4000 Watt Universal Motor Speed Control - Make 120v RPM Controller DIY

How to make a 4000 watt Universal motor speed controller at home. This video contains full circuit diagram and step by step procedure for you to better understand & actually make it.
It's a transistor based circuit involving the voltage divider technique for smooth output voltage control and for this very reason it can not only be used for Universal Motors but also your DC Motors, light dimmers and charging your batteries.
You can easily set the output voltage according to the requirement of your battery and then charge it safely. Full demonstration of all that has been provided in the video. Remember that the more the number of transistors in parallel, more will be the power rating of the circuit. . Maximum current handling capability of this circuit is 36 amperes since I've used three transistors with 12 amps each, together making it 36 amps.
The maximum voltage handling capability is 400 volts which makes the circuit really powerful.
Although there is one Glitch. The maximum power dissipation capability of each transistor is 100 watts making it in total 300 Watts and beyond that the circuit will get damaged.

@danielfranchette5547 2 жыл бұрын

This type of drive concerns direct current motors. Universal motors are series magnetic excitation motors that can operate in direct or alternating current (motors that have the annoying habit of racing at low loads). Brushless motors are synchronous AC (three-phase) motors, this type of drive is not suitable.

1:30 you asked: okay, use that center hole where the impeller is, and place about a 6 inch funnel facing it, narrow side into hole. Put all this behind your grinder wheel, and attach the motor wires to the grinder switch. So, when you switch on the grinder, the vac sucks from the funnel end, into vac and into a hose into shop bucket, with cloth over top. I also use microwave oven magnets, on the grinder shroud, to attract filings. Njoy your creations, thankyou too much.

@danielfranchette5547 2 жыл бұрын

An alternator is a synchronous machine with alternating current, it is compulsory to have a frequency converter to control this type of machine as a motor. Car alternators have diodes that convert alternating current to direct current to power the car (unless yours is of a very different technology). In addition, they have an auxiliary magnetic excitation circuit that must be supplied in alternator mode but also in engine mode.

That circuit will burn if you use it at half power and actually use the motor. It needs to be pwm switched or else it wastes a ton of power as heat. All you made was a variable resistor... sure it "works" but it is potentially unreliable and wastes lots of power...

@johnbarry8185 3 жыл бұрын

In reality, it does NOT work on the A/C motors. That's why he kept raising the speed, instead of stopping in between anywhere. That's because it WON'T stop at a lower speed, it will "run away".

@carmelpule6954 2 жыл бұрын

As far as I can see that is not a speed controller but a torque controller which is not the same issue. As the output is taken from the collector of the transistors, then the unit is a current source with a high impedance output and not a voltage source with a low impedance output, hence it is a torque controller. If the output was taken from the emitter as in an emitter follower, then the unit would be a voltage source and hence it would be a speed controller where the voltage of the source would be balanced by the back emf of the motors. That is what we mean by speed controllers. The input voltage comes from a low impedance source, hence a voltage source must be balanced by the back emf of the motors being used. The sound suggests it is a current source controlling the torque. If those motors were fed from a voltage source the acceleration would be much faster. One should be careful when using a transistor as a current source and using it as a voltage source.

@danielfranchette5547 2 жыл бұрын

Here the transistors operate in variable resistance, they will heat up very quickly and the overall behavior will not be very stable (maybe your problem). This is not the right method for this type of application. A PWM command (see wikipedia) would be much more efficient. The capacitor is of the electrolytic type. Be aware of the danger of voltages greater than 50 V AC, 100 V DC.
