“…Some of the topology optimization methods were proposed approximately twenty years ago (1) (2) . Since then, several papers have been published in this field, for example, Takahashi et al proposed a topology optimization using ON/OFF method (3) , Okamoto et al proposed a genetic algorithm (GA) and design space reduction (4) , and Sato et al proposed topology optimization using normalized network (5) . The authors also proposed a topology optimization method to optimize the material distribution of electrical machines using the GA (6)- (8) .…”

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.

This paper designs the rotor structure for two types of permanent magnet synchronous motors. The proposed optimization method combines a topology optimization method, which uses a genetic algorithm and a cleaning procedure, and a method considering ease of manufacturing. The designed rotor of a compressor motor for an air conditioner has 32% higher average torque than that of a conventional motor. The designed rotor has a larger torque/current than that of a hybrid vehicle motor at a low output power.

This paper presents the shape optimization of magnet and flux barriers in the interior permanent magnet synchronous motor (IPMSM). Authors use the polygon model method with genetic programming (GP) by the twodimensional finite element method (2D-FEM). In this method, the analysis model of IPMSM is regarded as a tree structure. This method optimizes a shape by operating tree structures with GP. The tree structure of this method is possible to express every shape. Therefore, this method can obtain an optimal shape without being bound by a stereotype. The purpose is the investigation of shape design of magnet and flux barriers to improve the electromagnetic characteristics. Additionally, authors take into consideration about complexity of shape and volume of magnet.
