Going by what you said, the motor has the potential to put out 10kW.
Just wondering how you came to that conclusion....was it though physical testing or through calculation?
The controller could do 10kw for a time, but I'm not so sure about the motor. From user reports, the X5 motors appear to handle up to 5kw depending on air temperature Cooling holes would help and with enough air, you can about double the continuous rating of most motors. I would put the continuous output rating closer to 2.5kw in general.
You might get it to pull 10kw on acceleration, but I doubt you could get the motor to pull that much at any kind of speed, since the back EMF will limit how much current the motor will take. If you used a 5302 on a large wheel, you might get it to draw more, but the efficiency would suffer and the thing would be likely to self-destruct.
With brushless motors, it's next to impossible to run two motors off one controller, so the limiting factor will be motor heating if you have enough batteries.
There are BIGGER motors out there. The Mars motor (brushless Etek) is one example. Some of the newer full size scooters have bigger motors.
