    synchronous motor- exciter field rotation

    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 : )...

    synchronous motor- exciter field rotation

    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...

    synchronous motor- exciter field rotation

    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

    synchronous motor- exciter field rotation

    this motor has an ac rotating transformer / rectifier assembly to transmit dc to the rotor

    synchronous motor- exciter field rotation

    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...
