Closed-loop speed control system with voltage feedback

Another method is to extract
the signal related to the back electromotive force of the motor from one end of the motor , amplify and average it and then use it as pin 3 input. Use the drive output
A as a single-ended output and connect an external TIP42 power transistor to drive the DC motor and increase
the control power. These two examples illustrate
the use of the MC33030 in single-steering motors.
