Modeling of asynchronous motor vibrations

A mathematical model of dynamic processes in asynchronous motors that takes into account interrconnection between electromagnetic phenomena in electric machine and mechanical oscillation is considered. For motors of the most common designs, it is assumed that the axis of rotation of the rotor relatively to the stator is immovable; the stator is based on flexible supports. The results of calculations of vibration processes in asynchronous motors are presented. In particular, the influence of stiffness-dissipative parameters of stator supports on the maximum values of forces in stator supports and the angular displacements of the stator are analyzed.
