  • Damped stepping motor for the driving of a measuring mechanism, particularly a roller counting mechanism having a control circuit arrangement
    Patent number: 4562395
    Abstract: A damped stepping motor (1) for the driving of a measuring mechanism is acted on with approximately rectangular pulses by a control circuit arrangement having at least one amplifier (amplifier-transistor 5) as controlled switch. These pulses are obtained from measurement pulses. For the damping of the noise of the stepping motor and the measuring mechanism connected with it via a transmission, the amplifier forming the controlled switch is connected by a delay of the first order (capacitor 9, series resistor 10), so that the edges of the pulses fed into one coil are rounded.
