Construction

Cooling System
Cooling System
IC 81W as per IEC60034-6. Primary fluid (water) is flowing by external water system. Internal air is flowing by a fan mounted on the shaft of the generator at the driven side.
Degree of protection
Degree of protection
IP 44 as per IEC60034-5. (Available up to IP 56)
Mounting
Mounting
IM B3 and V1 as per IEC60034-7.

Technical data

Stator/Rotor core
Stator/Rotor core
Laminated and enamel-insulated on both sides to minimise eddycurrent losses. The stator winding is made of flat copper or round copper wire depending on the machine size.
The completely wound stator pack is thereby impregnated in an epoxyresin VPI. The subsequent heat treatment hardens the resin.
Rotor
Rotor
Squirrel cage rotor type.
Depending on machine size, the rotor construction is either a solid shaft or welded ribbed shaft. The rotor winding can be either a pressure die cast aluminum or a copper bar construction.
Bearing
Bearing
General data
Antifriction bearings grease lubricated (ball or roller type) or oil lubricated sleeve bearing.
The theoretical lifetime of bearings, L10h according to ISO 281/1 standard, of standard horizontal construction generators, without external forces (radial and / or axial) is in excess of 50.000 hours. On request, the lifetime of bearings, L10h can be in excess of 100.000 hours.
Locating bearings are on the D end side and floating bearings on the ND end side.
Both bearings are fitted with a regreasing system.
The used grease is removed through a valve locked in the outer bearing cover. Sleeve bearings available as an option.
On request special bearings are designed where high radial and axial forces are applied. All configurations are designed to withstand the following marine inclination.
Static Dynamic
List 15° Rolling ±22.5°
Trim Pitch ±7.5°
Dedicated constructions available for different values.
Impregnation system
Impregnation system
Stator and rotor are VPI treated with an unsaturated polyester amide resin which is polymerisation in oven.
Insulation system
Insulation system
Low voltage
Stator: F class insulated with a synthetic enamel.
(H class insulation available on request)
Protective treatments
Protective treatments
Marine dedicated protective enamel is applied on the winding.
