Abstract :
The paper deals with the acoustic effects of modern VSI-fed induction motor drives. The chosen testing method, extensive experiments using typical industrial frequency converters and the results of wide noise harmonic analyses are presented. The paper shows connections between the inverter type (PWM-type, modulation frequency) and the noise effects (spectrum, sound pressure) at various drive frequencies. It can help in the choice of the correct inverter solutions in view of acoustic compatibility of the drive. The noise spectrum analysis can be also, as shown, used for diverse diagnostic purposes
