Flynn PP Motor Idea

[Drak]

longwolf,

Check here if you'd like an idea of how a U shaped device would look.
http://peswiki.com/index.php/Directory:Flynn_Parallel_Path_OEM_motor

The last 2 images on the page only show one arm of each FPP.
The second arm would be placed above the disk made for holding the attractive metal pieces.

  I seen that earlier today, I'm trying to figure out where the magnents go. Isn't the whole purpose of the FPP is to stear magnents? Looks like he has a pretty interesting design.

It seems that cutting the laminates wrecked the annealing.

  It did? I wonder how, because laminates would need to be cut on this motor too. Hmmm....

With the short U's that Mike used, the magnets would go on the 'corners' of the U's one each side of the coil.
Then the second stack of laminates is placed on top of those magnets, sandwiching the rotor.

I believe you could use the ready made U's without cutting them.
Just find some that are close enough to the right size already.

The ready-made laminates have mounting wholes in those corners
But longer arms would allow you to move the magnets closer to the ends of the arms and off of the mounting holes.

Here are links to a few sites that sell laminates:

I don't think Mike was happy with the results of that motor.

I think the peswiki group is working on another design that they expect to work better.

(bottom line - I wouldn't copy the design without talking to Mike about it.  I think he would steer you away from it.)

Mike seems to have stopped trying to make this motor.
It seems that cutting the laminates wrecked the annealing.

I think waterjet cutting would be a good way to cut lams if you have access to it.  You need to back up the steel with something like plastic because it is so thin the waterjet will try to curl the edges.  You can of course stack numerous layers on a waterjet if you can hold them together.

Laser cutting supposedly works well too, but I would worry more about the heat of laser cutting affecting the lams.  I don't think it has the curling problem.

Hello jake,

Cutting laminents will only effect the annealing of the lam very close to the cut.  In most casses this will not hurt them.
