HI,
We ran the induction motor in a closed loop. We can’t control RPM below 60 RPM.electrical angle going haywire in below 60 RPM.i adjust gains also. Is there any other method for controlling induction motor in Low RPM. is there Voltage feedback(U-V-W) required for smooth control on low RPM. Awaiting our valuable suggestion.
Thanks,
BIPIN PATIL.
