Abstract: The identification of the magnetic material characteristics for the
switched reluctance motor by solving an inverse problem is presented. The
inverse problem aims at identifying the magnetic material parameter values of
the magnetic circuit, starting from measured torque profiles. The computational
time of the inverse problem is appreciably reduced by implementing a space
mapping-based inverse approach. Using the space mapping technique, we combine
the computationally intensive finite element model with a much faster magnetic
network model. The proposed approach is very helpful for the material
identification problem on the electrical machine, and the obtained results
reveal the success and the reliability of the proposed scheme.
