“…Taguchi [19] introduced the quality loss theory into the product design and manufacturing process for establishing the tolerance design model, and took the output characteristic and its fluctuation as the basis for calculating the cost loss [20][21][22]. Later, scholars combined the cost and performance to establish the comprehensive quality loss function [23][24][25]. The abovementioned methods are suitable for the tolerance design of electronic system, since it is easy to estimate the cost of each component.…”

Electromagnetic devices (EMDs) containing permanent magnets are common devices showing low power consumption , small size, and high sensitivity. In batch production of EMDs there is a robustness problem linked to the migration of the working point of permanent magnets and to their manufacturing uncertainties. In turn, the design optimization for EMDs has attracted large attention. Robust design optimization (RDO) is one of the most effective methods to boost quality and robustness of EMDs. However, state-of-art RDO methods ignore the various uncertainties from manufacture processing, production environment, and working point migration of permanent magnets. To address those problems, this study presents an efficient and universal method based on the working point migration and various uncertainties of output characteristics for electromagnetic devices. At first, we introduce a two-dimensional factor design scheme considering the working point migration and manufacturing conditions. Then, a robustness assessment measure suitable for different optimization types is proposed. On these bases, the optimization model is established, considering the permanent working point migration for magnets, manufacturing tolerances and robustness constraints, and a particle swarm algorithm is used to obtain the solution. Finally, the effectiveness of the method is verified by a case study involving a specific type of electromagnetic device with permanent magnets.

“…Owing to no symmetry along the z ‐axis of the RHFHM structure, determining the field distribution is very complicated in the two‐dimensional (2D) coordinates. Hence, to obtain the field distribution of the proposed RHFHM and consequently calculate the output parameters, a method based on superposition theorem [15, 16] is proposed. Whereas the stator yoke for the flux passage is same in both axial and radial parts of the RHFHM, by considering a linear magnetic characteristic of the stator material (using the linear part of the B–H curve in the analysis process), the analysis can be divided in two axial and radial parts and the results can be summed up.…”

The performance analysis of a hybrid hysteresis motor using an analytical model is presented in this study. The proposed hybrid motor benefits fromthe advantages of both the conventional axial and radial flux hysteresis motors with a unique stator. For the design of the proposed machine, a pre‐studied hybrid hysteresis motor is investigated. To modify the field equations, the hyperbolic approximation of the hysteresis loop is implemented to investigate the effects of the minor loops described by the harmonic components of the field. Next, the impact of the harmonics of the magnetomotive force on machine performance is estimated by an iterative approach. Then, the closed‐form expressions for the developed torque are obtained in both planes and the results are stacked‐up linearly by considering the basics of the superposition theorem. To evaluate the performance of the proposed machine and also the accuracy of the analysis approach, a laboratory prototype has been built. The test results validate the acceptable performance of the proposed hysteresis motor.

“…Although the non-probability model improves the optimization effect, it neglects correlations of uncertainties. In order to further improve the optimization effect, scholars have proposed an improved uncertainty quantitative method [18][19][20][21][22], which solves correlations of uncertainties to some extent, but these methods are only effective in a certain distribution and for linear design parameters. In addition, it should be pointed out that these methods only consider uncertainties from the manufacturing process and operational environment, optimize the initial quality, and ignore the degradation progress.…”

To better qualify various uncertainties in design and manufacturing, as well as to understand the time-varying degradation process, a novel method of quality and reliable design and optimization for high-power DC actuators was developed in this study that considered relevant uncertainties in design, manufacturing parameters, and the degradation process. Orthogonal transformation was used to normalize heterogeneous uncertainties and the results were quantitatively described by the hyperellipsoid set model. On the basis of the uncertainty quantitative relationship, a fast substitution model was developed for high-power DC actuators with permanent magnet output characteristics of strong non-linearity and insufficient accuracy. The response surface method was used to derive the basis function, and the error between the practical measured values and the calculation values was modified by the radial basis function model. Afterwards, a life cycle global sensitivity analysis method was put forward to determine the design parameters when parameter degradation existed during the life cycle of high-power DC actuators. Then, an optimization model was established considering parameter uncertainties and reliability constraints, and the particle swarm algorithm was used to obtain the solution. Finally, the effectiveness of the proposed method was verified by a case study of high-power DC actuators in electric vehicles.
