CCS/TMS320F28069M: How to calculate the 5 parameter model parameters of induction motor?

Part Number: TMS320F28069M


Tool/software: Code Composer Studio

Hello!

I'm confused with the induction model parameters, please help with the following questions.

1, Is it possible to calculate all of the 5 parameter induction model's parameters using the results of FAST module?

2, How can I get the LM?

3,extern float_t EST_getLr_H(EST_Handle handle);

In the above function, does Lr = Lor + Lm?

Thanks a lot!

    It's not easy to get exact ACI model parameters from the 4 parameters identified by InstaSPIN-FOC. Please refer to Section 4.8 of InstaSPIN User's Guide (SPRUHJ1G), you might assume the Ls (Stator leakage inductance) equals to Lr (Stator referenced rotor leakage inductance) to calculate the similar model parameters.
