Abstract Switched reluctance motors are applied in electric vehicles due to their simple structure and low cost. The amorphous alloy used to the switched reluctance motor core can greatly improve efficiency of the motor. However, its large magnetostrictive coefficient and strong stress sensitivity (i. e. inverse-magnetostriction effect) will increase the core vibration and limit the precise control ability of electrical signals. Therefore, a new approach is proposed to use inverse-magnetostriction effect to control the electromagnetic vibration of switched reluctance motor with amorphous alloy cores (SRMA). Then, the compressive stress applied structure of the SRMA stator teeth is proposed. By comparing simulation results with the experiment, it shows that the vibration reduction method is feasible.
Firstly, to achieve a more accurate vibration analysis of a SRMA, a nonlinear magnetostriction and inverse-magnetostriction effect force-magnetic coupling constitutive relation of the amorphous alloy is proposed basing on the macroscopic thermodynamics, the parameters of this relation are measured by magnetic properties measurement system, the magnetostrictive strain and relative permeability of amorphous alloys with a magnetic field and compressive stress applied can be calculated on basis of the proposed constitutive relation. Secondly, the compressive stress applied structure of the SRMA is proposed based on the inverse-magnetostriction effect, a finite element model of the structure is established to verify the proposed structure’s stability. Then, according to the extended solution of the electromagnetic stress and magnetostrictive stress, a two-way dynamic electromagnetic-force coupling model of the SRMA considering the magnetostriction and inverse-magnetostriction effects is established. Finally, the experiments and finite element calculations are carried out on the vibration characteristics of SRMA. The magnetic flux density in the stator yoke area basically remained at 0.3T before and after the improvement, which shows that the SRMA can still maintain the original running state after the improvement. Furthermore, the finite element calculation results before and after considering magnetostriction of SRMA stator are compared, which shows that the main sources of vibration are magnetostrictive stress and electromagnetic stress, and among them the proportion of magnetostrictive stress in dynamic stress can reach up to 42.4%. Besides, after the stator teeth are applied to 24MPa compressive stress, the radial magnetic flux density near the bolt is significantly reduced due to the force-magnetic coupling, and the radial magnetic flux density and electromagnetic stress in the air gap are reduced by 26.3% and 44.5%, respectively. By comparing the vibration displacement results of the experiment and simulation, the spectral distribution is consistent, which verifies the accuracy of the SRMA model proposed in this paper.
The following conclusions can be drawn from the simulation and experiment analysis: 1) The proposed force-magnetic coupling constitutive relation of the amorphous alloy can simulation the magnetostriction and the inverse-magnetostriction effect, the nonlinear effect of stress on the relative permeability of amorphous alloys can be described more accurately. 2) By solving the two-way dynamic electromagnetic-force coupling model of the SRMA, the results show that magnetostriction effect cannot be ignored in vibration analysis of SRMA. 3) The compressive stress applied structure of the stator teeth can reduce vibrations while maintaining the original operation of the SRMA, it provides a new idea for research on the vibration reduction of SRMAs.
