Estimation of Equivalent Circuit Parameters of Multiphase Induction Machines by Exploitation of Space Harmonic Relations

A multiphase induction machine model using vector space decomposition or harmonic plane decomposition provides insights into many space harmonics through decoupled reference frames, each hosting specific space vectors related to particular harmonics. The dynamics of each voltage and current space vector are described by an equivalent circuit, whose parameters must be obtained either by finite-element analysis or laboratory measurements. This paper presents and experimentally verifies a methodology for calculating these parameters from a single configuration, with minimal knowledge of the geometrical dimensions of the machine.Part of ISBN 979-8-3503-9899-1QC 20230925
