BEST vent hole pattern for Hub motors

[korpin]

I am having a phasor bike built by HPC and their new motors coming out are vented....they use a few bigger holes near the center to draw air in and more,smaller holes near the outside to draw air out....simple and effective and the holes are not as big as pictured here because they told me,the covers are a supporting structure

Run two wires down the hub motor phase wire hole/shaft and mount a small fan you zip tie to the stator with an on/off switch and it's own 12v battery pack Small) and turn it on when you stop the bike

Cooling fans inside Hub motors

Hi all, I've posted about this a few times in other threads, but I think it deserves a thread of it's own as I believe the idea has merit and I plan to try it in the future with my Crystalyte HS4065 once I repair it. If you take a look at Crystalyte Hx series motors (and many other motors)...

I reckon after eleven and a half years, the previous poster probably figured out some workable approach. Certainly this online community has developed different cooling strategies during that span of time.
