Again thanks for your help, yes the rectifier bridge its disconnected, actually i did it without having installed the stator and rotor of the exciter.
When i do the jumpers between a1-2 and a2-1 the induce voltage must be in the rotor wires as well as i did on the coil i.d? Apply the same...
Hi Waross how are you?,
i did the following: with the Variac i sent 120 Vac directly to the rotor, then i took the voltmeter and took a random coil and marked it as A11 and A12 and turn the rotor until i got the max. voltaje (1.3 Vac), and stop there i identify 5 more of coils and then rotate...
Thanks a lot, you have been very helpful.
Ok i will start identifying the group coils and once i finish ill let you know so i can continue with identifying the polarity.
Muchas gracias!.
Thanks for your prompt answell Waross,
yes its a 1000 kW three phase Ac generator. its brushless it has PMG excitation.
The insulation its ok, it was cut off maybe they stole the wires for selling cooper.
Few Ac amps, will be with 110 AC or less voltage ? i have a variac. the AC voltage should...
Hi how are you all?, ill appreciate if you can help me, i have a kato Ac generator that the leads were cutoff and i dont have any identification. Dont know if there is a method for identifying wich group of leads makes each phase.
The generator stator is a 6 parallel group with 6 leads per...
