Running the AC24 at High RPM - maybe not

I'm still big-time sick today, but recovering quickly. In my efforts to understand the torque of the AC24 motor a bit more, I looked at the datasheet online at Azure Dynamics:

Hmm, it looks like the optimal operating point is really around 4500 RPM and torque drops off quite a bit at higher revs than that. In my frenzy to go on the freeway in first gear, I didn't really look at the operating characteristics of the motor. Also spinning the input shaft of the transmission above 4500 RPM continuously might wear it out sooner. Oh well, back to bed to recover...

I was about to point out the same thing. Peak torque is around 74 Nm at just under 5000 RPM. If you look at the AC55/DMOC445 page, you'll see peak power is right at the peak torque point as well, as you might expect. So, not being able to run over 5300 RPM might not be a huge disaster.
