Here it is. The continued development of the Dual Induction Split Spiral Motor.

Electro magnets added.
Steel magnet-holder added.
Please download the attached zip file containing PDF:s and DXF:s for examintion.

The rotor block holding the magnets securely in place will be ready in the next development phase.

Have you ever think, instead of using electromagnets, that are very close to the rotor magnets, and have induction problems, do something else. I'll give you my humble opinion. Instead of electromagnets, use moving magnets that are moved with a solenoid far away. The magnet will be pulled outwards, so there is less effect when the rotor magnet approaches the sticky spot. When the rotor magnet is at the sticky spot the solenoid will push the magnet inwards, so the rotor magnet will be repelled.

The moving magnet must continue the ramp when pulled away, so, when pulled, it must be further away than the last magnet in the ramp, and when pushed in, it must be closer than the first magnet of the next ramp.

I have done very simple experiments, but I have made a conclusion about the field strength. It decreases very much with distance, So little movement must be done with the moving magnets. I have tried pulling a metal bar from a magnet,and it takes some power. If a sheet of paper is placed between the magnet and the metal bar (paper thickness 0.1mm) the needed force is much lower. So I believe that the distance the moving magnet need to do, is not more than 2mm. Of course the magnetic ramp must have maximum distance difference from the rotor magnets 2mm. If you have problems with construction, with that level of accuracy, try to make the smallest difference you can.

The smaller the difference, the smaller the distance the moving magnets have to do.


That's my idea, hope it helps.

Sorry, No jpegs. But maybe you can get an Autocad trial version, or even more daringly, try getting it through a torrent....

No, I have not ever thought about using a mechanical sticky point solution. 
There is simply no gain in using a very fast moving object with lots of mass in the way you describe.

Just imagine the complexity of an mechanical solution pumping a magnet forwards and backwards in full speed at 6000Hz.
It is totaly impossible to make this type of design and keeping it simple. Every direction shift would consume heavy amounts of energy,
And it would be very very inefficient compared to a electro magnet of Supermalloy.

The solenoid your'e talking about have to be many times more efficient than the Supermalloy electro magnet
to make up for the loss of moving a heavy mass counter magnet at 6000Hz. It's impossible. 
And you would have to move the counter magnet more than a couple of millimeters. It's more like 2-3cm away to make any difference.

There's another thing to. You cannot change polarity using a moving counter magnet. End of story. Mechanical solution is dead.

I didn't realise that you designed the motor to turn so fast. You are right. Mechanical solution is impossible. By the way 6000Hz/2=3000hz if you have 2 segments or 6000/3=2000hz if you have 3 segments. Best case 2000hzX60=120000rpm. Can you build a motor that turns 120000rpm? It must be amazing.
