How are GE gas turbine rotors assembled?

At assembly, the GE gas turbine rotor construc-tion practice is to individually balance rotor components, (e.g. stub shafts, blade and wheel assemblies, distance pieces, and turbine wheels and spacers). These components are assembled into major subassemblies using a computer stacking program to minimize any runouts of the assembly.

What is the function of rotor blades in a wind turbine?

The rotor blades are key components of a wind turbine and are responsible for capturing the kinetic energy of the wind. The gearbox is used to increase the rotational speed of the blades and transmit the energy to the generator, which converts it into electrical energy.

What are the components of a rotor system?

1. Rotor system. This includes blades that capture energy and a rotor hub that connects the blades to the shaft, along with pitch mechanism that assists in efficient capture of energy. 3. Tower and foundation. These structural elements carry all the forces and moments to the ground 2. Nacelle.

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.).

How does a generator rotor work?

The rotor connects to the generator, either directly (if it's a direct drive turbine) or through a shaft and a series of gears (a gearbox) that speed up the rotation and allow for a physically smaller generator. This translation of aerodynamic force to rotation of a generator creates electricity.

What if a generator rotor has a negative sequence event?

However, if the generator rotor is subjected to significant negative sequence events, GE Energy Services should be consulted prior to the com-mencement of repairs or return to service. GE Energy Services can then determine the severi-ty of such an incident and advise in the inspec-tions that should be performed.
