The stepping motor for pulse-controlled electronic clocks is provided with stator laminates of unsplit sheet metal, which have recesses for the rotor at the open ends of the stator laminates. In order to create a pulse-controlled stepping motor which can be assembled at a low assembly cost and requires only a low drive power, the core laminates (1) of the stator have allocated to them externally attached additional laminates (2) whose tabs (21) and steps (22) cover the air gap (11) of the core laminates (1) and whose end opening (23) is smaller than a quarter of the circular cut-out which holds the rotor. In this case, the drive coil is advantageously pushed over the one limb of the stator, after said stator has been bent laterally. <IMAGE> |
