Description
This paper deals with the quenching problem of vibration of the inverter motor stator caused by the rotating distributed electromagnetic force by using both Houde dampers and added mass. The solutions of forced vibration are obtained by the finite element method and the ring theory. The following were made clear; (1) By setting two Houde dampers and single mass on the stator, the vibration of motor stator is quenched over wide frequency region around resonance. (2) By setting single Houde damper and single mass, the vibration of motor stator is quenched also. (3) The results by the ring theory coincide with those by the finite element method qualitatively. (4) The maximum difference between the amplitudes obtained by the finite element method and those by the ring theory is almost 10%.
