How does O-drive determine q-axis current without knowing the motor’s winding
type (wye vs delta)? For example, does it assume all motors are wye wound?
I’m aware that there’s a transformation from line current (what can be measured by the drive) to q-axis current, but
that relationship depends on the winding type, so I was wondering how this transformation is possible without knowing the winding type. It seems possible, since all line current goes to q-axis current with proper, in-phase commutation (i.e. d-axis current is zero). Can anyone help me understand this?
