If the magnet did not split and seperate, I'll have to agree with squee on it demagnetizing

... Can someone please explain to me why there are this hard spots on the pletti and why there aren´t any "hard spots" on a hacker or lehner?

Can someone _exactly_ explain the difference between the 2 and 4 pole engines? Or is there a website where it is explained in detail?

I only found this:

EDIT: I just saw the "Click here for written explanation" link on the page...

What about the burnt through coil?

If i turn the shaft i induce a flux within the coils - if one or more coils are burnt through there will be no flux and no hard spots ???

Is this totally nonsense?

If i pull the trigger the big maxx will turn slowly but you can easily hold the shaft with your fingers. Not enough power to turn.

Will shortly heating up the engine really demagnetize such strong magnets?
