PERENDEV PDF

They isolate the magnetic field around the magnets. This way of isolating magnets is very known: look at pot magnets! The steel is a better guider of magnetism than the air and that is why the magnetic flux chooses to travel through the steel and you are cutting the field short! Steel gets magnetized attracted , it is a way of isolating that is frequently used with pot magnets.

If the Perendev motor works, then it has to be with that kind of isolation; otherwise the repelling power is equal to the attracting power on the sides of the magnets!

Trying to understand the Perendev motor Calculation number of magnets: by Tero Ranta On top of the middle white disk there is a metallic flange that has 6 holes 60 degrees apart there is a threaded rod in one of the holes. Now you can draw lines that go through the 6 holes black lines. Then project the black lines downwards the same heighth yellow as the metallic flange and in the same direction as the shaft red line.

The projected lines are blue and the angle between them is 60 degrees. Thus you have 30 magnets on the disks. Click here to see a video of the device at www. I have been studying the Perendev motor lately to see just how they have the offsets set up on the main wheel. I was also looking at some diagrams Dan made of the offsets and I finally figured out exactly how they did it.

I took a clip from the flash video and the video of the working model and I could see just how the offsets were made by doing a cheap line test. What I did next was make a simple animation that I could study to see just how they accomplished the off balanced effect in the motor: I attached the animation to this e-mail so you can look at it but I can see clearly here how the balancing effect is happening.

From this idea, I figured out a way to modify my original tri-phase designs so that these three-phase offsets can be applied. I simply segmented the stator magnets up into three sections to represent the offsets of the three wheels on the Perendev and I got this final layout: Click here if you want to see a replication of this simulation, together with a torque calculation and results. This here is also an animation that I attached to the e-mail for you to look at.

It basically has the same three offsets as the Perendev motor and beautifully accomplishes the unbalanced effect. I know that this diagram looks like an earlier model that I made but this one appears to actually work just from looking at the simulation animation.

It appears that the motor will cog when the lines of flux are at a maximum density. Besides tracing out the magnetic lines have you done any calculations on the forces?

You can do this by differentiating the energy in the magnetic cicuit. How do you calculate the amount of force acting on each magnet exactly? Knowing this would take much of the guesswork out of my designs. I really have no idea if it will work until I can bench test it.

What do you think about the whole design concept in general? The main idea is to always have two magnets helping to push one magnet past the sticky spot. But the angles, spacing, size of the wheel, and number of magnets are the variables I have to work with. However, it would be invaluable if I could find a way to simulate the forces that all the magnets exert on each other. Using magnets 1.

Extending the offset distance to. I told you at that time I anticipated getting some good software and I would do some 3D work for you when I got it. But I now have a copy of SolidWorks and it is all I had hoped for and more!

If you are interested in sharing your insights I would love to know where you are going with the Phi relationship. As I think about it, this would be very close to the region where you would get maximum attraction or repulsion in a plane 90 degrees to the magnet faces, and you may be onto something quite important here.
