This paper deals with the parameter identification of an induction motor at standstill. A comprehensive identification procedure is analyzed, describing a robust flux-integration method for main-flux saturation characteristics and transient tests for rotor-side parameters. The influence of the main-flux saturation on the transient test results and on the identified rotorside parameters is studied, and improvements are suggested. The identification procedure is validated by means of experiments using 2.2-kW and 5.6-kW induction motors. Index Terms-Induction motor drives, parameter identification, saturation characteristics.

“…Because of the skin effect, the rotor bar parameters are functions of AC frequency [4,5], which lays a heavy burden on parameter computation. The parameter calculation is a trouble problem under a sinusoidal current conduction, what more difficult is to evaluate parameters with a nonsinusoidal current flowing through the rotor bar.…”

To evaluate the rotor bar parameters of an induction machine with the non-sinusoidal current, a new analysis approach, which employs the circuit analysis theory instead of electromagnetic field theory to count the skin effect, is proposed. In the presented method, a rotor bar is divided into many thin-layers with their own parameters derived. The superposition principle is proven for the calculation of total bar losses and slot magnetic energy due to the non-sinusoidal current composed of sinusoidal components with different frequencies, which shows the parameters of the bar can be expressed with the parameters at respective frequencies.For given examples, the parameters at different frequencies are calculated, and the results are verified by the analytical method or the finite element method.

This paper deals with modeling of a saturated induction machine. In control algorithms, the inverse-Γ model is widely used. However, the saturation models are typically based on the T or Γ model. Transformation between these models is easy if the machine is magnetically linear, but since the motor saturates, the modeling becomes more complex. In this paper, we study the properties of the Γ and inverse-Γ models and the transformation between these two models when the saturation is taken into account. The phenomena related to model transformation are studied by means of analytical equations. Also, the functionality of the models is studied by means of laboratory experiments.
