Such work can involve blade-tip and angel-wing restoration, DSD correc-tion, restoration of blade clearances (shroud blocks and blade tip heights), and/or application of an anti-rock coating.

Since a generator requires mechanical energy to produce electricity, the rotor plays the most crucial part by generating an electric field between it and the stator, a set of electrical conductors in coils. 2. Find the
the fans that are set up on the Retainin g Ring, is blown in two sides of rotor. Fig. 1. Generator diagram At each of two sides of generator sets up 11 blades as an axial fan that separates
AC impedance test. The AC impedance test is used to find indications of shorted rotor turns. The test is performed by means of applying an AC voltage across the field winding and raising it in 10-volt steps up to 100-120 volts, or till the
This guide demonstrates how to remove or replace the rotor and stator assembly on your Honda EB3000CK2A 3000 Watt Generator. The rotor and stator are removed as one unit. If you need to replace the rotor or stator individually,
This degrada-tion can lead to shorted turns, a field ground, or an in-service operational incident that can require premature maintenance work. The type of work needed to repair and upgrade depends upon the generator rotor design, length of time in service and the manner in which the rotor was operated.
Disconnect the generator field (rotor) leads from the positive (+) and negative (-) exciter armature lead terminals located on the rotating rectifier assembly. Using a hoist and strap, slide out and remove the exciter armature and rectifier tube assembly, which is keyed onto the shaft. Connect a hoist to the lifting eyes.
As the generator rotor rotates a voltage will be induced and current will flow in the alternator stator windings and to the output circuit. All connections between the exciter stator windings and the generator stator windings are internally connected within the stator housing.
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.

A fully equipped the generator necessary to gain access to the rotor. GE recommends a high speed balance whenever the rotor is rewound with new coils. However,
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.
