A practical circuit using armature control to achieve motor speed control is presented in a control system using a DC servo motor, a power amplifier with a ± 2 4 V output voltage. The characteristic of this circuit is that by adjusting the given voltage value, a large voltage sufficient to drive the motor to rotate is obtained at the output of the amplifier. Has some practicality
