This is why I want one thats marginally more efficient though. The speed and torque is about right for me, but the buffer would let me feel like I could abuse it as much as I want without worrying about burn out.
That's my thinking. ~20% more efficiency means ~20% less heat, meaning you can run this motor that much harder.
I have run every version of the Q100 328(3 different reduction ratios by the way)over the last 3 years and my experience is, motor over-heating has not been an issue.
What happens, in my case at least, is this.
As the power curve aproaches max., The motor becomes current limited, as opposed to RPM limited of a slower speed motor.
The little 6-FET controllers try and run at max. all the time and they become very hot(I have melted the kit's crimp-on bullets on the phase wires).
Going to a larger controller is a work-a-around that really doesn't address the motor's appetite.
I have run up to 15S and there is little increase in top speed without a corrasponding increase in Amps.
The problem then becomes the motor at 12S plus/20-22 Amps makes the motor at start, rough off the line with some hammering.
I guess I should add here that I am not a light and fit rider(working on it) and my bike is not a road bike(more like an adventure bike).
Frankly, I am continiously amazed at the speeds you guys can reach on a single 328, 35 mph! My bike wouldn't do that if I threw it off a cliff
But the funny thing is, my real world experiences match perfectly the results of the Ebike CA. I guess Justin modeled the sim. with a over-weight senior.
Running 2WD(standard 328's)on 12S with 15 Amp controllers would get me to 28 mph. As fast as I would want to go, but the mid-range was doggy.
The advantage of the customized motors, based on the power curve charts, as I see it is this.
There is an increase thru the curve AND an extension on the top end as well.
So a 260H, I would assume, would have the same, or stronger, "git" off the line, while at the same time, the rpm limit will be extended. The best of both Worlds.
For me personaly, i ride at bicycle speeds(nomal rider, not the Olympic type like you guys),and the 328C on 17 A is plenty for that, but since it's 2WD, I have the Q100H on the frt. when I need to really scoot.
But what I am still interested in is a CST with the 260 gears. Pretty sure both the lastest H's and C's use the same 8T sun gears, it should be doable(and visa-versa) by just swapping gears. Just a matter of buying two motors to make one.
