This study presents a design method of a linear transverse-flux machine with mutually coupled windings aiming at the force ripple optimisation. Considering the three-dimensional (3D) magnetic flux in the proposed machine, a mathematic model based on Maxwell stress tensors is developed to facilitate the optimisation, so that the objectives depending on the selected design parameters can be analytically calculated. In order to reduce the optimisation time of the complex machine, mostly influential design parameters are evaluated by the Taguchi method first. Furthermore, the selected parameters are optimised with the human group optimisation algorithm. The main purpose of the algorithm is to attain the desired electromagnetic force with the minimum force ripple coefficient under the restriction of the overall volume. The proposed optimisation has been applied for a case study, and the final design is compared with that optimised by the genetic algorithm. The results show that the optimal machine design obtained by the proposed method has the lower force ripple coefficient, which is also verified by the 3D finiteelement method and experiments.

“…The evolutionary strategy algorithm, Kriging meta-model, and multi-step optimisation are used to optimise this separated permanent magnetic PMA in [24,25]. The design method, with the Taguchi method and dynamic characteristic analysis, is presented for the unsymmetrical bistable PMA with magnetic barriers [26]. To increase the long stroke of the PMA, the moving coil unsymmetrical bistable PMA (MCUBPMA) is presented in [27].…”

“…However, the holding force in the open stage is over the need of HVCB, which increases the wastage and closing time. Thus, the unsymmetrical structure bistable PMA (USBPMA) is proposed, which overcomes some of the disadvantages of the SSBPMA, such as the large retention in the opening state, and large closing current [22][23][24][25][26][27][28][29]. However, the USBPMA also has defects, such as a low initial speed.…”

In this study, an unsymmetrical bistable multi-magnetic circuit permanent magnetic actuator is proposed. The operating principle and mathematical model of the high-voltage circuit breaker with the proposed machine are analysed. Additionally, the static and dynamic characteristics of the high-voltage circuit breaker with the presented machine are investigated and evaluated using numerical finite element analysis methods. Furthermore, the influence of the length of the middle gap and the additional coil in the proposed machine are studied. The advantages of the presented machine, such as less magnet volume, low cost, high force density, and short starting time, are discussed. Finally, a prototype is created and tested, followed by the retrieval of the characteristic curves of the holding force to confirm the proposed design.

“…Additionally, some optimization work was done to improve the performance of PMAs. In reference [14], the Taguchi method was used to screen out the relatively more influential design variables and speed up the optimization process. Optimization algorithms (including heuristic random searching algorithms and conjugate gradient method) combined with finite element analysis (FEA) were used to optimize the PMAs in references [15,16].…”

Multi-Objective Optimization of a Permanent Magnet Actuator for High Voltage Vacuum Circuit Breaker Based on Adaptive Surrogate Modeling Technique

A novel mono-stable permanent magnet actuator (PMA) for high voltage vacuum circuit breaker (VCB) and its optimal design method are proposed in this paper. The proposed PMA is featured with a structure of separated magnetic circuits, which makes the holding part and closing driving part work independently without interference. The application of an auxiliary breaking coil decreases the response time in the initial phase of opening operation, and an external disc spring is adopted to accelerate the opening movement, which makes the PMA meet the fast-breaking requirement of high voltage VCB. As calculating the characteristics of the PMA accurately through numerical simulation is a time-consuming process, a multi-objective optimization (MOO) algorithm based on surrogate modeling technique and adaptive samples adding strategy are proposed to reduce the workload of numerical simulations during optimization. Firstly, initial surrogate models are constructed and evaluated, and then iteratively updated to improve their global approximating abilities. Secondly, according to the approximate MOO results obtained by the global surrogate models, additional samples are added to constantly update the surrogate models to gradually improve the models’ local accuracies in optimal solution regions and finally guide the algorithm to the true Pareto front. The efficiency and accuracy of the proposed algorithm are verified by test functions. By applying the optimization strategy to the design of the proposed PMA, a set of satisfying Pareto optimal solutions, which improve the overall performance of the PMA obviously, can be derived at a reasonable computation cost.
