Dear Community,
For our motor control application we are using a TI F28062 processor running Instaspin FOC.
We have an interesting observation, our Rs Online has a dip of about 25% when motor RPM drops below 300 RPM. This is not observed at speeds well above 300 RPM. Its interesting to know if the community has observed the same, since the code is proprietary we cannot study this behavior.
Another observation is the Rs estimated during motor Identification, differs significantly from the Rs when we do Rs recalc. In other words, the initial result of Rs recalc differs much from the Rs estimated during motor identification.
Please advice,
Regards
