An optimal design technique for high speed single-sided linear induction motors using mathematical programming method

The authors propose a novel design technique that is based on a combination of the linear programming method for solving the corresponding optimization problem and the finite-element method for analyzing the electromagnetic field numerically. When this technique is applied to the design of a linear induction motor (LIM), the exciting currents of the primary windings are optimized so that the LIM generates the maximum force at arbitrary power frequency and stator velocity. Application of the technique to the HSST-03 system gives satisfying results. It is found that although the distribution of the optimal exciting current varies considerably depending on the vehicle speed and operating power frequency, it has a larger value overall than the thrust from standard windings
