Title: New to forum - here's my idea\design - comments please.

Hi,

This is my first post... been reading with interest on various mag motors, mainly the thread on the Torbay one.

I've got a design which is really simple and would like your feedback. Maybe it's too simple, but then maybe that's why it might work, who knows!

Looking at the diagram the rotor should rotate clockwise. The outer round magnet would be static with a bar magnet with a central pivot which would allow it to rotate (the rotor). My theory is this, the attractive force at x would be greater than at y (due to the difference in distances from the outer magnet) which would exert greater pull at x which would cause the rotor to rotate clockwise. The opposite happens at the other end, whereby the repulsive force at a is greater than at b again causing the rotor to want to rotate away from the outer magnet, in a clockwise direction.

The two steel plates attached to the sides of the rotor magnet are to help shield the other surfaces from coming into play.

Does that make any sense?

Please comment, you guys seem to have a wealth of knowledge with these things so looking forward to your replies. I hope the picture comes out ok.

Thanks, Phil-UK

This concept is in complete equilibrium, hence it won't move at all. It should spin freely, due to the fact that the magnetic forces cancel themselves out, but in effect what you have done is create a rotary magnetic bearing.

What you said about x,y and a,b is partly Ok, except some things...
This is not mean it works as you think. Because you not include all the things what happens. As gn0stik say, it's in total equilibrium.

The reasons:

The force at x is greater than at y, but what is the direction of the force? It points to (almost) 9 o'clock position. In this case it works something like you take a rope and knit the rotor to the stator. When a magnet attracted to another magnet or steel, it doesn't want to move any longer at all. It want to stop forever in that position until a greater force doesn't take it free. This is important about magnets. They always want to reach balaced status.

In the other hand the force from the ring magnet is always points in radial direction at all points of the ring, so on the right side the difference of the distances don't change too much, it is also repelled clockwise and counter clockwise at the same time. The direction of the torque is almost points to the axle of rotation. No real torque appear, and the forces on the sides are totally in balance.

The thin "shield" also doesn't help. It weakens the force of the magnet (takes flux), and works (become) as a weak magnet, too. So it adds a bit repulsion in the attraction side, and adds a bit attraction in the repulsion side. Ferromagnetic materials are not real shields. They take the flux from the magnets.

Anyway it's not a bad idea for start, I also checked it in my mind once before. Simple things are good.

I think what you want is possible, but not in this way. It needs much more well baked mathematical / geometrical calculations to do it.

Best Wishes,
Greg
