I have a (probably basic) question about BLDC motors:
Motor speed is supposedly given by kV * battery voltage. But the ESC determines the motor RPM through pulsing current to the different windings, right?
Is kV*voltage just the max rpm the motor can run at? Or is a motor with too high kV very inefficient at RPM:s much lower than kV*voltage?
I'm confused, grateful for any kind of clarification!
