The bearing motor

I think the fact that it runs in either direction and runs on AC may negate a unidirectional force as it applies to the basic rail gun circuit. We should remember the races are closed loops acting on multiple ball bearings thus the low resistance current path through the race to each ball bearing is fairly uniform. Logically the races cannot act like a one turn coil when the current/field should act equally in both directions simultaneously around the race to multiple evenly spaced points on the race to the ball bearings. As such all the forces should balance which may explain why it cannot self-start.


The best clue we have yet is that an "Alternating Current" producing a unidirectional force almost exclusively implies an inductive process producing a leading/lagging field phenomena. As well the fact that it will not self-start until a permanent magnetic or induced external magnetic field are present also suggests a leading/lagging field phenomena.

Like I said earlier, I believe the thing has to be set into motion to provide an offset in the fields.

The way I see it, when we apply current initially, the fields are probably balanced, no motion. But while current is flowing, when the thing is put into motion, the fields in the balls most likely bend the fields produced by the balls, and this offset probably gets greater with speed. So this would explain the how of working in either direction. Spin one way, and the offset is in place for that direction of spin, and likewise the other direction.


When we apply a biasing magnet to the system, the offset is already there. The fields created by currents in the system become altered and off balance without the push start.

Maybe this can be drawn up on FEMM to see what the fields look like, around the balls and the races.  I dont know if there is a FEMM prog that shows fields developed by electrical currents.


In my vid of the magnet rolling on the foil, if it were just a solid iron disk, it probably would not move, until we moved it while current is running through it. 

So it is possible that in the videos of a AA battery with a magnet and a wire simple motors, that the magnet could be replaced by an iron disk, then give it a spin in either direction.

This statement is very important,and the sole reason i have spent the time on this project. In this situation we need to apply an electrical current to create magnetic field's.
Now,think about this very carfully
For this motor to work,it dose NOT need an AC current. This motor will work just as well on a direct current<--Do you know what that means??. This means that the magnetic fields being created do not change. This also means that if we know what and where these magnetic fields are,we can replace the DC current that creates these magnetic fields with PM's.

Im hoping MH will stick with us on this one,as i believe that an all magnet motor could actually be designed from this bearing motor. There is no magnetic field created by DC current that cannot be created by PM's. I believe that MH him self said that the fields within a DC electromagnet are no different to that of a PM's field.

Why dose it take a DC current to create the magnetic field around the wire to get the simple 1 battery homopolar motor spining?. What is different to the field around the wire carrying the current than of the field around a PM?.

Tomorrow i will try placeing a PM on the outer bearing housing,and see what happens. Then i will place one on the shaft near the inner race,and see what happens.

Check out this guy.  He should enter into the next pulse motor build off!

Well I am going to run with AC's rail-gun-bearing-race analogy.

For starters, the bearing version is not as "clean" as the rail gun.  In the rail gun, each rail has current flow only up to the point of were the sliding cross-bar conductor is.  There is no current flow past the current position of the sliding cross-bar.   But in a circular bearing, the current can be sourced both from behind and ahead of the moving ball bearing, and that screws up the "required" magnetic field that you need to interact with the current flowing across the ball bearing.

Nevertheless, let's just put that problem aside and imagine that the two races of the ball bearing act like the rails in a rail gun.  In other words, they generate the required orthogonal magnetic field relative to the current flowing across the ball bearing.

I am ignoring the problems to get here:   You can model the force on the ball bearing as a single vector pushing tangentially on the dead center of the bearing.   If the ball bearing "sticks" to the inner race and "pushes on" the outer race then let's say that the outer ring of the ball bearing rotates clockwise while the axle remains fixed.  However, if the ball bearing "sticks" to the outer race and "pushes on" the inner race, then we can say that the axle will turn clockwise and the outer ring of the ball bearing remains fixed.  Note however, if the axle must remain fixed, then the outer ring of the ball bearing will turn counter-clockwise instead.

So, what this means is that if you assume that the bearings experience force because of the current flow, then the same force on the bearings can give you a motor that turns clockwise or counter-clockwise.  The spin direction will be determined by which way you start the motor with a push.  It depends if the bearings "stick" on the inner race and "push" on the outer race or vice-vera.

Hey Milehigh


Thank you for that link MH--https://www.youtube.com/watch?v=EEJtHyv2Rqo[/color][/font]


You know I could listen to inventors like Bill French talk all day because these guys have their feet planted firmly on the ground and yet their head way up in the clouds. It's these kinds of sincere people with so much knowledge and so many dreams that just make my day.


If there is one thing I think we can all agree on it is that at the end of the day it has to be real, it has to reasonable and understandable. We have more than enough wild ass theories out there but today we need things that work. I like your last post as well... stick and push, I never thought of that in this device however I had considered the concept in another context. Levitation was one and if an object is bouncing between two boundary conditions then one part of the time it isn't actually touching anything. It is levitating with very little friction just not all the time which kind put's a new spin on the concept of all or nothing.
