Pulse Motor (Back EMF) 002

Demo of two coils where one coil energizes the other and repels a magnet that spins a disc. The second coil can be used to recharge the battery which energizing the first coil, this makes it very efficient.

And you just discharge X-Y number of batteries where Y is the lose of energy due to friction in your system let alone the loss of your inefficient human body pressing a button. When you figure this out I want you to push my car to work and back so I save gas and then not complain when you starve to death tryign to eat the same amount of food as you did prior. Basic 6th grade physics. FAIL!

Thanks for watching, but I am not pushing your car. I'll PASS you bye!

I having problems with coil, i think..

Try holding a compass by it...

Using back EMF to recharge a battery will actually -reduce- efficiency, because any significant current draw on the secondary coil will slow down the motor. You must convert kinetic energy to extract electrical energy, and this is why the motor would slow down. The reason it doesn't slow down with the LEDs attached is because they do not draw a significant amount of current. Ever try to turn an electric motor by hand with the coils shorted out? It's much more difficult than with an open-circuit.

I think you might find that the Flyback voltage is usually grounded, zero back.

But thats for the comment the later videos are better....

list of supplies and where to buy them?

[AccessNo]

After this, the world as we know it will never be the same again :))))))))))))))))) OMG dude you gotta be related to Nikola Tesla

do this in an elcetrik car
