Sorry, sloppy terminology from a workshop floor. By this I mean we have two leads, F1 and F2. Test 1 is conducted F1 Active F2 Neutral, test 2 conducted F1 Neutral F2 Active. AC doesn't have polarity per se which is why I am confused as to why swapping the leads would make a difference but...
Thanks! It is a DC motor, shunt field circuit connected in series with each other. No armature present at time of test. I should clarify that I am aware of other suitable tests and indeed there is no polarity issue with the unit, I just can not figure out how this test works in regards to the...
I work in a large electrical machine shop. We have a test that no one can explain to me. We energise a dc field frame (in this case 6 pole) with ac and record the current draw, then reverse the polarity of connection, energise and compare values. If a pole is reversed polarity then a difference...
