Modeling of salient-pole synchronous motor considering saturation effect

Saturation effect plays an important role in high performance salient pole synchronous motor control system and the linear magnetic model can hardly depict the static and dynamic characteristics of the motor accurately. In this paper, the magnetic saturation phenomena are characterized by static saturation inductances, dynamic saturation inductances and cross saturation inductances, based on which the saturated silent pole synchronous motor model is established. Field oriented control algorithm is applied in the synchronous motor controller to analysis the saturated model. Simulation results indicate that the main physical variables act in according with the motor operating principles under saturated magnetic situation and thus the validity of the model is verified.
