This paper presents the design process of a sensorless-oriented interior permanent magnet synchronous motor (IPMSM) with concentrated winding, based on spatial saliency for traction in electric vehicles. The purpose of the design method is to ultimately achieve both stable rotor position detection and acceptable mechanical performances, under the maximum load conditions. After
describing the evaluating procedure of sensorless control viability, the geometry design parameters are analyzed to figure out which ones have a positive effect on sensorless drive. Focusing on the parameter analysis, a prototype and improved model are proposed. Optimization is conducted, using response surface methodology (RSM) with the factors selected by design of experiment (DOE).
Finally, the validity of the design results is verified by comparison with the simulations and the tests. It is founded that the accuracy of the rotor position estimation and mechanical characteristics can be improved simultaneously by means of the proper geometry design.
