WebJan 12, 2010 · If we use FLA as a starting point, then magnetizing current is FLA*sqrt (1-PF^2), which is 233*.535 = 125 A. Then, a 480 V grid usually means a 460 V motor. That could change things, but not much (a few percents). Your 90 A no load seems OK, a little low, but not to worry about. As Bill says; checked your meters lately?
