PM homopolar motor concept?
« on: April 05, 2018, 04:25:21 PM »
Hello. Long time since I've been in here.


I have played with homopolar motors, and tried to understand how the Faraday paradox comes into play when using a conductor, battery, nail, and a neodymium magnet.
The charged particles (electrons) is set in motion, electric current, which exsert a force perpendicular to the magnetic field and the motion of the electrons. This cause the homopolar motor to spin.
Lenz force.


Do this also apply if the wire (electromagnet) is replaced with a permanent magnet that is "merged" into the rotational disc magnet? Here is an idea how to merge those two magnetic fields perpendicular and into eachother.
Have this been tested before? I find it hard to find such thin strong disc magnets, and a comb-shaped stator magnet. Magnet with slots that fits between the layers of disc magnets.

@Low-Q:

Not sure what size of disk-magnets you are hoping for, but have you seen these?
https://www.kjmagnetics.com/proddetail.asp?prod=RX032
Or
https://www.kjmagnetics.com/proddetail.asp?prod=RZ0X84


Those "comb-magnets" will be challenging to find . . .

There you go! Thanks! They will do for the experiment.
I have lots of rectangular magnets. Approx 4mm wide, 50mm long 1,5mm thick. Printing a structure that keeps them in place would be a nice option.
Using a grinder to make those slots will probably destroy the magnet.
I have lots of 1 inch disc magnets, but they are too thick, and without the hole in the middle.


I try to keep the "slotted" magnets as close to eachother as possible so they, in a better way, can act as one whole magnet. If the spacing is too far, the magnetic flux will just jump right back to the S-pole on each separate magnet, in stead of making that nice large magnetic loop, and compromise the experiment.


I do not have great hopes, because I suspects that the electron flow through a wire is more likely to follow that large loop. The multiple electrons that circulate the atoms in a PM will not follow the same large loop as in a conductor with electric current. I think it is here the whole difference is between an all PM homopolar motor and a regular homopolar motor.
However, both ways produce a magnetic field that is very similar, if not identical, to eachother, and the electromagnetic field through the conducting magnet is produced by that directional electron flow. And therfor cause the Lenz effect and the spinning motion.


While keeping myself om very thin ice here, I suspect that the spinning electrons in a PM is "scewed" when the current flow cause the perpendicular electromagnetic field, and like a gyroscope you try to change the angle of the axis, will force motion of the axis that is perpendicular to the direction you want to push it. In a homopolar motor, this will cause the motion that is perpendicular to both the direction of electronflow and the magnetic field through the rotating disc magnet.


It's worth a try. Now I must order some of those magnets.

Yes I will. So easy to make structures for the statormagnets with 3D-printer, so this phase should go pretty smooth.
I noticed, however, a much thinner discmagnet on that site. Only 1/32 inch (0.8mm) thick N52, but with no hole. However, printing out parts that center these discs should go fine. Just let the"rod" be a part of a printed thin one layer (0.3mm thick) disc that is applied with a thin doubble sided tape. Total thickness will then be 1.4mm instead of 3.2mm (1/8 inch). I need thede stator magnets to be as close to eachother as possible. Increasing the thickness by adding more statormagnets side by side will help too.

I make a few of these green pieces to keep the thin discs apart.
Magnets are the grey/white between them.

In your first post is that diagram all magnets with the red and blue indicating the magnetic poles?

Yes sir. It is :-)
