Optimum Design of a Five-Phase Permanent Magnet Synchronous Motor for Naval Applications using Bees Algorithm

Multi-phase motors are increasingly used in electrical systems due to their benefits such as decreased current without decreasing voltage, decrease of DC link current and improved reliability. Major applications of such motors are naval systems, electric vehicles, spacecrafts and etc. besides, permanent magnet motors has gained researchers’ attention due to their simple design, high efficiency and power density, low volume and weight and minimum loss and noise.However, electrical motors companies are under pressure and they have to present devices with minimum financial charges. The first and the most important aspect in electrical machines design is to decrease the volume and weight and consequently improve their power density and efficiency. In other word, improvement is done by optimizing machines’ dimensions.This thesis presents design optimization of five-phase permanent magnet synchronous motors to use in underwater vehicles. For this purpose, motor is optimized using optimization Bees algorithm (BA) to have less volume and weight and best operational characteristics. Then, motor is simulated using Ansoft Maxwell which is based on finite element analysis. This software gives required information about performance of the motor. Finite element analysis is an accurate and valid method which is used extensively in analyzing such problems.
