This paper outlines a method for forecasting noise, vibration, and harshness in permanent magnet synchronous motors. It does this by carefully connecting those harmonic-rich excitation currents to the stator vibrations and the acoustic noise that follows. At the heart of the approach, there are two main computational stages. First, you create a harmonic-rich flux density pattern with a basic air-gap magnetomotive force model. Then, you apply the Maxwell stress tensor method to figure out the instant pulsating radial electromagnetic forces. In the second stage, that force serves as the input for a simple single degree of freedom model of the stator. From there, you solve the equation of motion through state-space simulation to get the mechanical response. The outcomes really back up this predictive setup. They show a strong link between the input current harmonics and the frequency peaks in the simulated force and acceleration spectra. All of this proves how useful the method is for handling key NVH issues right in the design stage of high-performance electric drives.
