Phase Current Matrix

The Phase Current Matrix has Z elements and describes the current distribution (p.u.) within the slots just for one phase. Each element of it is also equal to the per unit filling degree of the corresponding slot.
The sign (±) is assigned according to “go-side” or “return-side” of the coils.
