Abstract :
The shape design of stator slot of 3-phase cage induction motors for iron loss reduction is presented. For optimum shape design, the sensitivity analysis by discrete approach is employed and the gradient projection method for nonlinear constraint problems is chosen for an optimization algorithm. The 2D finite element method with voltage source is used to find the flux distribution in induction motors
