“…According to equation ( 8) and equation (10), the RF of each phase of the motor at an eccentricity of 20% is calculated as shown in Fig 3 . From Fig. 3, it can be seen that the effect of air gap eccentricity on the numerical change of torque of each phase is small, while the numerical change of RF presents the largest RF of phase B, the same RF of phases A and C, and the RF is close to unanimous for phases D and no eccentricity.…”

“…In recent years, most scholars have studied the problem of RF, and the literature adopt the two-dimensional Fourier transform method and the finite element (FEM) fixed-rotation coupled vibration analytical method, respectively, to analytically derive and verify the RF with the characteristics of the spatio-temporal distribution, and to reveal the main characteristics of the RF in the time domain and the frequency domain [9] [10] . These studies mainly focus on the mechanical properties of SRM under normal conditions and do not fully consider the changes in the mechanical properties of SRM under air gap eccentricity.…”

This paper analyses the negative impact of electromagnetic characteristics caused by air gap eccentricity in hub motor drive systems on vehicle dynamics. To further improve the vehicle dynamics performance. Firstly, the electromagnetic coupling equations and radial force (RF) equations are combined to calculate the changes in the electromagnetic characteristics of each winding phase under different eccentricities, and the RF measurement rig is designed and constructed to verify the accuracy of the numerical analysis calculation results. Secondly, the principle of longitudinal-vertical unbalanced radial force (URF) calculation is proposed, and the coupled dynamics model of the vehicle considering the URF is established to analyse the dynamic response characteristics of the vehicle under various working conditions. Finally, the structural parameters of the motor are optimized, and the optimal structural dimensions of the motor are obtained using the NSGA-II genetic algorithm, and the longitudinal-vertical URF is reduced by 11.68% and 6.81%, respectively, which effectively suppresses the negative influence of the electromagnetic characteristics of the wheel-hub motor drive system.

Aiming at the influence of radial electromagnetic force on vibration and noise of switched reluctance motor (SRM), the radial electromagnetic force under airgap eccentricity is represented based on the virtual displacement principle and Maxwell stress tensor. Multi-objective optimization of motor electromagnetic characteristics including magnetostatic torque, radial electromagnetic force fluctuation and unbalanced radial force amplitude is completed. Firstly, the analytical representation for the radial electromagnetic force is obtained by the virtual displacement principle and the expression of the unbalanced radial force caused by airgap eccentricity is deduced. Then, the spatial distribution of the radial electromagnetic force is modeled by Maxwell stress tensor, which makes the radial electromagnetic force characterization more comprehensive. In order to improve the electromagnetic characteristics of SRM under airgap eccentricity, sensitivity analysis and multi-objective optimization are carried out to obtain the optimal solution set of the motor structure parameters. The simulation results show that the radial electromagnetic force fluctuation and the unbalanced radial force amplitude decreases by 64.09% and 23.05% respectively when the magnetostatic torque is sacrificed by 6.36%, which provides a framework for multi-objective optimization of motor structure parameters.
