CONFIGURATION AND SCOPE OF SUPPLY

GENERAL                                                                                                

The generator is designed to operate together with a diesel engine

CONSTRUCTION                                                                                      

The stator frame is a rigid welded steel structure construction. The stator core is built of thin electric
sheet steel laminations which are insulated on both sides with heat-resistant inorganic resin. The radial
cooling ducts in the stator core insure uniform and effective cooling of the stator.
The rotor consists of a shaft poles fixed on the shaft, exciter and a fan(s). The shaft is machined of steel
forging. The poles are manufactured of 2 mm sheet steel and bolted from the top to the shaft. The pole
laminations are pressed together with steel bars, which are welded to the end plates. The exciter rotor
and the fan are shrink fitted onto the shaft and secured with a key.
All windings are completely vacuum pressure impregnated with high quality epoxy resin. The windings
are provided with very strong bracing which withstands all expected mechanical and electrical shocks
and vibrations as well as chemicals. For more information ask for brochure "MICADUR-Compact
Industry Insulation System"
The stator frame, core support and end shields are made of fabricated steel and welded together. The
stator frame is closed with steel panels that guide the ventilation air and provide the degree of protection
required. The flange mounted bearings are bolted to the end shields
According to IM1101 the machine has 2 bearings. The feet are raised. The Shaft end is cylindrical

FOUNDATION                                                                                                     

The generator can be mounted rigidly on a common base frame designed by the engine manufacturer,
together with the engine type mentioned in this specification. Maximum allowed vibrations in the
bearings and feet of the coupled generator are according to ISO 8528-9, according to value 2. The
machine can be mounted using shimming, machined blocks, chock fast or vibration elements as long as
relevant mounting instructions and the requirements of the classification society are followed.

COOLING                                                                                                              

Brushless excitation. The excitation requires the following components: Current transformers for booster
excitation and actual value measurement. 3-core voltage transformer for measurement and excitation
power supply.
