But surely there’s some very good clues you can look toward such as the motor size constant (km) giving the torque to electrical resistance which can be used to compare all motors, and the no-load current draw at highest speed.
I believe the iron losses will be revealed accurately through the no-load draw until the motor were saturated, but other than that the current drawn with no load at a certain erpm will be pretty much the same in use
I have an Exway Flex board.
I’m making a new 12S4p P42 battery and Ubox V2. Wheels 6 inch Flipsky 150x50 Pneumatic with 60T.Now the question I want good efficient small motors 6365-6368. Question what do you think about Maytech 6365 170KV 3500W. The motor has temperature sensors and half sensors on all 3 phases.

Ill have a set of these coming in soon-ish if you want to see the motor detection results vs some flipsky 6384’s
Yes pleace 
Wath have you order ? Battery 12s ?
Hm? I have a set of the reacher 7490’s coming in fron SKP’s recent motor purchase. Will be running them on a 13S4P with a spintend ubox.
Kv from 7490 ? 175kv ?
Gearbox or 5/1 ?
175kv, belt drives, currently running 15/72 but will be switching to 15/78 with 20mm wide belts soon.
have one step `? test ?
Reacher 7490 265Kv
