I thought electric motors in general had a mostly flat torque curve, right from the go and up until a certain rpm when it drops (unlike combustion engines). The power of course changes and that affects efficiency in general, but power is a result of torque X rpm so if you accelerate it draws more current, so economy is about rpm not torque. Or so I believed.
In my experience, power torque curves are parabolic but all 3 parameters must be on the same plot. The current plot is fairly linear as you can see from the example plot that I posted. If you accelerate (climb), there is more torque required and your plot points shift to the right. This means more motor torque required and definitely more current. The motor efficiency will also shift to the right and decline.
We need the 2312 motor torque curves.
