phase stepping motor, particularly for clocks, with a disc-like, axially magnetized rotor with a number of poles and a stator, the latter being made of two stator parts connected with one another via a bridge part, the latter carrying the excitation winding, of which each stator part on its free end passes into a smaller number (in comparison to half of the rotor pole number) of main poles, the main poles being directed towards the face side of the rotor, at least a part of the main poles being provided with auxiliary poles. Both stator parts lie in a first plane at least in the region of the stator poles, and the rotor is arranged in a second plane parallel thereto. A return disc is disposed on a face side of the rotor, which faces away from the stator poles.
