Modelling of induction motor incorporating magnetic saturation

Influence of Magnetic Saturation on Induction Motor Model Selection

Effects of magnetic saturation on various equivalent circuit models of an induction motor are studied. The parameters of 2.2-kW and 37-kW motors with closed rotor slots are analyzed using finite element computations. Both skewed and unskewed rotor slots are studied. The magnetizing inductance not only depends on the main flux, but is also dependent on the rotor current, especially if the rotor ...

Accounting for magnetic saturation in induction machines modelling

A new model is developed for (uniform air-gap) induction motor that accounts for the saturation feature of the machine magnetic circuit. It is built-up starting from the basic electrical/mechanical laws and turns out to be quite different from the standard model that is widely used in control oriented literature. Specifically, the new model involves state-dependent parameters. An experimental v...

Magnetic Saturation Impacts on Fault Analysis of Squirrel-Cage Induction Motors using Winding Function Approach

Multiple coupled circuit modeling of squirrel-cage induction motors, or winding function approach is the most detailed and complete analytical model used to analyze the performance of the faulty induction motors. This paper extends the above-mentioned model to a saturable model including variable degrees of the saturation effects using an appropriate air gap function and novel techniques for lo...

High-performance motion control of an induction motor with magnetic saturation

This work generalizes the authors’ work on highperformance control of induction motors to machines that exhibit significant magnetic saturation. The controller design is based on the standard d–q model of the induction motor which has been modified to account for the saturation of the iron in the main (magnetic) path of the machine. An input–output linearization controller is used to provide in...
