i live in a small town . and there is a voltage problem . some times voltage drops . and some time icrease . when the voltage went down the tubewell motor is not work properly . the flow of water from tubewell become very slow . And In case of high voltage motor destroy . the motor coils damage due to high voltage . we made a manual regulator for tubewell motor wich provides us the fix voltages . But it is a manual regulator. we must have to change the cables to get required voltages . i want to make an automatic regulator wich give us fix 440 voltages in case of high or low voltages. so that the regulator control high or low voltages and give us the 440 fixed voltages automaticaly . so please some body help me . how to make an automatic regulator . please help me with diagram.
