4.1 STANDARD MOTOR MODEL
In order to aid in explaining the results from the experimental data and to extend the study
conditions not easily tested in the laboratory, a model of the system constructed in the
laboratory is needed. A good starting point is the standard dq0 reference frame induction
motor model introduced in the prior work section.
The familiar equations of the standard induction motor model represented in the dq0
stationary reference frame are as follows [37][38]. A more in depth treatment is covered in
Appendix A.
The stator voltages are:
