Design Space Analysis Including Experimental Verification for an Electrical Machine Based on a Parametric and Functional IPMSM Model

Abstract

In this article, based on the recommendations of systems engineering, a procedure for generating a parametric and functional interior permanent magnet synchronous motor model is proposed. The developed and applied current-adaptive procedure allows to transform the functional relationships of the motor topologies into an advanced model with higher prediction accuracy over a considerably extended definition range. Compared to the state of the art, the proposed approach allows a more general and flexible analysis of electrical machines. A study demonstrates through multicriteria optimization that the design space has a major influence on efficiency and must be taken into account when defining architectures. Existing approaches are typically limited by model constraints to local investigations, the proposed method has advantages over these procedures. In addition to the analysis and optimization of systems, it is shown that the proposed procedure supports decision-making processes due to the integrated system focus. Potentials are identified and discussed in terms of efficiency-enhancing opportunities. A prototype was built and measured to verify the results.
