Abstract

PURPOSE: To prevent the variation of gain, etc. of motor driving circuit by supplying to motor coil a signal amplified for pulse width modulation means in accordance with signal level detecting the rotation position of rotor.
CONSTITUTION: The output signal of the rotor rotation position detector 4 is applied to the operational amplifier 10, and then its output signal is put in the comparators 21 and 22 to make pulse width modulation by the output signal of the trianglar wave-generating circuit 23. The sigbal d is inversed by the polarity inversion circuit 24 and then supplied to the transistor 14a of the power amplifying circiut 11, and also the signal e is supplied to the transistor 14b and thereby the transistors 14a and 14b undergo alternate switching operation according to the pulse signals f and e. And, the signal e is given through the integrator 25 to the polarity inversion circuits 26a and 26b to drive the transistors 15a and 15b of the power amplifying circuit 12 and thus control current flows in the motor coil 2 through the low-path filter consisting of the inductance 27 and the condenser 28.
