If rotor is not a magnet, i would love to hear a SENSIBLE theory of exactly what is happening. How is it prevented from sticking.

Proceeding with the assumption rotor is a magnet..

If we look at https://youtu.be/WT_UIpbFKc0?t=31 as rotor spins toward the camera, opposite to working direction, and the part that goes back n forth in work direction is stationary, it moves smoothly, apparently without slightest cogging. Obviously, whatever forces present are balanced.

One possible explanation is that rotor is attracted to the stationary plate with square hole, let's call it the U plate, and the oscillating block, let's just call it the block, behind is a repelling magnet, perfectly neutralizing the attraction.

In work direction, the  block is moved back and rotor is attracted to the U plate and when it's just about to stick the block is released, neutralizing the attraction and rotor moves forward without cogging.

The issue with this is that the block would stick to U bar and system would not be efficient.

However this can be easily solved by widening the hole in the U bar and shortening the block, so rotor is attracted to the U bar on the sides, far from the center, and is repelled by the block in the center, so when block moves away after neutralizing the attraction it hardly sees the U bar at all.

Also important note that U plate is covering another metal block, maybe solid or hollow, may be ferromagnetic or not. Many maybes. That is why in my opinion is better to take from it what makes most sense to you are the principles used, but not copy it literally.

Thank you for your quick feedback.

May I ask what makes you assume the rotor is a Magnet? Or has a Magnet?
Did you see something that hints to it? Maybe you can point me to some frames?

In Frame 1892 I named some parts to identify them.
What is the Magnet or rather the Magnet-System?

I did some testings regarding the Magnet system. And it seems that the two outer Blocks are Magnets.
The middle one could be iron. If the two arcs are covering top and bottom of these Blocks, the armature can pass.
If one is open or rather swung away, it attracts the armature.

This is also backed up with Frame 2537. Where you can see that an Arc without Arm is put on Top of the Blocks to have this
side's Magnet System neutral at all times. The actually Arc that is usually in charge of doing so, is parked away, which can be seen as
well, in the same Frame, and Frame 0655.
Without the arm was necessary, so that the Camera can look through but keep the Motor able to operate.

Ufo had the thought, that with these two arcs per Magnet System, one could change the direction of the rotation.
Which sounds reasonable to me.

@Ufo,
I am thinking of this for quite some time...
Compared to an ICE, like in a car, If I shift the first gear, and the rpm goes down, I put the pedal down, and the rpm goes up.
If I maintain this, it will keep my speed and rpm up. This is more or less done by changing the amount of Gas and Oxygen that ignites.
How do you maintain the speed, or rather the rpm? How do you change the amount of Gas and Oxygen? And what is your Gas and Oxygen?

Hello Semi,


The Air Pressure regulation is your "accelerator" (in my model, my concept though)
When Air pressure lowers, the Piston does not fully strokes outwards, hence, the air gap is not spread to a maximum, so, speed decreases.


And so, in just a mechanical setup (no pneumatics), it bolts down to the Air Gap of your Neutralization switching side, whether it is Attract or Repulse side.


Of course, in more advanced models, we could also adjust the Stationary side Air Gap, and by widening it (in either sides) the speed will come down.

What happens with your motion if you leave the outer repulsion side out? I've noticed on a test rig, the way how you pull the attraction side away,
will give the rotor a different push.

Regards
Semi

In my setup, the Repulse side is the Force side to propulse Rotor...if I take off Stator side Repulse magnet, Neutralization is gone...and so the attract side, with two Neo's 52 grade at close gap, will stick so much, that I do not think, even the 65 Newton Force of air piston, would separate them.

This is all about Geometry, Semi...all magnets or electromagnets have an Imaginary Bisector line that crosses between both poles, perpendicular to Bloch Wall, right at the center of magnet embodiment, and so this line will serve as your "timing" line, as it also dictates the Rotation sense.


This Bisector Line is also applicable for PM or Universal DC electric motors timing setup.


