Thanks for all your help and info.
While Motors have never really been my strong suit, I wish to learn all that I can about this subject and I am getting better at working with them.
My Trade Cert exam was a nightmare, as most of the questions pertained to motors or transformers or power factor correction, all the Inductive things.
Experience in the field though has taught me to work calc's pertaining to this sort of thing out, either on paper or in my head.
I was taught at school before the advent of the pocket calculator, I think that was a life-saver to be honest!.
