“…Since Dr. Genichi Taguchi [7] developed the Taguchi method, it has been used extensively in industrial optimization, including electrical machine applications. The existing motor optimization approaches based on the Taguchi method [8][9][10] are "point-like", where the designer chooses a fixed level for each factor and then selects the "optimal" value among known results. The level values of the factors are mostly subjective, which makes the optimization results more favorable to the designer's expectations.…”

The extensive use of finite element models accurately simulates the temperature distribution of electrical machines. The simulation model can be quickly modified to reflect changes in design. However, the long runtime of the simulation prevents any direct application of the optimization algorithm. In this paper, research focused on improving efficiency with which expensive analysis (finite element method) is used in generator temperature distribution. A novel surrogate model based optimization method is presented. First, the Taguchi orthogonal array relates a series of stator geometric parameters as input and the temperatures of a generator as output by sampling the design decision space. A number of stator temperature designs were generated and analyzed using 3-D multi-physical field collaborative finite element model. A suitable shallow neural network was then selected and fitted to the available data to obtain a continuous optimization objective function. The accuracy of the function was verified using randomly generated geometric parameters to the extent that they were feasible. Finally, a multi-objective genetic optimization algorithm was applied in the function to reduce the average and maximum temperature of the machine simultaneously. As a result, when the Pareto front was compared with the initial data, these temperatures showed a significant decrease.

This paper explores the feasibility of an intuitive solution torque density for the existing brushless doubly-fed generator by dual-stator and cage-barrier rotor structure, so as to better adapt to the offshore wind power generation. The torque density of electrical machine is related to the key design parameters, such as the machine main dimensions, slot-pole combinations, coupling between stator and rotor, and nonmagnetic ring thickness. According to working principles and design requirements of electrical machine, the dual-stator brushless doubly-fed wind power generator (DSBDFWPG) with cage-barrier rotor is designed, and the key parameters relating to torque density are analyzed and discussed. Meanwhile, the main parameters of electrical machine are optimized by Taguchi method, such as air-gap length and nonmagnetic ring thickness. On this basis, the performance parameters of DSBDFWPG are analyzed by finite element method, which is verified by experimental tests. Through analysis of the results, not only the design requirements are satisfied by the DSBDFWPG, but also the correctness and rationality of machine design method can also be verified. Finally, the torque density and other aspects of designed DSBDFWPG are compared with dual-stator brushless doubly-fed induction generator, doubly-fed induction generator, asynchronous machine, and brushless doublyfed generator; it demonstrates the torque density improvement of the studied machine with its significance and value. KEYWORDS brushless doubly-fed machine, dual stator, electromagnetic design, optimization, torque density, wind power generator 1 | INTRODUCTION Because of the rapid development of wind energy in recent years, wind power becomes one of the main new energy powers. According to thelatest data from the Global Wind Energy Council, the global installed capacity is 486.7 GW, and the new installed capacity 1 is more than 54.6 GW in 2016. It is also observed that wind-generated electricity is valued by all countries. So far, the wind-generated electricity is mainly based on land, which has the disadvantages of regional limitation and wind speed instability. Thus, people began to seek from the land to offshore wind power. The wind energy resource developed by offshore wind farm is three times of that by the land wind energy resource. Meanwhile, the offshore generating capacity is 20% to 40% higher than that of the land. Compared with the land wind energy, the offshore wind energy has advantages with rich reserves, good stability, high wind speed, and easy prediction. 2,3 Therefore, the offshore wind power generation has become

This paper uses the Taguchi method to optimize the manufacturing process and robust design of a low-cost permanent magnet motor with soft magnetic composite (SMC) cores. For the manufacturing process, SMC cores are produced by using the molding technology without any wire cutting costs. To maximize the relative permeability and minimize the core loss, the Taguchi method is employed to identify the best control factor values for the heat treatment of SMC cores based on a series of experimental results. Due to the manufacturing tolerances, there are significant uncertainties in the core densities and motor dimensions, which will result in big performance variations for the SMC motors in the batch production. To obtain a robust design less sensitive to these tolerances, the conventional Taguchi parameter design method and a sequential Taguchi optimization method are presented to maximize the average torque and minimize the core loss of a low-cost PM motor. Through comparison, it is found that the proposed optimization method is efficient. It can provide an optimal design with better motor performance and manufacturing quality. The proposed method will benefit the industrial production of cost-effective PM-SMC motors with robust and compact designs.
