Title: Magnetic Wankle Motor
Post by: babieintown on August 19, 2008, 12:42:34 AM
Hi guys
I come to this forum so late
and found out i cannot understand all of the threads.

I'm interested in the magnetic wankle motor. But when i search on it
i found that there is a rotary wankle motor too.
Are these two thing related in anyway?

Besides i read the old threads in the forum, and found some said about the energy to make magnets are 10-20 times the overall energy that magnets can give in their life before they demagnetized. So i wonder, is there anyway to keep magnet magnetized forever so we can harvest the energy from them until we get back the energy that used to make the magnets and reach the real OU after that point?

Best Regards

1) The Rotary Wankel and the Magnetic Wankel have nothing in common except the name.
2) Magnets don't get demagnetized when being operated in attraction mode so this is the least of your worries.

Hi Ergo

Could you give me some resources that explain about preventing magnet from demagnetized by operating in attraction mode
and is it possible to to keep imagnet magnetized forever? if yes, how should we  take care of our magnets.

I'm still little paranoid...before i invest some of my money  :D
Hope you understand  ;)

Babieintown, I have read a few of your post and like most of us it seems you have a lot of questions and have a lot to learn. I have a feeling you have a lot of reading to do. Here is a link to a great site that explains magnets and magnetism. I think it will answer a lot of your questions. Read it all! I did several times when I first started looking into this stuff.

I think you will find that neo or most permanent magnets don't actually loose their magnetism, but they become internally aligned magnetically, forming a closed magnetic loop within the magnet itself by physical shock (striking the magnet), or heat or a repulsively strong enough magnetic field (with velocity) to overcome the strength of the pinning material in the magnet.  The "pinning material" that holds the magnetic particles in place looses it's grip on the magnetically aligned order of the particles and they then seek to align themselves with the closest, strongest source, which is each other within the magnet.  This forms a closed magnetic loop which emits no magnetic field externally, so the magnet appears to have 'demagnetized'.  If this happens to only part of the magnet, the magnet is only weakened since only some of the particles have realigned internally and others stayed aligned with an external focus (original magnetic alignment).  So the particles don't actually demagnetize, but become realigned in an undesired direction.

The right name should be Wankel, not Wankle.
This difference will affect your search results.

Here is an old thread about Neodymium magnet properties. Very enjoyable.

Honk is a tad self effacing. The important discussion on this idea starts here:

Have a visit.

Thanks a lot Honk  :)

Now i try to develop the mathematic model to find out the possibility of the motor
which i hope it to be useful to analyze all the possibility of the magnet motor before we risk
our time and money.
Unfortunately, I cannot find any practical formula to calculate the force between magnets.


Can u please tell me a formula that predict the force if we know angle of two magnets, strength of magnet (Tesla), and distance ?
And how to calculate the force of the rotor and stator while there are more than one magnet on stator that react to the rotor magnet?
Can we integrate the sum of each force and how?

More, i found some useful about magnetism and electromagnetic for beginner up to 50 books
I will post the resource if anyone needed.

Lucks

I have used this very good force calculator.
http://www.magnetsales.com/Design/Calc_filles/PullAndPushBetween2RectMagnets.asp

You just input the grade, shape and distance between two equal magnets to calculate the force.
In a magnetic wankel the distance between magnets is a gradient slope.
This means you have to calculate the distance from both sides of the rotor magnet to the opposite stator magnet and
then you subtract the lesser force value from the greater. Split the result by two and you have the gradient force.
Nice and simple.

Sometimes the magnetsales calculator have a long response time. I guess there is a lot of people using it.
