Abstract

A circuit arrangement for rate indicators with a stepper motor counter in front of telephone subscriber installations using two windings, characterized in that the windings 1 and 2 of a stepper motor are connected in series in opposite directions, and the capacitor (c) is connected directly in parallel with respect to the winding (2), because the winding (2) of the stepper motor acts as direct negative feedback with respect to the winding (1), nullifies the field of the winding (1) and therefore brakes and ends the first half-step, because the current for the second half-step of the stepping motor can be losslessly connected to the winding (2), and because the beginning of the connection of the power supply and storage voltage capacitor (C2) is made in the direction of the Zener diode circuit (D2/D3) in the conversation circuit by the rectifier bridge (D4) acting as a guide polarity and reverse current blocking.
