Hi @xiangjun_rong ,
So I downloaded the software package and in it, there is an excel file called "Parameter calculation".
do you have documentation on how the flux observer Flux Observer's Flux_Max, Rotor_Flux, and Current_limit are obtained? Is the current limit the nominal current of the motor? I have added a screenshot below;
thanks in advance.
Hi, Kabenla,
These are motor itself parameters, I think the motor manufacturer can provide them, we have not documentation for them.

Hi @xiangjun_rong ,
Thanks for your feedback.
I was also wondering how the shift values shown in the screenshot below are obtained
I have tried to adapt the parameter to a large size motor but can't seem to get the motor to spin. On analysis, I realized that the estimated position from the flux observer is constant. This is why I am trying to figure out more about how these parameters are obtained and how to scale them a different motor.
