Abstract
In order to reveal the influence of current time harmonics on the electromagnetic vibration and noise of the motor,the radial electromagnetic force of the permanent magnet synchronous motor(PMSM)fed by frequency converter is analyzed and calculated with Maxwell stress equation,the order and frequency of radial electromagnetic force are analyzed theoretically.It is pointed out that the electromagnetic vibration and noise produced by the motor in low frequency and middle-high frequency can be aggravated by the power supply of the inverter.Taking a 48-slot 8-pole permanent magnet synchronous motor as an example,the electromagnetic finite element model and structure finite element model of the motor under the condition of inverter and sine wave power supply are established respectively.The vibration response and noise change of the motor under these two power supply modes are compared by ANSYS multi-physical field simulation,and the correctness of the analytical analysis is verified.关键词
