4 Frequently Asked Questions about "Generator rotor wind holes"

What is a generator rotor?

The generator rotor represents an excellent combination of electrical, mechanical and man- ufacturing skills in which the field coils are well insulated, supported and ventilated in a com- pound structure rotating at very high speed (typically 1800 or 3600 rpm).

Can a generator rotor be converted to a direct cooled winding?

Depending on the design of the rotor, in some cases it is possible to convert to a direct-cooled winding. Converting involves machining subslots in the rotor forging below the coil slots. Because of rotor geometry and size, this modifica- tion is not possible on all rotors. Q. Is there asbestos in generator rotor insulation and blocking materials?

Why do generator rotors have aluminum windings?

Aluminum alloy (condal) windings were incorporated on some generator rotors, enabling the rotor size and ratings to increase and still allow conventional indirect cooling to be used in the design of these units. These units have provided many years of reliable operation.

What causes a generator rotor to degrade?

One component of the generator that is typically refurbished, upgraded or uprated is the generator rotor (field). Degradation of the generator field can be caused by a number of factors, including a breakdown in insulation due to time and tem- perature and mechanical wear.
