Résumé

Compressors driven by inverters will produce high frequency noise, which will have adverse influence on total noise level. An existing compact inverter rotary compressor is studied in this paper and the effect of inverter carrier waves with Space Vector Pulse Width Modulation(SVPWM) technique on motor vibration and noise is analyzed and summarized. From order analysis and motor modal analysis, the results show that the high order harmonic current induced by inverter carrier wave will produce high frequency electromagnetic force, which will excite the stator into resonance, and finally leads to high frequency noise. The high frequency noise level is reduced by more than 5dBA after structural optimization of the motor.
