How to remove the fan blades of a 5kw generator

How do you remove a rotor?

Cut 2.5 inches from the hex head end of the rotor (Figure 5-11, Item 15) bolt. Remove the exhaust clamp. (Figure 5-11, Item 35) Slot the end of the bolt to suit a flat blade screwdriver. Page 73 Section 5 Disassembly 004674 Figure 5-9. Remove Rotor 004675 Figure 5-10.

How does a generator revolving rotor work?

Description and Components Section 1 Introduction Engine-Generator Drive System The generator revolving field (rotor) is driven by an air- Figure 1-1. The generator revolving field is driven by cooled engine at 3600 rpm. air-cooled, horizontal crankshaft engine. The generator is directly coupled to the engine crankshaft.

How does a generator revolving field work?

The generator revolving field is driven by cooled engine at 3600 rpm. air-cooled, horizontal crankshaft engine. The generator is directly coupled to the engine crankshaft. The generator may be used to supply electrical power for Both the engine and generator rotor are driven at the operation of 120 and, or 240 volts, single-phase, 60...

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?

Can a generator rotor Rewind increase MVAR and mw?

An uprate often can be realized while perform-ing a rewind, modification or replacement to a generator rotor. For example, a rewind could be an opportunity to install new Class F tem-perature-insulating materials. Running at a higher temperature from higher field amps can produce more flux and more MVAR and/or MW.

How do generator rotors get contaminated?

Contamination of generator rotors can come from many sources. Carbon, which represents one of the more common contaminates, can come from collector brush wear or gas turbine exhaust. Other particulates likely to be found in a generator (such as silicon or petroleum by-products) can come from nearby operations or processes.
