“…The switched reluctance motor (SRM) has attracted extensive attention in aeronautical facility, electric vehicle, household appliance, and other fields by virtue of its low cost, simple control, and stable mechanical structure. 1,2 However, the further development is limited by its vibration and noise problems during operation. Particularly, the radial electromagnetic force acting on the stator/rotor salient pole of the motor is the main source of vibration and noise.…”

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.

“…In [22], a semi-active vibration control strategy for IWSRM was proposed based on a dynamic vibration absorbing structure to effectively improve ride comfort and reduce the SRM vibration. In [23], for reducing the SRM vertical vibration, a linear quadratic gaussian controller was proposed for electromagnetic active suspension to suppress the unbalanced radial force. On the other hand, various dynamic vibration absorbing structures are presented to improve dynamic performance of integration system.…”

The in-wheel switched reluctance motor (IWSRM) has significant potential for utilization in electric vehicle (EV) because of its inherent advantages such as low cost, robustness, wide speed range, and direct drive mode. However, the unbalanced radial force caused by eccentricity of IWSRM results in increasing vehicle vibration and decreasing riding comfort. In this paper, various vertical vibration control strategies for IWSRM are proposed and compared to improve the vibratory behavior of vehicle. First, effects of eccentricity ratio and eccentric angle on radial force, torque, and inductance are investigated by numerical analysis method for IWSRM. Then, IWSRM model, vehicle model, and suspension model are developed, based on which two common control algorithms (i.e. CCC and PWM) are provided and used as benchmarks to compare with the newly proposed two (i.e. CCC-F and PWM-F). They are designed by introducing the vehicle vertical acceleration as an extra control objective. Finally, the dynamic response of four control strategies are analyzed and the comparison results show that each of them performs differently under different driving conditions. As a result, a switchable controller based on the proposed control algorithms is presented to improve the overall performance of the IWSRM for EVs under various driving modes.
