The Dynamic Model and Block Diagram of a Linear Asynchronous Motor

摘要

A step-by step procedure of constructing the mathematical model of a linear asynchronous motor based on the structural modeling method is outlined. The interrelated electrical, magnetic and mechanical parts of the machine are represented in the dynamic and harmonized manner. The magnetic circuit with a complicated configuration of the boundaries is represented in the form of equivalent circuit detailed to the level of tooth loops. The electromagnetic and electromechanical processes in the linear motor are described by ordinary differential equations. Ways of taking into account the tooth nature of the air gap zone and saturation of the parts of the magnetic circuit are shown. The model is realized in the Matlab-Simulink computer program.
