I guess I have to ask, what kind of an efficiency chart?
Something like this? Or do you want a full torque/eff curves?
This is from the current production 1515, at 15.4V: Vertical is efficiency, horizontal is torque output in newton meters.
At 200W out, eff is about 80%. At 400W out, eff hits 90% and stays above 90% to over 1000W.
However, be aware continuous output power is not this high -- the motors cannot shed 100W of waste heat for long. :)
These motors are designed for low continuous power, and high efficiency at high (intermittent) output power.
Also, please note that this is running through a gear (our dyno cannot run at 35000RPM) -- so the efficiency is actually a few percent higher.
