Abstract:
 Abstract:In the motors fed by the PWM voltage source inverters,time harmonics introduced by the inverter switching processes,contribute to the motor vibrations and acoustic noise. A carrier phase shifted
approach was proposed to reduce the vibration of a permanent magnetic synchronous motors(PMSMs) fed by dual PWM inverters. The carrier phases between the dual PWM inverters were adjusted to control the voltage harmonics. The time harmonics of the stator magnetomotive force excited by the corresponding current harmonics were eliminated and the radial pressure is depressed. Consequently,the vibration and acoustic noise were deduced. Without more hardware investment the vibration and acoustic noise were re-
duced greatly and the method is easily implemented. The carrier phase shifted method can have a 18 dB impact on the vibration acceleration. The theoretical analysis and simulation results validate the correction and effectiveness of the nronosed method.
