Abstract:An engineering recognition method of the mutual inductance is raised through the deduction of the state equation of induction motors considering the main flux saturation and iron loss in an arbitrary rotary coordinate frame, and through the study of the changing law of the mutual inductance and iron loss with the voltage/frequency ratio. A simulation model of induction motors considering the main flux saturation and iron loss is established, by the description of the main flux saturation and iron loss changing with the equivalent resistance curve of mutual inductance and iron loss fitted by polynomial. The steady and dynamic state results of the simulation and the experiment verify the correctness, validity and accuracy of the simulation model. It also provides a practical model, which is closer to the actual physical behavior of motors, to a high performance control of induction motors.
