Hopf bifurcation in the study of synchronous motor stability

In this document the dynamic model of the synchronous motor is presented, which has a typical structure of Lienard-type systems, the theory of dynamic systems is used, especially bifurcations, in this case, Hopf’s, which will be applied to the described model, to show the variations in the balance points of the system by taking the voltage of the bus to which it is connected as a variable parameter.
