Abstract

A single phase stepping motor, particularly for clocks, with a rotor having several pole teeth 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 has an equal or smaller number (in comparison to the rotor pole number) of stator pole teeth as well as a passage opening for the rotor shaft, the stator pole teeth being directed towards the face sides of the rotor. Each rotor pole tooth comprises a main pole and an auxiliary pole extending in the direction of rotation formed on the main pole, and between the stator pole teeth, a permanent magnetic circuit is provided, by means of which circuit the rest position of the rotor is determined during the unexcited stator condition.
