Induction motors can be represented by the 2-axis theory, by using the derivations for synchronous machines but deleting the field winding. In this case some of the reactances become zero, and the field resistance is infinity. Hence, the derived reactances X ... 

A summarised description of the generalised theory of electrical machines is given, with an emphasis on synchronous generators and induction motors. Many texts are available that provide detailed mathematical treatments of the subject, for example References 1 to 6. Some texts develop the theory from a more practical perspective snch as References 7 to 12. 

In the sequel, some general issues concerning AC-machines modeling, mainly change of variables through coordinate transformation (reference-frame theory, see [8]) are discussed. This is followed by the presentation of machine schematics in machine variables and equivalent circuits in transformed variables of both the synchronous and the induction machines, under detailed modeling assumptions. This is accompanied by the corresponding BG models of both machines in transformed variables. Finally, simplified models of the induction motor usually encountered in control system applications are addressed.
