Beginning with a brief review of current balance standards, for both rigid and flexible rotors, and ending with specific case histories and actual solutions, this paper should be useful to
This document discusses generator rotor design, operational issues, and refurbishment options. It describes the function of generator rotors in producing an electromagnetic field for electricity generation.
In this paper, when FBO occurs, the load characteristics of the rotor system are described with the low-pressure rotor structure of a high bypass ratio turbofan engine.
Abstract and Figures Since the optimum operation of a generator is highly affected by increasing in temperature, a cooling system is used to control the temperature.
In large machines, balance weights, bolts, nuts, and any other rotor attachments are subjected to intensive centrifugal forces. The chapter provides discussion about the condition of the windings,
It this paper, a mechanical analysis was performed with the metallurgical examinations for competent analysis of blade failure. The mechanical analysis capable of predicating stress and
In gas turbine power plants, a fan is used as a cooling system to dissipate generated heat in coils (copper conductors) and generator electric circuits at the end sides of
Short Summary: This entry discusses rotor windings, including damper windings and fan blades in hydro units. It covers their importance, common issues, and their impact on generator performance.
The potential failure of generator rotor fan vanes and blower blades has been identified as an area for detailed risk assessment in the electric power generation industry.
Visual inspections were taken on the generator parts especially on the fan blades and the effect of accident on them was studied. Three kinds of blades were found in the turbine casing after the
