A model for saturation effects in high-field permanent magnet synchronous motors

A procedure is proposed to study and identify the model of a buried permanent-magnet synchronous motor which takes account of the nonlinear magnetic phenomena caused by the armature current. The experiment procedures are described, and the results of the measurement of the parameters of the linear d-q model of the motor considered are presented. A simple procedure is then proposed for using finite elements to study the saturation phenomena found, and the relative model is defined. A comparison between the experimental and simulation results shows them to be in good agreement.<
