I'm interested in some of the BLDC hub motors offered at http://www.uumotor.com/store. Each of their motors is offered in multiple versions listed by increasing voltage and increasing price. I sent them an enquiry asking what was different between two versions of a motor to give them different voltage ratings? I received a rather unsatisfactory reply from Tony Zhang <sales@uumotor.com> stating the difference between them was speed although from their listed speeds for each motor in kmh it appears they have identical KV. I pointed that out and asked what is different, why is the lower rated motor more likely to fail at higher voltages?
I'm awaiting his reply but wondering do they really make tweaks to each design to bump their ratings and prices every 12 volts or are they sleazy, selling identical motors with different ratings?
