Axisymmetric model of oscillations of the stator of an electric machine.

Abstract

An analytical model is described for calculating the mechanical axisymmetric oscillations of the stators of electric machines, taking into account the actual thickness, length, conditions of connection of the core and the housing. It is shown that with the help of the developed model it is possible to investigate new qualitative features of the vibration behavior of the stators of electric machines. The analysis of frequencies and modes of oscillations is given on the example of the stator design of the asynchronous motor AIR200L 4U3.
