Abstract

PURPOSE:To reduce the power comsumption at the time of low-speed running, by sensing the interval between the clock-pulse generations for a pulse motor driving signal, and controlling the current which is fed to the pulse motor. CONSTITUTION:The pulse motor 1 is composed of a rotor 2 and stators 3a-3d and excited by the one- and two-phase exciting method. A driving circuit 4 is composed of a four-phase separator 5 and switching transistors 6a-6d, receives the clock pulse signal which is inputted from a terminal 13, excites the stator 3a-3d sequentially, and rotates the motor 1. As a means to sense the interval between the clock pulse signal, is provided a retriggerable one-shot multivibrator 15, which sends out the output to a current limiting circuit 7 when the pulse generating interval exceeds the specified time length. Then, a transistor 10 is conducted, the current flowing in a transistor 9 is decreased, and the current at the period of low speed running is limited.