If this line between magnets in the Rotor versus Stator is fully aligned into a straight line...when you separate attraction, it could fire in either direction, randomly...so, to prevent this, Rotor Bisector Line must be aligned passing the Stator line towards the direction of rotation desired...just one to two degrees will do it.


And so, also adding to your previous question of how to accelerate or keep steady this motor, this Angular settings between Rotor Bisector line versus Stator Bisector Line will also contribute to Motor Force...or the wider this Angle, the slower and less force motor will have...the closest the two angles, like 1 or 2 degrees...will add a Higher Torque that will develop in higher speeds.


However, varying this angle, while motor is running, will require some clever mechanical build on the Stator Magnets Base.


Air Pressure regulation being much easier to apply while running, and conveying the same results.




Hope this answers your questions.




Regards Friend

You are using different terminology so it's hard to understand what exactly you mean by arcs, by outer blocks (i assume you mean middle plate to the left and right from the central hole but maybe you dont)... It's next to impossible to understand each other like this. We must use exactly the same terminology. Can we for sake of simplicity keep calling the middle plate U plate and oscillating block just the block.

Now, if rotor is not a magnet how come it passes so effortlessly by the stationary U plate and the block, without any cogging.

Clearly, if rotor is steel and either U plate or the block are magnetic, rotor would stick, but it does not...

You seem to suggest flux is diverted and you presumably mean this is done in work direction. How exactly did you imagine this, as i said before whatever you use to divert the flux becomes a new sticky point (more on that below).

But before all i'd like you to explain why rotor does not stick in first 3 rotations linked above.

Now, this is definitely not how Luling did it but it's worth mentioning and i already mentioned this on another thread. How to shield the magnetic field without sticking. By using block which is made of finely adjusted array of same pole magnets forced together on iron plate of proper thickness.

Say you want to shield attraction without sticking since you suggest rotor is not a magnet...

This has to be made so precisely so that when this shield is put in exact middle between the stator magnet and rotor steel, the repulsion of the magnets of the shield facing the stator magnet is perfectly neutralized by the thickness of the iron in front or behind these magnets, so shield can be inserted or removed effortlessly.

Basically imagine few hundred small neodymium blocks all forced together in an iron sleeve of proper thickness, adjusted so that at certain distance it can totally shutter the stator magnet with minimum investment of energy.

This is one clever design that is delicate to make but would solve the issue. However there is no evidence Luling used this type of shield.

Something along the similar lines but not too close

Yes this is soo true. That is why I named the parts in my Frame pics.

To be honest, I can't even follow you what you mean by U-Plate.

Now, if rotor is not a magnet how come it passes so effortlessly by the stationary U plate and the block, without any cogging.
Clearly, if rotor is steel and either U plate or the block are magnetic, rotor would stick, but it does not...

What makes you think this? In fact, on my testings the Iron bar dropped as soon as I put the upper bar on top.
It was still attached, but it was totally separated with a very light touch. So I would guess, it is a bit like Ufos rig.
In every resolution the Magnets will stick or rather cog, but the momentum will be enough to push it further through.
And in "real time" you won't notice it, as soon as it starts spinning.

The Air Pressure regulation is your "accelerator" (in my model, my concept though)
When Air pressure lowers, the Piston does not fully strokes outwards, hence, the air gap is not spread to a maximum, so, speed decreases.
And so, in just a mechanical setup (no pneumatics), it bolts down to the Air Gap of your Neutralization switching side, whether it is Attract or Repulse side.

I have noticed the speed on how fast you are pulling it away, matters as well.
So this actually means, that an Air Flow Regulation to the stroking piston would be the Gas Pedal. Mechanical factors like Air Gap etc. are fixed.

This is all about Geometry, Semi...all magnets or electromagnets have an Imaginary Bisector line that crosses between both poles, perpendicular to Bloch Wall, right at the center of magnet embodiment, and so this line will serve as your "timing" line, as it also dictates the Rotation sense.

Ok so even by leaving the repulsion side out, the back stroke will cause a rotation, but its direction is undefined. Got it.
