Yes i understand this... and i think that is what is happening here, up to a point... because things are behaving strange


lets say 10 hz


my field coil has 3 ohms also and 22mh


so at ten hertz the reactance impedance should be 1,4 ohms



so the impedance should be around 4 ohms this should make at least 3 amps flow having 13v, but i'm getting 260ma ..


Is very strange for me... Seems like the armature add a kind of extra impedance to the change of the current direction-- but i'm not sure if this is the case.. .will keep experimenting,


i'm going to try adding a capacitor in parallel or a diode to the field coil and check what happens!


Oh and the most stranger behavior is that at a frequency higher than 10khz the amps start to get higher... at 100khz i get 1,20 amps...


I don't know if is the meter witch is crap... i'm going to try with the other meter witch can measure dc or ac current...


Thanks Donald
