on video 4000 watt universal motor speed control



How to make a universal 4000 watt motor speed controller at home. This video contains complete circuit diagram and step by step procedure for you to better understand and realize it.

It is a transistor based circuit involving voltage divider technique for smooth output voltage control and for this reason it can not only be used for universal motors but also for your DC motors, dimmers and charging your batteries.

You can easily adjust the output voltage according to your battery needs and then charge it safely. Full demonstration of everything provided in the video. Remember that the greater the number of transistors in parallel, the higher the power rating of the circuit. . The maximum current-handling capacity of this circuit is 36 amps since I used three transistors of 12 amps each, which together makes 36 amps.

The maximum voltage handling capability is 400 volts, which makes the circuit really powerful.

Although there is a Glitch. The maximum power dissipation capacity of each transistor is 100 watts making it a total of 300 watts and beyond that the circuit will be damaged.
