Discharge resistor for synchronous motor

Discharge resistor for synchronous motor

Discharge resistor for synchronous motor

(OP)
We have a synchronous motor 3250 kW with brushless exciter with rotating diodes. The power resistor ~4 ohmi from rotating part must be replaced. I don't know the manufacturer. Anybody know a manufacturer of such power resistors fitted on the rotating part?

RE: Discharge resistor for synchronous motor

You better approach the motor manufacturer.
Normally, these resistors are custom made in the works of motor manufacturer or in the works of their sub-supplier (complying to the specs of the motor manufacturer).

RE: Discharge resistor for synchronous motor

By power resistor, do you mean the surge arrester in the rotating rectifier assembly? If yes, its resistance is much more than 4 ohms. And the OEM might the only source for a new arrester.

RE: Discharge resistor for synchronous motor

There could be manufacturers that could do it but not have it listed as a product line since it's an OEM part. You could also take the old one (or enough dimensions of it) to some power resistor manufacturers and see if one can make a duplicate.
