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...
متن کاملMagnetic 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...
متن کاملModeling of synchronous machines with magnetic saturation
This paper deals with a method to derive multiple models of saturated round rotor synchronous machines, based on different selections of statespace variables. By considering the machine currents and fluxes as space vectors, possible d–q models are discussed and adequately numbered. As a result several novel models are found and presented. It is shown that the total number of d–q models for a sy...
متن کاملStator-Flux-Based Vector Control of Induction Machines in Magnetic Saturation
In many variable-torque applications of induction machines, it is desirable to operate the machine at high flux levels, thus allowing the machine to produce higher torques. This can lead to saturation of the main flux path, introducing crosscoupling effects which can severely disrupt the performance of controllers dependent on knowledge of the machine’s magnetic parameters. Stator-flux-oriented...
متن کاملInfluence 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 ...
