This paper deals with the dynamic characteristics of permanent magnet synchronous motors(PMSM). The steady state characteristics of these systems,subject to constant input voltages and constant external torques,are formulated. Furthermore,three cases are discussed and at each case we discussed the condition on which the dynamic characteristics of the system are steady or chaotic. In addition, we propose a method to adjust some parameters so that the system exhibits limit cycle(LC) or chaotic behavior. Finally,computer simulations are presented that verify the existence of strange attractors in the permanent magnet synchronous motors(PMSM).
