Simple models of synchronous machines are studied for torsional vibration analysis of electrically driven drive trains. A non-linear system model of the electrical machine is derived based on the two-axis equations. It is linearized to a small-signal model. The validity of these models is studied by comparing their results with the results from time-discretized finite element analysis. Four types of synchronous machine under torsional vibration are used as test cases. The results of the small-signal two-axis model show good agreement with the results of finite element analysis. All the three models predict negative damping of torsional vibration over a wide frequency range from zero to the supply frequency for all the four test machines.
