Permanent magnet motor

[ayeaye]

(  Of course that  wire should probably be replaced with either a coil ,  or something similar to multiply the power  )

Coil cannot be used in the Faraday's homopolar motor, it doesn't work. You should think things more through before you come up with ideas.

( I don't actually know if  the idea I'm posting here,  has already been tried before,  I would just assume it has  )

To make a  Donut-Magnet  with the  magnetic-field  rotating around the circle of the  toroid,  could they not  just use  another  wheel  with very-very-powerfull   SEPARATE  magnets set on it,  and then  just spin the wheel at the required speed

OR

The same process I have typed above,  but the SEPARATE  magnets  would be     'SEPARATE extremely-powerfull Ring-magnets  THAT ACTUALLY COMPLETELY ENCIRCLE the curved-pipe that is the  DONUT,

I think you have to, but not in this thread. This thread is about permanent magnet motors, that is motors that have permanent magnets only. You can write about any ideas or experiments about these, in this thread.

That is, the problem is how to make any of these, at all. And there may be some things yet to be tried, before concluding whether making a continuously rotating permanent magnet motor is possible at all, and whether it is a way to go. Anyway, it seems to involve some high voltage devices such as stepping up transformers or welding transformers, and high voltage capacitors. And some rigid mechanics equipment, such as fastening mechanical components and bearings. An equipment which is not likely very cheap any more, and thus it may not be easier any more than experiments with coil, and for that reason not the best way to go. Likely more easy to understand than electronics though, i must admit, even the most simple circuit is not exactly simple, as it consists of components that have a complex behavior. But most likely not cheap, and for that reason such experiments may not be affordable for most of the people.

But, there has to be a kind of road map for research. So i think it is, when it appears that the permanent magnets are not a way to go, switch to coils and induction. Or when one cannot afford any more the costs of doing more advanced experiments on permanent magnets. This is also why i said, try coils on different cores, such as pieces of iron pipes, or maybe just a thin winded iron wire, and see whether there is any effect on permanent magnets, because the circular magnetic field in the cores of such coils, should be exactly the same as in the circularly magnetized permanent magnets. This should be affordable to do i think. But, a good coil has 1000 turns, and, the core should be either painted, or covered with a *transparent* plastic.

Guest1289, but what to do is rather your problem, because you decided not to go to electronics, because it is too complicated for you.

Here's  the  diagrams

DIAGRAM 1 ( below ) : -   To make a  Donut-Magnet  with the  magnetic-field  rotating around the circle of the  toroid,  could they not  just use  another  wheel  with very-very-powerfull   SEPARATE  magnets set on it,  and then  just spin the wheel at the required speed

OR

DIAGRAM 2 ( below ) : - The same process I have typed above,  but the SEPARATE  magnets  would be     'SEPARATE extremely-powerfull Ring-magnets  THAT ACTUALLY COMPLETELY ENCIRCLE the curved-pipe that is the  DONUT,     and then  just spin the wheel at the required speed
      Obviously,  this option in  'DIAGRAM 2',   would need some method of holding the  Donut-Magnet  while the rings are rotating around it. 
            One way could be that the   magnetizing-rings   would not totally  encircle  the main-ring,  to allow the  main-ring  to be anchored to something.   
            Another way could be that  if the  magnetizing-rings  would be  ELECTROMAGNETS,  then maybe they could actually  LEVITATE  the   main-ring which they are encircling.

You mean, radially magnetized ring magnets, around a circularly magnetized donut magnet, to both make the donut magnet to rotate, and hold it in the air? Yes theoretically, a pole of a magnet and the circularly magnetized magnet, should repulse. So not a bad idea really, if only an external magnet had any effect on a circularly magnetized ring magnet (donut magnet). Also a weak point may be, that a donut magnet is thick, but circularly magnetized ring magnet may have to be thin, so that there maybe is some circular magnetic field on the surface. Well, another weak point, when the ring magnets are around the donut magnet, and the donut magnet rotates, then it is very difficult to extract energy from the rotating donut magnet, anyhow. But, when the donut magnet stands still, and the ring magnets revolve, then it's easy to extract energy from the revolving ring magnets, just by having a coil near them. Well, that again cannot be done, maybe they should be a kind of u shape magnets...

Well, i remember somewhere a similar idea. Like a donut shape pipe, and likely a radially magnetized magnet, moving inside that pipe. But as much as i know, no one has yet made such thing.
