Edit: Thinking more on it. JesseK is "correct" as far as I can tell. Because of the pulsing of the output you are limiting the amount of current which limits the amount of torque. He is correct but I wanted to make sure there was no confusion about how an ESC worked. |
Hmm
The second paragraph under "Theory of a Speed Controller" states that it's an 'averaged' effect of lowering the voltage by switching the full-voltage signal on and off. Later on the page, a figure shows the effect of the PWM switching on current as if the signal 'pulses' the current, thereby averaging it to a lower value as well. Rather than neither I'm inclined so say 'both' ... but really I'm just getting confused.
I'll look at it more later. Thanks for the link.
