Modification Genetic Algorithm for Topological Optimization the Rotor of Synchronous Motors

Abstract

The aim is to develop a procedure for topological optimization of the rotor design of permanent magnet synchronous motors. This method is more accurate than the traditional analytical methods used in the analysis of AC machines and takes less time than the usual trial and error design procedure based on the finite element method. The main optimization criterion is an increase in torque while maintaining the mass of the most expensive material (permanent magnets), and an important point will be to check the resulting structure for thermal and strength characteristics. This feature is important for manufacturing the engineered engine in production. Thus, topological optimization is based on the method of modifying the rotor design using a genetic algorithm with the additions necessary for correct operation with synchronous motors.
