Cant figure this out,
without getting into motor efficiency, load, torque. (Simply) I know if you lower a motor's voltage with no load the rpm's go down as well as the amps drawn but what about the watts.
36v motor draws 16.6a and 600w
Lower the voltage to
24v motor draws 11a but converting to watts 24 x 11 = 264 but wattage should be around 400w.
I can't find any conversion equations for this situation.
