Abstract

PURPOSE:To make it possible to control with high accuracy even if a speed motor is not provided by obtaining the voltage proportionate to the speed of a motor based on the terminal voltage of the motor and the voltage equivalent to the voltage drop of the inside of an armature. CONSTITUTION:The collector voltage of a transistor Q is equalized by a filter circuit 9, and a mean value E1 of the armature voltage is obtained. And, the voltage drop of the resistor R1 inserted into an armature 5 in series is equalized by a filter circuit 10 to obtain the voltage equivalent to the voltage drop IR of the inside of the armature. Then, the differential voltage between voltage E1 and IR is obtained by a differential amplifier 11, and the voltage proportionate to the speed of a DC motor is obtained. A comparator 2 compares the output voltage of the differential amplifier 11 with the reference voltage set by a speed setting 1, and the differential voltage is outputted to a pulse amplitude modulation type control device 7.
