Abstract :
The vibration and acoustic noise of PM machines by inverter are investigated in this paper. The main work includes calculation of 3-D magnetic field and sound field with the effect of higher time harmonics; the noise experiment effect of varying the switching frequency is explored and analyzed; The method for calculation 3-D sound field with the influence of switching frequencies is mentioned, and the calculating results agree with the measured one. The experiment of changing the switching frequency is completed, and the suitable switching frequencies for axial flux PM machines are determined.
