#alternator #generator #Charging In this video we are going to have a look at how alternators generate electricity to power the vehicle's electrical needs
I just saw a video that said the interlocking claws were not magnets. They become magnets when electricity is sent through the copper field windings. I'm confused because you just showed they are magnets but there wasn't any electricity flowing through the field windings.
They will get magnetized only when there is current flow through the rotor winding! The discussion is presented here assuming there is already current flowing through the coil and the claws are magnetized. @ 10:26, 11:33 and 12:18 time on the video, that was mentioned.
@@TheAbJGarage I see! At 10:05 the piece of metal that looks like a coin is actually the magnet and that’s why it stuck to the rotor interlock claws. Those claws only become magnets when electricity is sent through the coiled wire wrapped around the iron core in the rotor.
The rotor coil current direction is fixed! and hence one end of the coil becomes north and the other becomes south when current starts to flow through. The pole claw attached to the north pole end becomes north and the one on the south side becomes south pole. If interested we can use the right hand rule to determine the polarity of the coil when magnetized. Or one can use a needle magnet on exposed rotor to identify which end is north.
I enjoyed the explanation of the copper wire... Understanding that help me with the rest.
Thank you very much!
Super method to explain. Thanks
Good Sir 😊
Thanks👍

One more question. How do they get each individual claw to be north or south pole since the claws aren’t magnets but just metal?

@@TheAbJGarage Got it! Thanks a lot for the clarification.
How much AC volt does an alternator creates before converted to dc?
Good sir
Not sure, I think 110.
