A new motor I spotted, let me know what you lot think.

Here are the specs listed at the link below I suspect they are a little over the top in terms of continuous power ratings in hot weather but the specs look good for minimal reduction need. I may get one to test out, I have an enquiry pending to see if I can get more specs like
magnet type?
dynamic balance ?
stator laminate thickness ?
magnet retainers ?
back iron thickness ?
air gap ?
poles /slots?
