Inside a Car Alternator Green Energy Generator Brush Reinsertion for wind turbine RPM

Brush Reinsertion trick. Many people wonder why free car alternators off the shelf are not used for wind turbine electrical generation. The Windings are very thick wire limiting the amount of wire turns per coil around the stator. Car engines have a lot of torque and idle RPM. The pulley on car alternators are usually much smaller that the engine’s crankshaft pulley. This allows for much higher RPM in the alternator. Car alternators do not have permanent magnets in them. They use an electromagnet to produce the flux in the coils. They need to be energized or excited. Car alternators have a high level of cogging.

    looks like that his haved find out what the alternator is 😀 The people that thinking that everyone around so stupid is shows the dramatical substance of the stuf between theyr years.

    I used to watch this channel ONLY to check out the FINE Chick here.
    But now, a few hundred moons later, The Chick is getting FAT and losing her looks, (getting ugly) So…..
    not even worth watching the NON-SENSE of this WANNA be "Scientist" Dan Rojas
    They are REALLY two washed-up former TV actors, (former AFTRA union members I believe he said……..)
    So, as an actor he can "ACT" the part, like he knows what he's doing….. LOL
    But WE the people who are real Scientists…….. KNOW BETTER!!!!
    LOL indeed!

    BTW Today, I wound up here only by accident, not that I meant to watch this stuff…….
    This stuff is only good for elementary-school kids……..
    (even middle-school is too advanced for this bullshit)

    You need to either change your oil or adjust the lash on your cam followers. Lots of valvetrain clatter going on. Some is expected but yours sounds excessive.

    Dan I started watching your videos a long time ago, you've come a long way from the parabolic lenses, good job, I really would have loved to see you finish this alternator into a turbine regardless of the induction needed just for educational purposes.

    Hey Dan! Great video. You explained exactly what I wanted to know. I hope you have bought a new car. That one sounded so sad and sick. haha. Look forward to seeing more from you.

    hola amigo. es posible ponerle un alternador más a mi automovil con imanes de neidimio con la finalidad de alimentar una celda de electrolisis de agua para generar hidrógeno que el motor va a combustionar?

  7. ben lawton says:

    That looks like it has a built in voltage regulator so the winding would control amps not volts.

  8. thedoaba says:

    did you destroyed brand new alternator for a video?

  9. David N says:

    great video, Dan, nice quick cuts get right to the point and show visually the theory. Bill Nye would be proud.

    hello, dan, like the way you explain things,,your a great teacher….also got a great help,wife…
    use more the words ,"thankyou", n "please" to public…help me??
    can you explain in a video how ?? the current flow in the alternator the on n off or low n high volts to regulate the magnetic
    of alternator that goes to the battery… in the mud with this problem ,,i burn my regulators in tests..i have done..
    help,,,,need $$$ let me know….thankyou,,lots…to you n yours…

    didn't you play in Three's a company you look like him you sound like him you must be him

  13. tom flemington says:

    dan, would it be possible to build a wind turbine based on an alternator, and use a small brushed dc motor driven off an integral drive shaft to supply power to the field coils, thereby increasing load on the alternator as wind speed increased? second part of the question is how much current do the field coils require to energize fully?

  14. mike sambaluk says:

    So to use a alternator as a wind turbine I would need a small solar panel to excite the alternator to get power back to the house? How many Watt panel would I need? I have some small 6"x6" panels for night motion lights

  15. Horacio Hidalgo says:

    I didnt get it did you change anything in the alternador?

  16. Ross Gordon Wensor says:

    Great video thanks

    I would like to see if the field could be used as an over speed control. As RPM increases the increased alternator output could be fed back to the field, increasing drag and slowing the RPM of the system. This would also allow generation at lower wind speeds by limiting field strength. It might be as simple as using a pot as a voltage divider to the field. I have never had a reason to check the field current on an alternator but it shouldn't be too high. You could not use the regular to the batteries as this would allow higher RPM's if battery voltage was low.

  18. Pieter van Niekerk says:

    As a matter of interest … car & truck alternators are designed to deliver a fixed wattage ( the rotor is designed to saturate, this automatically limiting the output current, the number of winding turns limit the maximum output voltage. The regulator just limits the output voltage to prevent the battery from overcharging.

    i have one a altnator can i use a it on a inverter
