KV / Gearing choices

[aqwut]

man...this is gettin' technical... there are way too many factors...... but I do agree W = V * A * Effieciency.... but every motor has their own sweet spots.... Lehner has a whole bunch of excel files with motor data on different voltages/amps etc........ some motors runs 94% effiency @ 24000 rpms and some at 70000 rpms..... but lower KV ratings motor has a more broad effiency range at lower amps etc.... for example some hi-amps motors have a good effieciency range at hi-amps...

That's the stuff boys, keep it coming!

Actually I wanted to hear experiences and theories about setups ON THE SAME VOLTAGE, but it's all good. I appreciate each and any post here.

I feel the same questions are bothering many of us. Nice to have a collection of opinions.

Thank you, fellas
