Abstract

PURPOSE: To arbitrarily vary the set speed of a DC motor by supplying the output voltage of a bridge connection to a feedback amplifier and inputting the standard voltage variable with the output voltage to a drive amplifier.
CONSTITUTION: A drive voltage e0 is applied from the output of a drive amplifier such as, for example, an operational amplifier 4 having a gain G for the bridge connection to the inverted input terminal and non-inverted input terminal of a feedback amplifier 5 having gain H in the relation of gain H>G at the voltages e1, e2 at the connecting points of the bridge connection. A standard voltage VS is applied from the terminal 1 to the non-inverted input terminal of the amplifier 4, and the output voltage of the amplifier 5 is applied to the inverted input terminal of the amplifier 4. Thus, the standard voltage VS is altered to thereby vary arbitrarily the set speed of the motor.
