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 reduced
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 proposed method.
