This book is a compilation of knowledge about computer models in the three-phase stator reference frame. Chapters explore several aspects of the topic and build upon research previously presented by contributors. The book aims to provide interesting solutions to problems encountered in the design of railway and analysis in railway motors. The modeling approaches proposed by the authors in this book may become an incentive for readers and researchers to develop their 'lifehacks' to solve new problems in induction motor design and testing. Key topics presented in the book: - Approximate calculations of induction motor equivalent T-shaped circuit parameters with the use of catalogue data - Simulations of different types of shaft load, including fluid coupling - Receiving static characteristics of an electric machine during simulation by means of dynamic model - Simulation of the electric drive's specific applications with three-phase induction motors building - Direct start of an induction motor as part of an auxiliary drive of an AC electric locomotive, containing a capacitor phase splitter, starting with different types of shaft loads (fan or compressor). Special attention has been given to the description of the thermal model of an induction motor with a squirrel-cage rotor, which makes it possible to simulate operating modes when powered by an unbalanced voltage, as well as with squirrel cage defects. The thermal model is presented as a detailed superstructure to the model of electromechanical processes of an induction electric machine. Other key features of the book include references for further reading, an appendix for the parameters of the equivalent thermal circuit of an NVA-55 induction motor. The material presented in the book is of interest to railway motor engineers, specialists in electromechanics and electric drives who use SPICE-compatible CAD applications in their work
