ACIM motor parameters

Motor_Enthusiast

I am working with instaspin for driving an acim motor. I am trying to identify the motor parameters.

Is the rotor resistance value Rr written in user.h file referred to stator or not? I mean is it directly Rr = R2 or Rr = R2/s?

Best regards.

    The rotor resistance in user.h needs to be a scaled resistance, which includes other parameters. From a standard ACIM datasheet, you can calculate the rotor resistance used by InstaSPIN by following a procedure we have in the user's guide. Please refer to section:

    4.8 Setting ACIM Motor Parameters in user.h
