Recently, research on electrified aircraft engines is receiving increased attention, with the aim to reduce emissions and noise in civil aviation. One key component of novel electrified aircraft engines is the electric motor. As motors with the required power density are not available yet, it is reasonable to predict and to optimize the noise and vibration of such motors through detailed numerical simulations. In this study, an 8-pole and 48-slot interior permanent magnet synchronous motor is used as a case study to demonstrate the capability of such simulations in predicting electric motor noise.Electromagnetic vibrations caused by the radial electromagnetic stress within the air-gap are a key factor to generate the motor noise. In a first step, the radial electromagnetic stress in the air-gap is obtained based on the Maxwell stress tensor method in conjunction with electromagnetic simulation applying finite element analysis. Second, the calculated electromagnetic stress spectrum is used as the excitation source for a structural harmonic response analysis based on the mode superposition method. Third, the sound pressure is determined assuming 2D free-field radiation. The multi-physical model established in this paper provides a useful model for predicting motor noise in future electric aircraft propulsions. Scaling the results to higher force density will be addressed in future research.
