### Abstract

Multiphase phase induction machines are usually modeled using multiple dq planes, where complete decoupling between these sequence planes is usually assumed. This assumption may be accepted if the magnetic circuit is assumed linear. However, at rated operating conditions, a degree of magnetic saturation is normally expected in induction machines, which breaks this generic complete decoupling assumption. Considering the saturation effects in multiphase induction machine, mathematical modeling has not been widely addressed in the literature. This paper introduces a five-phase induction machine model based on the well-known conventional dq model with multiple planes considering the effect of magnetic saturation. The flux correction method is used to represent the effect of magnetic saturation with modifications to include the effect of cross coupling between fundamental and third sequence planes due to the saturation effect. Experimental validation is carried out using a 1.5Hp prototype five-phase induction machine.
