Abstract：The current research status of electromagnetic vibration and noise suppression methods of automotive permanent magnet synchronous machine at home and abroad is reviewed,focusing on three aspects of reducing motor vibration and noise,namely,the amplitude of motor electromagnetic force,the structural modulus and intrinsic frequency of the stator system,and the introduction of carrier vibration and noise in the inverter.Reliable methods for reducing motor vibration and noise are reviewed,followed by examples of acoustic and psychoacoustic factors for evaluating motor vibration noise,and future development trends are summarized to provide references for subsequent research on vibration noise suppression of automotive permanent magnet synchronous motors.
