In this study, we experimentally investigated the vibration generated in the housing of a permanent magnet synchronous motor and proposed a design guideline for reducing this vibration by establishing a finite element model of the motor. We acquired the frequency spectra of the vibration signals at various rotational speeds of the motor and identified the excitation frequencies induced by the electromagnetic force of the motor. In addition, the natural frequencies and mode shapes of the motor were obtained through modal testing, and an operational deflection shape analysis was conducted to analyze the dynamic behavior of the motor during operation. The resonance of the motor housing was identified using signal and dynamic characteristic analyses. To reduce vibration, a finite element model that considered the main components and structure of the motor was established, and a vibration reduction method was proposed that involved improving the motor housing structure.
