Dynamic Analysis and Experiment Research of Stator Vibration for BLDC Motor
Motor is one of the main sources of vibration and internal and external noise in the electric vehicles(EV). Therefore, designers are expected to can predict vibration and noise performance in the design stage of motor. Based on the finite element analysis of electromagnetic field theory, the radial force wave of permanent magnet brushless dc motor used in vehicle is studied by simulation and calculation;Then a dynamics model of motor stator is discussed by stimulation, which achieves the goals to analysis the vibration of motor stator. The simulation results are proved by motor vibration experiment results, which verify the correctness of the analysis and lay a foundation for optimization design of the low noise motor in the future.
