“…The Taguchi optimization algorithm, which is adept in the use of discrete results to identify the optimal point, has been widely used in many areas, e.g., national defense, chemical, and motor applications [ 23 ]. The orthogonal array (OA) and the signal-to-noise(S/N) ratio are the main tools used in this method [ 24 , 25 , 26 ]. The former was applied to design representative experiments and shorten the number of required hours.…”

For the optimization of three-phase hybrid stepper motors with complex electromagnetic structures, an optimization method is presented in this paper. The method is a combination of 3D-FEM and the Taguchi optimization method intended to reduce the dependence on FEM results during the optimization calculation. In this paper, the optimization method is used in the optimization of the tooth shape of the three-phase hybrid stepper motor, and the objective is to reduce the noise caused by harmonics in the “torque-angle characteristic” of the motor. It is clear that traditional optimization methods make it very difficult to carry out such an optimization calculation as a large number of finite element calculations have to be used in the optimization process, and the required computation time is extremely long. Using the optimization method presented in the paper, the optimization becomes feasible because the number of finite element calculations is greatly reduced and the computation time is thus greatly reduced. In order to check the effectiveness of the optimization, the waterfall diagram for noise analysis and its application to check torque ripple are also presented in the paper. Both simulation and test results show that the optimized structure can significantly reduce the motor noise caused by torque ripple. Therefore, the optimization method proposed in this paper can be an effective tool for the optimal design of high-performance motors, including stepper motors.

“…In order to suppress the alternating-current harmonics and maintain the simplicity for the current loop, many researchers have attempted to optimize the current loop controller through resonant control theory and model predictive control theory [12][13][14][15][16]. Additionally, RC strategy and other control strategies are also used to simplify the complexity of the control system [17][18][19][20][21][22].…”

Compared to the proportional-integral strategy, the repetitive control strategy possesses high suppression ability for the alternating current (AC) harmonics of control signals. Thus, RC controllers are widely used in closed-loop control systems to suppress the periodic harmonics. In order to further improve the brushless DC (BLDC) motor operation performance, a frequency adaptive repetitive controller (FARC) is proposed, and then a novel current loop scheme that concatenation of proportional-integral controller (PIC) and FARC controller is established in this paper. Firstly, due to the real sampling number of the delay element in the BLDC, the motor control system may not be an integer, the designing process of the FARC parameters was studied, and an adaptive internal model controller and a novel decomposition rule for FARC were designed based on Lagrange interpolation theory. Secondly, the PIC parameters were analyzed through three-dimensional and two-dimensional images of the frequency characteristics. Furthermore, a composite controller that added a forward channel in the novel current loop was proposed, and the stability of the control system used the composite controller was analyzed through Lyapunov theory. It should be noted that the analysis of FARC mainly focused on the simplified structure and the parameter optimization, which is usually ignored in the previous studies. Finally, the BLDC motor control system model was established through Matlab/Simulink software, and the operation performances of the BLDC motor control system utilizing different current loop controllers were studied. The simulation results show that the proposed FARC can reduce current distortion and torque ripples, thus, the BLDC motor operation performances can be improved effectively.

The imperative shift toward sustainable development mandates a revolutionary transformation in the transportation sector. While the transition from internal combustion engines to electric motors represents a pivotal step, its ecological impact may fall short of expectations. This undertaking is motivated by the recognition that a truly impactful transition necessitates intricate strategies, addressing resource consumption during manufacturing and minimizing post-use waste. This literature review is dedicated to enhancing the framework of circular strategies within the realm of electric motors, with a specific focus on remanufacturing. The objective is to cultivate a conscientious approach to product development, primarily centered on the four key pillars of circularity: reuse, remanufacture, upgrade, and recycle. The primary goal is to furnish a comprehensive overview of the myriad possibilities associated with reusing products, either in parts or as a whole. Upon introducing the circular approach, this review underscores pivotal enabling technologies essential for a successful transition. These include inspection, disassembly, rewinding, and demagnetization. The ensuing discussion delves into the technological challenges faced and presents cutting-edge solutions poised to redefine the landscape. The concluding section extends the perspective to the future, introducing innovative studies and solutions still in their developmental stages. This review is tailored for decision-makers, policymakers, and researchers, providing them with a valuable overview and facilitating discussions to propel our society toward a sustainable and responsible future in electric motor technology.
