Run 12v 120 Amps Car Alternator as Brushless DC Motor with 500F Super Capacitor & BLDC Controller

In this video i will be converting this 12v car alternator into a high speed brushless DC motor and power it up with a super capacitor pack . I will also be using a no hall sensor type of BLDC controller and for powering up the rotor or field winding I am going to use a 500 farad 2.7 V super capacitor and a 12 volts UPS battery the current rating of the alternator is 120 ampere.

I was just telling my nephew how a alternator is nothing more than a BLDC and now I can show him! Thanks Mr. Electron!

Wow, I'm stunned at how long that capacitor can hold a charge and how much current it puts out, awesome cap.

When you change the field winding voltage, you change the field strength, and therefore the KV of the motor (KV is RPMs per volt at the armature). A low field winding voltage results in a high KV, which means the motor will turn very fast when the armature is operated at 12 volts, but there will be less torque available at the drive shaft. If you use a higher voltage on your field windings, you reduce the KV of the motor, so it will turn at a lower RPM but with greater torque. You can think of the field winding voltage as acting a lot like an adjustable gear ratio for the motor. If you were to use this on a go kart or something, then gradually reducing the voltage to the field as you accelerate would allow you to gain higher top speeds, without sacrificing the amount of torque available for accelerating from a stop or at low speed

Will that have strong torce ? Strong enough for an electric bike to do 60 or 70 mph?😊

Thumbs up for no music. Who was just waiting to see that clip fly off? Cheers

[ireneoyu]

Good idea interesting
Can you supply us all the
accessories & the instructions how to fixed excluding alternator ? And how much / set

Superb work, very nice experiment done

[junioralumbi]

Est-ce que en courant continu, un alternateur peut il démarrer sans contrôleur ? Congo !

[AnonYmous-cfci]

I must say that i'm impressed by your videos, so far. Good work!

[joserobertoerico]

ola amigo eu sou do Brasil, e gosto muito dos seus videos. Sempre com ideias inovadoras e muito interessante...Parabéns continuo sendo um dos seus inscritos..eu como técnico em eletrônica sempre renovo o meu conhecimento e você faz parte disto...obrigado.

Nice work but have questions if you give load on alternator how many take Ampers? Please can you help me i want use this idea in project please reply and so thanks

[messygaragetinkering]

If i increase the voltage to the field windings, would this setup (without the capacitor) be strong enough to start a Honda G100 2½ hp engine?

[edbakelaar]

Neat, simple idea. I like it. It would make a great science experiment for my kids science class. My question; what is its power? Can it do any useful work or is it simply a demonstration exercise?

[esnifan]

Me encanto este circuito genial canal saludos desde argentina!!

[TruePatriot]

Question is what kind of amps would there be under load? Spinning it is one thing but under load thats a different story.

[franklinpatrick]

Wow you are too intelligent. How long can it run until the battery becomes too low

[Alrukitaf]

I’m not sure about the role of the super capacitor. It is storing charge, which is what capacitors do, but what is the stored charge doing as it discharges into the motor? One would think any stored charge is dissipated into the amateur windings and once its discharged there’s no more charge left.

[gregstafford]

Do you need to charge the capacitor? does it charge the capacitor while running from the stator windings?
