I am going through the AN1708 to understand FOC control and have a basic question. The motor model discussed in Equation 1 in the app note refers to a single im, R, L and bemf. For the 3-phase PMSM motor are these equations replicated 3x in the code to compute the values for each phase?
after looking at AN1708 it would appear it does NOT
as the other phases would be identical only shifted 120 deg
but it does have fault detection for all 3 winding's
I read AN 2520, along with other material, and now have a much better understanding. The estimator apparently calculates the estimated values of bemf in the alpha/beta domain and uses two equations using the Rm & Lm.
