Abstract

Most electrical machine design optimization processes do not include constraints imposedduring manufacture. Ignoring cutting tolerance when optimizing a machine, for example, can result in amachine who’s performance is susceptible to manufacturing defects. Ideally, design of electrical machinesfor high-volume production should account for the impact of manufacturing tolerance, material variation andmaterial processing. This ‘robust’ design ensures that models realistically predict achievable performance,thereby mitigating the risk of obsolescence during mass production. This paper introduces a procedureto address the influence of lamination punching in the robust design of electrical machines. A six-phasesegmented switch reluctance motor is simulated with a multi-layer finite element model to account forthe effects of punching on the magnetic characteristics of the electrical steel laminations. Additionally,to enhance the accuracy of finite element model, a geometry-dependent excitation and control circuit isintegrated with the finite element model. The results demonstrate that the optimization model presentedincreases the likely torque output of a machine built with a normal distribution of manufacturing errors.
