[BUG] Fix KV initialization

[runger1101001]

like this

can someone check my math make sure im not crazy lol

Change the sqrt(2) to sqrt(3) and it should be ok.
But maybe put the sqrt(3) somewhere else. It doesn't make sense to have a strange kv with the same name.

Because the id iq vd and vq are like phase-zero quantities. The kv is in phase-phase.

I think you should change it here

Arduino-FOC/src/BLDCMotor.cpp

Line 399 in f9e9a2d

if (_isset(KV_rating)) voltage_bemf = shaft_velocity/KV_rating/_RPM_TO_RADS;

Is the code ment for motors with a trapezoidal back emf? Because if I recall correctly than it could be wrong what I just said. I only work with sinusoidal bemf motors.
