ABSTRACT
Noise suppression is one of the important issues to be solved in the motor design and application. Dominant electromagnetic noise in the low-speed case, magnetostrictive force account for a large proportion for the generation of electromagnetic noise and vibration and this phenomenon is particularly prominent in large motors. In this study, the impact of the rotating magnetic field to magnetostrictive properties of the permanent magnet motor stator core is analyzed. Through the quadratic moment domain rotation model, a rotating magnetic field of the magnetic-mechanical coupled numerical model is built. Under the permanent magnet motor stator boundary conditions, the electromagnetic field distribution is constructed, stator cores magnetostrictive stress, strain and displacement are calculated by FEM and the distribution of stress is obtained on the permanent magnet motor stator teeth. This study provides an effective numerical method for the design of large-scale high-performance permanent magnet motor with low noise.
