Thanks, I take back what I said, I'm not getting less confused at all

I've seen that the load on the motor is a big one. With the same motor, the load from a very light car geared to do 10mph will be much lower than a heavy car geared to do 100mph.

I've also seen those engine dyno curves, using a flywheel test machine. Does that mean if you change the flywheel weight, you drastically change the torque and power curves you're going to see from the same motor?

But if the motor decides how much current it wants in a situation, how do things like turbo and boost work? If the ESC can't simply put more current into the motor, how is the motor understanding it needs to work harder?
