First, using the analytical method to estimate the natural frequency of a permanent magnet synchronous motor core, the focus of the winding and the winding end of the natural frequency of the motor, respectively, the finite element method and experimental modal analysis method verify the correctness of the analytical method, this article resolve modal analysis method in the motor design stage can be used to quickly estimate the natural frequency of the motor.
