Abstract

PURPOSE:To eliminate the increase of a starting current over the prescribed value with a simple structure by interrupting a power source for a DC motor in accordance with a signal having the waveform of a preset pulse. CONSTITUTION:A pulse train 8 of time interval determined by the power voltage and the set maximum current value is applied to a switching circuit 7. The circuit 7 repeats the connection and the disconnection between a DC motor 1 and the power source in accordance with the pulse train 8. In this manner, the current at the time of starting the DC motor can be suppressed to low value.
