摘要：
Overcoming the shortcomings of the analytical method and the finite element method in the calculation of electromagnetic force waves, this paper proposed a fast and accurate calculation method for electromagnetic force waves. The static field solver in the finite element software was used to determine the magnetomotive force and air-gap permeance with two finite element simulations, and then obtain the amplitude of each electromagnetic force wave with specific order and frequency. In addition, considering the influence of the stiffness of the stator teeth, this paper calculated the natural frequencies of multiple stator cores, and summarized the fast and accurate equivalent formula for the stator cores. Taking a 6-pole 36-slot variable-speed permanent magnet synchronous motor as an example, the natural frequencies corresponding to its radial modals were analyzed, and the finite element method and the hammer method were used to verify the accuracy of the calculation results. Based on this, this paper predicted the vibration characteristics of the stator with enclosure and verified it by the finite element method. Using the fast and accurate calculation method of electromagnetic force wave and the fast equivalent formula of stator core established in this paper can quickly and accurately predict the vibration characteristics of the stator, which provides convenience for the weakening of electromagnetic vibration in the motor design stage. © 2021 Chin.
