Abstract :
A 2-dimensional shape optimization method for magnetic materials and conductors such as those of induction machines has been developed. The method combines a steady state AC field analysis based on complex expressions of magnetic fields, a method to compute Lorentz force in complex form and the direct search method. As an example, shape optimization of a single sided linear induction motor is reported
