Generator rotor air inlet and outlet

How does a generator rotor and stator work?

The generator rotor and stator incorporated inlet and outlet sections along their axial lengths to achieve uniform cooling along the length of the generator field. This uniform cooling elim-inated axial hotspots and allowed the ratings of the generators to be increased.

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).

What are the components of a generator rotor?

the size and life of generator rotors are temperature, mechanical force and electrical insulation. typical generator field. Note the major components: rework or modifications is also discussed. This There are, of course, variations on this configuration. For example, while the illustrated design uses radial fans, other designs use axial fans.

How to choose a generator rotor?

The first step in considering a generator rotor most labor intensive (hand taped) since the turn rewind is to define its intended use. For exam- adds to the coil width. (See Figure 16.) power etc.).

Do axially ventilated generators have a salient pole rotor?

The flow field attributes of an axially ventilated generator model with a salient pole rotor are investigated both experimentally and numerically. Mean total pressure and instantaneous velocity distributions are measured at the outlet of the stator ventilation channels.

Why do Gen-erator rotors have aluminum windings?

Aluminum alloy (con-dal) windings were incorporated on some gen-erator rotors, enabling the rotor size and rat-ings 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.
