Thanks John.
I have to admit that your explanation is allready above my league.
These are similar wheels for sale:

https://www.alibaba.com/product-detail/MP-3000W-hub-motor-with-24_60475092395.html
Its slightly bigger than what will fit in a freehub. The specs are there but all I can make from it that with 88% efficiency it will not generate that much heat with 100w.
