摘要
Abstract
The finite element method was used to analyze the dynamic characteristics (such as shapes,natural frequencies) of the stator structure of high speed induction motor.The analytical method and the finite element method were used to analyze the electromagnetic force wave of the motor under the rated speed 60 000 r/min.Harmonics of radial air gap flux density and radial electromagnetic force wave were analyzed by Fourier transform.And the harmonic amplitudes at different frequencies were obtained.The electromagnetic force wave were added to the corresponding node of the motor stator.Electromagnetic vibration and sound field of high speed induction spindle motor were analyzed.The electromagnetic noise of the motor under no-load and load conditions was calculated.关键词
