Working Magnetic Motor on you tube??

[Bertoa]

Hallo DreamThinkBuild ... and Enjoy.

It's too simple to be true, this design of Mada Heng. It looks not difficult for replication. By turning the core magnet poles the rotor runs in opposite direction. I can't wait to explore this principle; you too? Always first the quest for the right parts. That delays this kind of projects unfortunately. Without some control this Mada Heng device is going to lock. Maybe it is not that difficult to disturb the balance (or sticky point) at the right moment.

Now you are talking! That's the correct principle ! Both the stator magnets and the rotor magnets must be running - equally and in opposite direction or one in rotary and one in displacement mode - the total momentu is zero while there is continuous movement. I saw that first in old patent...

This design will mot work. It is too good and simple to be true.
I have only made simulations of this, and the total torque in one cycle is zero.
The reason is because the rotary iron cores will rest between inner S and outer N. To escape this sticky spot you need torque that is not present at that point.
The rotor will turn clockwise as much as counter clockwise.

Hi Bertoa,

Another interesting design is to keep the magnets stationary but have a polarizing rotor. Finding the balance between repulsion and attraction is where this is going to lock.

Low-Q, I agree this set-up of the Mada Heng device will hang at the sticky spot. A static magnet device, like this and the whipmag, will fail. We need at least one variable magnet field, whether from the rotor or stator. This will preferably be feeded and controlled from outside the device. It doesn't matter if this variable field is generated by an electromagnet or a permanent magnet. Take CLaNZeRS whipmag replication; https://www.youtube.com/watch?v=cCVri4R31gU
None of these replications does control (power and syncronize) the small stator wheel from outside. The goal was that the whipmag has to run on it's own, just like this Mada Heng device. Maybe, with some outside help, more torque can be gained. We will see. The drawing of the next device has maybe a better chance to gain some OU.

Hi Bertoa,

I haven't built a replica but I've done some simple test with a linear version to see if it was possible to get the metal to move when polarized. What I found is that if you have the metal either to close to one magnet(N) or the other(S) it will just want to stick to it, in the middle it will just cancel and no movement.

I did build a test version of another patent that uses the surface tension of ferro fluid.

While this didn't work, it was a fun learning experience. The seals on the device broke when it slammed into a metal shelf so it looks like a mess. Attached picture of build.

If you look in this video at 6:58:

You will see that he puts a Lego block in ferro fluid and the surface tension pushes it to the side. I've been testing with this surface tension of the ferro fluid and you can get some rotation but the build up of liquid on the rotor will actually pull it back . Maybe a hydrophobic coating can overcome this(?). More testing is needed.
