Question about torque calculation

in the liveplotter documentation i saw how to estimate/calculate the motor torque:

cancellation_token = start_liveplotter(lambda: [
(((my_odrive.axis0.encoder.pll_vel)/8192)60), # 8192 CPR encoder
((8.27
my_odrive.axis0.motor.current_control.Iq_setpoint/150) * 100), # Torque [N.cm] = (8.27 * Current [A] / KV) * 100
])

where does the 8.27 come from? What does this number represent?

Hi

Here is the simple version, if you need the more advanced version, send me a message

i am sorry but i am not Einstein. But if you want to send me the more advanced version, sure.

I just need to know what the 8.27 is. Is this number bound to a specific Motor, do i have to calculate it myself or this a constant of a specific property of something idk.

Hi

The calculation that Is send you is the explaination for the constant, 15√(3)/π ≈ 8.27

This is a constant that is the same for every motor (kinda)

okay thank you, now i got it:)
