Induction Machine Stator-Rotor turns ratio

Dear Mathworks Support,

How to set stator-rotor turns ratio of an induction motor (wound rotor)?

I understand you are referring to this Asynchronous machine:

If so, the stator-rotor turn ratio is captured in the resistance and inductance of the Stator and Rotor.

They should follow the following equation:

Rr' = a^2 * Rs; Llr' = a^2 * Lls;

hence, mention your resistance and inductance accordingly.

Thanks, Sandip, MathWorks

In Matlab simulink usely Llr' = Lls, that's mean a = 1 ? But Rr' no equal Rs Thanks and best regard
