Original poster: "Mike" <induction@xxxxxxxxxxx> Hi Carl,
Snip
Next week or two, if I can cut loose from other stuff at work, I will try and use the LRC meter to get you some L values on the AC windings as well as the control windings.Mike
Mike,Pls. notice that few LCR meters can supply enough current to produce a usefull measurement on iron cored inductors. By exciting the windings with a typical LCR meter, the iron will be operating in the low "initial permeability" area of the B-H curve, and the readings will turn out to be too small.
Instead, you should connect the windings across a variac, with a Ammeter in series, and calculate inductance according to:
u = wLi W = Omega = 2*pi*frequency = 2 * 3.14 * 60 = 377 Cheers, Finn Hammer
