Hi

I have used the  InstaSPIN Motor FOC  matched some PMSM motors well, but can not matche some BLDC motors。 I wonder if the back EMF waveform of the motor is square, InstaSPIN Motor FOC can still control it ok? For example, the back EMF is shown in the figure below. Can InstaSPIN Motor FOC control it well?
