Abstract
A single phase stepping motor, particularly for clocks, with a multi-polar rotor and a multi-part stator, the latter carrying two excitation coils and on its free ends having stator pole teeth which are directed toward the rotor face side as well as a passage opening for the rotor shaft. The stator includes four parts, each of which has the same number of poles with the same distribution, and respectively two are connected with each other on their non-pole ends across one bridge part, the latter carrying one excitation winding. Both of the excitation windings are connected in series.
