Hello; I don't understand why the KV rating of motors exists.
I have a background in electronics and have built and used both "Variable Direct Current Drives" and "Variable Frequency Drives" on machine tools.
The R/C motors are brushless 3 phase motors. Correct? I believe that the speed of the motor depends on the frequency of the supplied current and number of windings. Barring overloads, and residual losses the motor being fed by say 50 Hertz should turn at one speed, and if fed by 100 Hertz should go twice as fast. No KV rating needed. There is something lacking in my understanding of these motors.
Can someone enlighten me on where my knowledge is faulty???
I've seen several articles and videos where the KV rating was explained and demonstrated but I still don't grok it.
Thanks for any understanding you can impart!
