This is why my magnet motor projects doesn't work

[Low-Q]

Hello Dough1,
I know all that😊


My point wasn't to display a working magnetmotor, but to display why magnets can't do work. The drawing was just an example of an idea how to make them do work, but I fully understand that it will never work.
Permanentmagnets are conservative. They don't provide energy to the surrounding, just a passive magnetic field.


I am soon finising a project like the drawing above. This project will cast light on what people doesn't seam to grasp. Namely why permanentmagnet motors can't work.


In this thread, I have no intension to claim that these motors will work, but post a proof about why they CAN'T work ;-). So people don't need to wonder if it is worth building big expenseve projects that will never work.


Just as an attempt to help people here to not waste time on permanentmagnet motors.

Your thinking the magnetic field is going to work the same way a water wheel works when water flows by gravity over the wheel to push the paddles or buckets. The magnetic field doesnt flow like that. what is termed polarization is just a term used by people. What passes for North and south is just in relation to the earths fields so a compass can be used for navigation and people can communicate a location or direction to one another. It could just as easily have been flip flopped. The graphic images used to define a magnetic field are only relevant words of description for a particular conversation. They only really seem3 to expand and contact no wind like effect in the terms your thinking by your drawing. There is just as much pull back after the disc passes the apex of the field south to north north to south and each against it's own sign. Your going to end up chasing the mono pole which would make the magnet not a magnet. If you try to chase the neutral field of non polarized material that is still a pole just that is a neutral pole attracted to any pole different from itself. A permanent magnets field is established, it can only be distorted or destroyed. To squeeze one magnet past another under repulsion of fields has the same push back before and after and then will certainly get stuck in attraction as it is pulled back once it passes the apex of the field it is attracted to.

Oops!!! That was a large picture. I sent the picture from my phone.
Couldn't make it smaller on the phone...

A better "picture" from SketchUp

I will hotglue a long carbon rod on the top of the upper knob over the rotormagnet. The knob is connected to the rotormagnet through a ballbearing. The rod will be attached to a piece that can glide in a track. The complete system will remind you of a steam engine - except there is no steam heat or water.
The long rod will keep the orientation of the rotormagnet stable within a few degrees.


The system is already tested as I let the stator spin and the rotor fixed. If I by hand keep the magnet orientated with the rotation of the stator (black ring where one half is opposite polarisation of the other half), there is positive torque at all places in the complete cycle. I did not expect this, but it makes sense now.


This experiment is done with the hand involved, where the stator is spinning instead of the rotor. Therefor I orintated the magnet by hand to keep it polarized in the same direction relative to the turning stator. So from the stators point of view, the rotormagnet is fixed in one direction throughout the cycle as it makes its cycle.
The interesting part is how our brain falsly think that this experiment will work if we let the carbon rod do the same job as my hand - keepeng the magnet orientated the same direction in space while the stator is fixed and the rotor is spinning as it is finally supposed to.


It should appear to be the same deal, right? But it's not - I think. Even if the relationship between the rotor and stator is apparently the very same.


I will continue this on monday. Now I am visiting my parents in law with my wife and kids untill sunday evening, Norwegian time.


I'll post a video of both experiments on monday or tuesday.


Untill then, have a nice weekend 😊


Vidar.

I couldn't keep away from pen and paper. I just figured out a simpler way to keep the stator magnets in same direction.
I will also remind you that this experiment is not suppose to work. Its just for demonstration - and some fun.


Drawn 4 rotormagnets to show the concept of fixed polarization.
Guide rotor X is keeping the rotormagnets in correct direction.
The rotor magnets is attached to the main rotor Y.
A and B is the direction the rotormagnets wants to go. The torque from these balance out.
1 and 2 is the direction the rotor assumingly will go.


The large ring is the statormagnet. South pointing towards center on the left side. Opposite on the right side.
