Possible simple magnet motor

[vincent68]

Thanks for the post
I understand what you mean but this unit has no contacts on the disk. The only thing rotating it is the force from the magnet.
Thanks Vince

It's possible it works just like the power"reader" in most power installations in houses. There a disc is spinning faster as the powerconsumption is rising. An alternating magnetic field is crossing a disc of aluminum, and then it rotates and activate the kW/h digits ()

Hi,

Are you aware of this idea from Stefan:

Some years have passed I have not heard any positive results, Stefan?

Unfortunately it does not work this easy way.
These superimposed  fields are only 2 dimensional,
but we need a 3rd dimensional component to get anything
rotating.
So we need to find a way to get more than 2 fields adding up.

If we only would have a FEMM 3D we would find a working solution pretty soon...

Regards, Stefan.

yes this contact are driven (with gear) from an contactless diskmotor (disk can be copper or aluminium.
this is exacly that what you have in your power-reder (deutsch : Stromz?hler Verbrauchsmesser.)

So 3 fields should do? I understand that we so far got to enforce the 3rd dimention by adding external power...

I understand that the device you're quoting never will work, but I don't understand why the device in the initial contribution in this thread shouldn't - is it still 2 dimentional, I understand it won't work. Anyway, one have to learn the hard way - building the device and check it out

I'm quite convinced that I have to make a "virtual magnetic pole" in the center of the vertical magnet in the initial drawing, because the magnetic fields from the disc magnets are forced away from each other causing the device to misfunction.

I have now however tried the device just by fastening the bar magnet to a card board just to see if it is pushing in the desired direction - which it seems to do. If it works as a rotating device, I'll probably find out

I'm quite new here: What is FEMM 3D?
