Model Order Reduction of an Induction Motor Using a Cauer Ladder Network

In this article, a method for motor model order reduction is developed using the Cauer ladder network (CLN). The analyzed domain is decomposed into stator and mover domains, where the multiport CLN of each domain is constructed independently of the other. The two domains are connected through electromagnetic field modes at the boundary. The boundary condition is derived from the coordinate transformation. The reduced model accurately reconstructs the induction motor property affected by slot harmonics.
