Questions on heat

[Dafni]

Hi folks, I got another question to discuss here.
Where exactly is the heat in BL motors generated?? Is it the winings or the actual magnet that creates the heat?

I know our Neodymium magnets will loose the perma-magnetism above 120°C, but will gradually fade above 90 or 100°C.

Now, on my 9L I sometimes get readings up to 90°C on the can. Ususally it's hotter towards the rear end, where the wires stick out. I know this is already in the critical area, so I'm looking forward to Mikes heatsink.

Suggestions and thoughts are welcome!
Thanks alot
