Pemox
« on: July 14, 2011, 07:24:07 PM »
The Pemox is a new open-source-project.

Currently it´s only theory, but - as far as I can see - it has really good chances of success.
The Pemox is a magnetic motor, which - WITH ORDINARY PHYSICS - should provide more power than it needs.
Because this is an open-source-project, everybody can build a Pemox.
Until now, I did´nt found a mistake - but perhaps anybody will find a reason, why the Pemox can not work?

I´m very tense upon your opinion.

Brilliant design! Now let's think about the possibilities to make the design more modullar - the possibilities to use E or C laminates. How about E laminates? These would look like in the picture attached. However, I'm not sure how it would influence the field. Could you make some simulations with the cores connected together without a gap ? This would simply things a lot. For example you could use just coil bobbins and not wind a coil directly on the core. And of course use just standard E cores with a little of modification.

Don´t make it too complicated.

The cheapest way is, take a transformator - put away the coils - and cut in a circle for the rotor.

A better, but more expensive way is, to let it make from a company which can cut it with a laser, like (e.g.) www.elektrobleche-weissbleche.de

A simulation without a gap makes no sense, because the gap between rotor and stator is always there...

The best would be coherent laminates like this:

Hi,
First of all, where can you find laminates like the ones you drew ? I've no knowledge of such laminates on the market. Secondly, I didn't mean the gap between the stator and rotor. I meant the gap between two laminates - the ones I've drawn - the E type. And it won't make it a more difficult solution, but the easier one, as with E type lamianates : 1. they are easy to get, 2. easy to assembly, 3. easy to change the coil. It would look like in the attached picture. And this is the situation, where I would like you to do the simulations. I think, that as for the simulation you would have to make a minimal gap between the E laminates, as in real life there would always be a small gap between them (I think ?).

By the way - in the transformer you typically have the E type laminates ;>

Sorry, of course, you´re right.
There are no related laminates like I mean. And of course, it´s difficult to make a coil around it.
I meant - it´s easy to take a transformer and - with it´s overlapped laminates should the gap between the laminates not really become a problem.

The cores, you linked, looks great - but take care of welded joints, may be, that´s worse than an air gap.
It´s a good idea to take only E-laminates - and a simulation shows not a great difference, as you can see attached.

But I think, the greater problem will be the rotor - not the stator ?
Have you any idea, how to make the rotor?

Found also this one:
http://www.sz-wholesaler.com/p/505/531-2/mini-motor-rotor-82-158119.html

However, there is not much place for a coil in this stator. The rotor also cannot be used unfortunately. Have to think about the rotor's design for a second... or two ;)

For sure it would have to be laminated like this one:
http://china-rotor.en.made-in-china.com/product/XoNEDLxCnSWY/China-Motor-Rotor-Core-Distributor-YC0003-.html

but without the middle part - there has to be a non-magnetic separation between the leafs. Not easy ;/

Also, as for the stator laminates, remember to use only Cold-rolled non grain oriented silicon steel (CRNGO). The problem is, that very often in the transformators they use CRGO laminates, as GO (grain oriented) is anisotropic, offering better magnetic properties than GNO (grain non-oriented) in one direction. As the magnetic field in inductor and transformer cores is static (compared to that in electric motors), it is possible to use GO steel in the preferred orientation. But we don't want it ;) We want GNO.
