Magnet motor in Argentina

[treb79]

anywho, my wife is having contractions so i am headed to the hospital in a minute. will be back in a few hours to check on the thread. good luck with all  your replications! Smiley

It's either your first one then, and you've no idea whats coming. Or it's the latest of many, and you're an old hand at it. At any rate, best of luck..... and with your motor.

question - i have been storing my magnets stuck together (s/n natural atraction, so on) ...... will this hurt the magnets? i am not familiar with demagnitization at all.

thanks

Hi Danny,

Actually, having magnets stuck together in attraction is good for them and will help to preserve the field strength. That is why most horseshoe magnets come with a metal keeper bar across the legs to keep it from demagnetizing.

@Tao

What 3D simulation software are you using? I have Maxwell3D but am also looking for other packages to compare results with.

One more thing, to everyone, the idea of degaussing the magnets isn't really that much of an issue as long as you use matched magnets for the stators and rotor like ceramic 5s, ceramic 8s, NdFeb magnets. They are quite prone to not degauss. Look at Bedini's clarifier device, it has two ceramic magnets glued together in a repulsion S<->S and they don't degauss themselves, because they have LIKE fields.

Anyway, good work.

Yes, but the problem is when magnets have not got an EQUIVALENT magnetization (rotor-stator) and this is the case, and the best case to avoid an strong resistance to push down each stator. As large is the difference between rotor-stator magnetization as large is the net torque you have to push down each stator. The problem with FEMM is to simulate z components (this case). You can use other point of view of magnets (stator and rotor) to view it or test it with a simple experiment. If stator magnets are similar to rotor the force observed is very very strong and even "moves" the rotor when the stator is forced by hand, that is, it is greater than torque in rotor and in this case the devices will not work or... there is a special parameter combination to avoid it: distance between stators, between rotor-stator, etc.

Springs can help to push down, indeed I thought so before, but then we will have another problem to lift stators before rotor reaches it. Due to no linear model, maybe it is possible to use a different behaviour for lifting and pushing ... There is a very nice diferential equation to solve or so many test to do ... but it is the science challenge 

Best wishes to Silverdragonrs  . Good luck.

Yes, it might work, if in a Rotor we'll have one magnet (for start) with repulsion polarity with the Stator' magnets and pushing guide in the front of it, which will lift up one Stator's magnet and create disballance of forces. Rotor moves because of this disballans and pushing up another Stator's magnet and so on...

'...just as you described Torbay has already done'.
-Tao, how sure you are? The magnetic field is a 3Dimensional. When Stator's magnet goes up something has to put it down in the row, after Rotor passed by. And it needs an energy to do it. At least in my Stator magnets pops out from the row, and I need to do something to put it down.
