Abstract

To achieve efficient multi-port model order reduction, a multi-port Cauer ladder network (CLN) method is formulated that directly yields resistance and inductance matrices that constitute the network elements in the matrix Cauer form. The eddy-current field driven by multiple power sources is accurately reconstructed using a small number of network elements. The matrix Cauer form achieves faster convergence of the transfer function than a single-port CLN method and almost the same convergence as a block Padé via Lanczos (PVL) method.

Abstract

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.

Abstract

The Cauer ladder network (CLN) method provides an efficient representation of eddy-current fields. This paper proposes a reformulation of the CLN method that considers expansion points using the magnetic/current vector potential. To cover a wide range of frequencies, the expansion point may be changed at a later stage of the network. Only a few stages of the ladder network are required for the eddy-current field to be reconstructed accurately around the target frequency using the expansion points.
