Hi,
I'm Jimit. I have an Emax Oneshot 125 ESC and a 920KV BLDC motor. I want to calculate the RPM of the motor. Can I calculate the RPM using the ESC? Also, what are the refresh rates of a normal ESC compared to an Oneshot ESC?
Thank you!

You should be able to determine the rpm from the pwm you send to the esc.
how to determine the rpm from the pwm I send to the esc?
Is this ESC connected to an Arduino?
Yes sir:)
If you are using the Servo library to control the ESC, then 0 = minimum RPM and 180 = maximum RPM.
So if the minimum is 0 RPM and the maximum is 10000 RPM then you can compute the RPM by:
RPM = float(val)*(10000.0/180.0) where val is the number (0 to 180) that you use in servo.write(val)
