Thanks!If you want good acceleration torque even as you approach max speed, you'll have to gear it for a higher speed by some amount. I'm not sure exactly how much, but you can use the ebikes.ca motor simulator to get the approximate idea--the torque curve it has will intersect the speed curve at the point you don't get any faster. Change parameters (voltage, current, and/or gear ratio for a middrive) until the torque is still as high as you want it to be while at the maximum speed you want to go.
I'm still not 100% sure if I have the custom motor settings correct, will be digging into J Bjork's posts to compare what they'd used.
Is it the case that motor torque starts decreasing once the supplied voltage reaches half the battery voltage, or did I dream that? if it is true, what's the best terminology to start searching and understanding that with?
