Friedrich Luling Magnet Motor

[DreamThinkBuild]

Hi Stefan,

Thank you for posting that interesting video and English translation of the Luling magnet motor. There is a similar video here by British Pathe.

https://www.youtube.com/watch?v=G6cycmBwLb8

The following is only my interpretation so it could be wrong but may give an idea for someone.

He has two versions shown in the video a small desk top version which only has 2 rotor sections and the larger one which looks like 4 rotor sections with 4 spring arms attached, maybe what the 4x4 was referring to?

Going frame by frame it looks like there are two magnets on a arm which is driven by a cam. It is flush with the oncoming rotor but then is quickly snapped back by the spring and cam action. In between the two magnets looks to be a solid block of iron or electrical steel. When the magnets are in front the field extends outwards but when snapped back the field is neutralized through the block.

You can see this action in the video at 0:15 onwards that the rotor rapidly approaches the magnet then as the rotor gets near the magnets they are quickly snapped back.

After I did the drawings I realized that there could be an inverted operation where the metal is actually a single magnet and the iron/steel plates are what moves back and forth.

The only part that is still nagging me with this design is that there appears to be no friction when he spins it in the opposite direction but the magnets seems stationary. Maybe someone else has an idea for that?

Nice find Stefan.

From what I can see, the neutralization is accomplished by shunting magnetic field through a cut out, rotating iron bar.
There is an iron slab part that fits inside this cutout forming a magnetic flux path the moment a slab gets inserted into the cutout shaft by rotating the shaft.
Reminds me mechanical flux switching as in 'Ward Force' device of Steven Ward.

Its not a lot of power its called magnetic inertia ! THIS TYPE OF MOTOR HAS BEEN AROUND FOR 100 YEARS ! If they were any good they would have been mass produced by now. My one is different it can power a 22tone lorry but Stefan wont let me up load it here I wonder why ? R u reading this Stefan ?

@ATOM1
are you too stupid to upload a file or what ?

The Lüling motor has nothing to do with magnetic inertia,
but with neutralisation and shielding of the magnetic field of permanent magnets..

So looking forward to see your one...
