Question: the diagram says that you must connect the capacitor in parallel respecting the polarity at the regulator output, but in the video you connect it by reversing the polarity ... why?

You can use vaccum cleaner empeller for water pump motor.

[@martinbobak3009]

Just think about it

[@icghost2]

Once off, those motors are generating power that's feeding back into your transistors. I would suggest that the proper diode on your output would provide some protection, significantly prolonging reliability and operational lifetime - thanks for the video!

[@quevicular]

I was wondering that to myself.

[@petersack5074]

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.

Question: whats valor of 4th transistor?

[@simonvann7270]

Mr Electron, The 4th transistor is not listed in you build list, which one did you use? Great videos 👍

[@simonvann7270]

Anyone know which ⁴th transistor will do this job???

[@jjhack3r]

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]

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".

[@VictorUsiwo-gn2cx]

How do I get the full complement of the DC/Ac universal controller and what is the number of the Fort transistor that you call the driver transistor

[@satyajitbhadraroy7723]

If we reduce the speed of an universal motor (lets say washing machine motor) this way, does it reduce the torque of the motor also?

[@carmelpule6954]

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.

Hello Mr. Electron. Can you create one video for works at 220v ac please. thank you very much.

[@faus040459]

Hello, what is that type of capacitor called and where can they be found? Is it electrolytic? What if it was positive? On the other hand, is the fourth transistor the same as the other three? The potentiometers that I have reduce the speed but little by little the engine is increasing its revolutions by itself and I want to try the one you explain if this does not happen. I am looking forward to your response. Thanks

[@danielfranchette5547]

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.

Hi mr electron! I really love ur video very helpful ❤️ i have a alternator from a zusuki multicab. How can i run it as a motor direct from 12v battery without using speed controller? 🙏🙏🙏❤️❤️❤️

[@danielfranchette5547]

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.

[@linsonkp7261]

Thank you so much bro.....really good.....

[@TheRealFobican]

Now this is the type of controller I would like to swap out the digital controller in a tesla if not generally in any ev for making the car even better than originally.

[@dkdanis1340]

Are you serious how in the world would this be better than super engineered tesla controller.

[@TheRealFobican]

@@dkdanis1340 it's not requiring anything digital that needs it's own power to power a motor eating into the power consumption which is not ideal for an electric car as it creates a bottleneck in performance and range. Besides it's something entirely else than what everything is transforming into in the present.

[@despiertahumanidad6715]

How about mr electron, is this speed control system suitable for use with brushless motors with three outputs? And if this is how it connects to your system, would you have to adapt it to the 40 Amp esc driver or is it not necessary? Thank you in advance for your contribution ... your video is excellent

[@danielfranchette5547]

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.

[@flojotube]

This is one of your best overall videos brother. Many of them are difficult to understand (why or how) things are happening, but here you made it easy while showing off a very useful tool. Thanks
