I've been working with the factory that makes Q100 and 128 motors. I had them make (at my cost) Q100H prototypes with 0.35mm laminations, as well as 0.5mm Q128 cassette motors with 135mm spacing, all painted black inside and out for heat dissipation.
The 0.35mm lamination Q100H resulted in about 20% improvement in efficiency (and likely power handling) over it's 0.5mm counterpart to 84% peak. I am currently running the 330RPM 36V version with 12S using a stock S06S. Top speed no pedaling is about 28mph @ ~580W input because of the S06S current limit. WIth pedaling, top speed is about 34mph. I can also cruise over 30mph all day long without any issues of overheating. I only weigh 150lbs and am a strong biker so take that into consideration.
I haven't tried the 0.5mm Q128H yet, but I'm only expecting modest gains on flat ground over the 0.35mm Q100H based on the dyno information. Looks like significantly more torque however.
I plan on having them make 0.35mm Q128H motors in the future but I could not meet their MOQ this round. I would expect roughly 40% more output over the 0.35mm Q100H based on mass (3kg vs 2.2kg).
I'm in the process of building a dyno, but for now I have attached the test data they gave me.
Pricing for these motors would likely be around $175 for the 100H and $225 for the 128 cassette, shipping from USA. Do you guys have any interest in these motors? What RPM @ 36V and hole configuration (eg 32 or 36H) would you like to see?
