that's roundabout the conclusion that i rationalized. the lower supplied excitaion voltage means the transformer is more being more effective; same rpms, same power factor, assumed same dc rotor voltage... it would have been nice if the manual laid that out, but that's a different post : )...
That's correct and basicaly what the manufacture states in the manual; don't use the wrong one... but i have no idea how to tell what the right one is. both configurations run stably. i'm about to get the power quality meter out and see if there is a diference in power factor, but i feel the...
i'm talking about the ac rotation supplied to the rotating transformer. i've been advised that the ac field should be in direct opposition to the mechanical rotation, but i have nothing but my test results and the feel a bit inconclusive
I have a question about the effects of changing the roation of the ac exciter field on a synchronous motor and how to tell which way is right, or if it matters at all...
i could post the nameplate stats, but i feel my test results are more relevant.
with the motor at 100% (360rpm) i have an...
