Energy From Permanent Magnets

[rukiddingme]

Hey everybody,

I came up with a design for a magnetic motor that might be over unity.

Could you all have a look and let me know what you think.

Thanks

Looks like a DC motor, with polarities reversed.

Do this in a circular configuration such as electric motor and there is less resistance to mechanical movement to overcome

I've made several piston type models before and they dont work for one very important reason. The explosion in the cylinder of a gas motor is tremendous to cause the piston to travel the 2 or 3 inches it has to move to turn the crank. 2 magnets repulsing or attracting each other, even with 500lbs of force, doesnt come close to the power of the gas explosion and the 'throw or travel' available from peak power of pm's is very short (1/4" to 1/2" tops on big magnets like your talking about. All this just makes it very difficult to create the force needed to overcome the movement needed to turn a crank.



Keep in mind I know very little. All I've done is a lot of experimenting and model building.

Yes, these pistons only move about 3 centimeters. There is no compression to overcome and very little resistance.

Yes, it isn?t as powerful as a gas explosion. The throw travel of the magnets I have are about 3 centimeters. I know this because I can feel it when I bring one of the magnets close to metal. After about 2.5 centimeters it sort of clicks over and the pull is almost irresistible to stop with my hand.

All this just makes it very difficult to create the force needed to overcome the movement needed to turn a crank.

Could be, I don?t know these things, that?s why I?m here. The calcs a professor did for me on how much kinetic energy you get from a magnet of 7100 gauss and a pull force of 231 lbs. came out to be 200 joules per magnet, that?s 400 joules per electromagnet. Seems like that is plenty.

Thanks for the information. Do you know the math on how to determine the kinetic energy you can get from a magnet of 7100 gauss and 231 lbs. pull force, as it approaches a metal target? I would like to verify those results.

Here are the magnets I have:

I have the same magnet without the NI coating. Very strong. The 231LBS of pull is flat against a 1/4" steel plate. At least thats what the Magnet Supplier tells me.

Thinner steel and distance make a huge difference in the amount of pull (proven by my modeling efforts). Sorry I dont know the math.

Didnt mean to discourage in any way at all. The only way to prove or disprove is build a model.

I don't really have the ability to build a model, but it is interesting enough for me to do a few experiments and get assistance to work out the math to prove the concept theoretically. I don't think I can be discouraged, I'm not convinced this will work. I am doing this as a learning experience which is only beneficial.

Thanks for the post.
