Vibration modeling of the two-speed, large power, synchronous motor

Abstract

In this paper the calculation results of a two-speed synchronous, silent-pole, large power motor, are presented. Using the FEM tools, the two dimensional, field-circuit model (for electromagnetic calculation) and two-and three-dimensional mechanical models, for the large power motor, type GAe 1510/12 p were examined. The simulations, for load, for both rotational speeds, were conducted. The target of application of discussed analysis is the vibration behavior of the machine.
