Abstract

This paper analyzes the electromagnetic vibration sources affect mechanical vibration the PMSM type motor for full electric driven compressor of electric vehicles. 2-D FEM solutions for cogging torque, torque ripple and radial force density are obtained magnetic field solutions. And find natural frequencies the stator of this electric machine using 3-D FEM. Finally, compare vibration sources from electromagnetic harmonics with natural frequencies stator of the motor.
