Abstract：The suppression of vibration and noise is a hot research field of switched reluctance motor in recent years. Based on Maxwell tensor theory, the principle of reducing radial magnetic tension was analyzed in this paper. By cutting rectangular slots at the top of stator teeth and on both sides of rotor teeth at the same time, the length of air gap between stator and rotor was increased, and a part of magnetic flux density along radial direction changed into along tangential direction, which could reduce the radial magnetic tension and achieve the purpose of restraining electromagnetic vibration. Using the parametric scanning method, the slotting parameters were optimized, and the radial magnetic pull force of motor before and after slotting were compared and analyzed. The modal, harmonic response and noise of the motor stator before and after slotting were analyzed by ANSYS Workbench module, and the modal natural frequency, modal participation factor, vibration response frequency and sound pressure spectrum were obtained. The results show that this method can effectively reduce the radial magnetic pull force of switched reluctance motor and improve the vibration and noise of switched reluctance motor.
