1. A circuit arrangement for a stepping motor, whose stator windings (L1, L2, L3) are each connectible to and disconnectible from a constant-current source (10) by means of a thyristor (Th1, Th2, Th3) arranged in series with the respective stator winding, characterized in that a diode (D1, D2, D3) is arranged in series with each stator winding (L1, L2, L3) and a capacitor (C1, C2, C3) is arranged in parallel with each series arrangement thus formed, the charge on said capacitor causing the previously turned-on thyristor to be turned off when the thyristor associated with said capacitor is turned on. |
