Better heat dissipation, greater efficiency, greater bearing-reliability with directional stress on the shaft, etc.? I've never worked with nor have ever seen an outrunner motor(besides online at hobbycity.com) to know its issues with e-bike/e-scooter/e-what-have-you adaptation, so an abecedarian treatment might be appropriate.

Have you got a back of napkin sketch?

Hmm, would toilet paper work?
I doubt your idea is quite that shitty.
CNCAddict wrote:Yeah, this is all coming together pretty nicely. The motor I'm building will be "capable" of very high peak power levels somewhere north of 15Kw if it is geared correctly and run at high voltages. The problem is that the current controllers will not limit power when temps get out of hand. This is something I really worry about if Joe the plumber buys one of these. Riding hard in the mountains pulling 9Kw continuous would heat things up a lot...and ruin the motor. We need some sort of circuit to measure controller/motor temps and start beeping like mad and limit the throttle when temps get out of hand. This should be an easy project for anyone with a bit of programming skills

This raises a question. Will your motor or one of your motors (if you have multiple 60 series models) operate efficiently at 36v or 48v?
And a suggestion. I would do everything that you conveniently can do to encourage purchasers and make it easy for purchasers to assemble and install a system that is safe in the rain.
