Hi all,
I have a question in interpreting a X/R ratio for motors on the IEEE Std 141-1993, Figure 4A-3. The figure has two bands, and it is divided in three catagories(High,Medium, and Low Voltage). If I have a low voltage motor, does it mean the X/R ratio of the motor can be range between 1 to 6? Nowaday, we have these very high efficiency motor. Does this IEEE table still apply to these high efficiency motors?
Thank you for helping out.
