Design Optimization of Switched Reluctance Machines for Maximum Torque/Current Using BEM-Based Sensitivity Analysis
نویسنده
چکیده
One challenge to predict output performance characteristics of switched reluctance machines (SRM) is the accurate estimation of the minimum inductance of the stator phase at unaligned position of the rotor. In this paper, boundary element method (BEM) is used for this purpose while avoiding time-consuming numerical integrations. So, the method is investigated in terms of accuracy and computational time. Then, to design a SRM with maximum torque per current ratio, a fast optimization method based on sensitivity analysis is presented where BEM is used to evaluate the minimum inductance of the stator phase and a magnetic equivalent circuit is used to estimate the maximum inductance at aligned position of the rotor.
