Fast and Accurate Modeling of Squirrel Cage Induction Machines for the Transient Electro-mechanical Simulation of Electrified Drivetrains

This paper presents a transient reduced-order model of squirrel cage induction machines for multiphysics simulation environments. By solving a differential-algebraic system of equations parametrized by magnetostatic finite element calculations, the model enables both fast and accurate results for system simulations. Therefore, the model is applicable to the electro-mechanical analysis of electrified drivetrains in the whole operation range. Properties and simplifications of this model are discussed. The impact of the simplification of sinusoidally distributed rotor currents is reported with a numerical example.
