A Flux-Based Expression of Induction Machine Magnetizing Inductance

Tending toward the adaptive modeling of main flux saturation in induction machine, this brief discloses the induction machine magnetizing inductance as an expression in terms of only

axis winding flux linkages. It will be shown that such an expression considerably facilitates the inclusion of main flux saturation effects in internal structure of the well-established winding flux linkage state-space model. The derivation procedure will be carried out without altering the structural equations of the generalized
