“…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) . In the method, the concept of the cluster of material and cleaning procedure has been proposed, which can remove small pieces of iron scattered in the air and in the permanent magnet (PM), and remove small structural spots in the iron and in the PM.…”

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.

The objective of conventional topology optimization is to optimize the material distribution for a prescribed design domain. However, solving the topology optimization problem strongly depends on the settings specified by the designer for the shape of the design domain or their specification of the boundary conditions. This contradiction indicates that the improvement of structures should be achieved by optimizing not only the material distribution but also the additional design variables that specify the above settings. We refer to the additional design variables as external variables. This paper presents our work relating to solving the design problem of topology optimization incorporating external variables. The approach we follow is to formulate the design problem as a multi-level optimization problem by focusing on the dominance-dependence relationship between external variables and material distribution. We propose a framework to solve the optimization problem utilizing the multi-level formulation and metamodeling. The metamodel approximates the relationship between the external variables and the performance of the corresponding optimized material distribution. The effectiveness of the framework is demonstrated by presenting three examples.

“…During the iterative optimization process, the shapes of rotor poles, represented by zero-level sets, are simultaneously optimized by redistributing the iron and magnet material over the design domain. Ishikawa [5] proposed optimization method combines a topology optimization method, which uses a genetic algorithm and a cleaning procedure, and a method considering ease of manufacturing. Putek [6] presented the topology optimization method to design the rotor and the tooth base in the stator of the PM excited machine with the improved high-speed features.…”

Determining the rotor design parameters of alternator has great importance to provide the desired efficiency and magnetic flux distribution. In this paper, topology optimization of rotor structure in permanent magnet alternator is studied to provide these goals. For this purpose combinations of different diameter and height values are used to determine the optimum rotor design. Solidworks and Maxwell simulations are used for data collection. The solution of this design problem shows that how the diameter and height values affects the performance of the alternator. As a result, the efficiency of the alternator is improved under the desired magnetic flux conditions.
