Has anyone ever seen anything like this winding configuration?
We have no name plate information but the client says it is a GM Hybrid motor/3 phase. He doesn't know the rpm rating.
My dilemna is where to get/ make coils to rewind this...
We have had a EM 2200kva 6 pole turbine driven generator in our shop for repair with which we are having a problem.
The unit came in for repair with a low ground reading on the wound rotor (.3 meg ohms). We cleaned and varnish treated the rotor and got it to come up to 4200 MOhms. We assembled...
Has anyone ever heard of using a "AC curve test" to set neutral on a DC machine. We have a client who has requested this procedure to set the neutral on (2) 1500 HP DC main propulsion motors that power a research vessel. They have been experiencing sparking on the commutator at full load on the...
We recently recieved a 3 speed 2 winding marine winch motor for rewind in our shop. The motor had been recently rewound at a shop in Russia. The rewound motor never worked properly and actually failed shortly after installation according to the ship's engineer. I have tried to get winding data...
We rewound the stator on a KATO 270 KW/300 KVA 460v 625amp 100HZ single phase 10 pole synchronous generator that is driven by a six pole 60HZ synchronous motor. The generator puts out the correct voltage and frequency and for all purposes, it functions as it should. The problem is that it now...
We recently rewound a 100HZ single phase 10 pole synchronous generator that is driven by a six pole 60HZ synchronous motor. The generator puts out the correct voltage and frequency and for all purposes, it functions as it should. The problem is that it now emits a high pitched whine that...
