Effect of Cleaning Level on Topology Optimization of Permanent Magnet Synchronous Generator

摘要

We propose a topology optimization method that incorporates the concept of the cluster and cleaning method in a genetic algorithm. This method can be used to design a rotor structure with high output power and low permanent magnet volume from an empty space. In this study, the effect of the level of the cleaning method on the obtained rotor structure is investigated. A permanent magnet synchronous generator is designed using the optimal level of the cleaning method. This generator has higher output power characteristic with low permanent magnet volume than a generator used in Prius, which is a general hybrid vehicle.
