Rigid frame, rugged welded steel fabrication (EN 10025 - S235 JR). Frame is provided with side ribs to increase the strength.Marelli Motori motors for continuous duty operation are designed to meet vibration levels per IEC 60034-14, ISO 10816-1 and BS 5000-3.

Made of grey cast-iron (EN 1561 – GJL 200) up to 500 frame size motors. Made of hot-rolled structural steel (EN 10025 – S235 JR) from size 560 and above.

General dataMade in carbon steel (EN 10083 – 2 C40 – TN) up to 450 frame and hot-rolled struc-tural steel from 500 frame (EN 10025 – S355 JR).

Shaft designCylindrical shaft with key.

Mounted on side (right or left to be selected). Made of formable steels EN 10130.

Made of aluminum alloy up to 400 frame.Made of hot-rolled structural steel above (EN 10025 – S235 JR).

Construction• mounted on top of the machine • double tube made of CuNi 90/10• copper �ns housing• equipped with water leakage detector • certi�ed by registers of shipping in compliance with Rules for Classi�cation of

Ship• coolant can be both fresh or sea water• suitable to be treated with corrosion inhibitors, PH regulators and anti freeze as

appropriate to site conditions.

Exchanger data• designed pressure 6 bar• test pressure 10 bar• max glycol: 30%• type of water: fresh water or marine (salt) water• �anges: PN6 – PN10 – Special (ANSI).

TEWAC – Totally Enclosed Water to Air Cooled

IC 81W as per IEC60034-6. Primary �uid (water) is �owing by external water system. Internal air is �owing by a fan mounted on the shaft of the generator at the driven side.

IP 44 as per IEC60034-5. (Available up to IP 56)

IM B3, V1 and V10 as per IEC60034-7.

Laminated and enamel-insulated on both sides to minimise eddy-current losses. The stator winding is made of �at copper or round copper wire depending on the machine size.The completely wound stator pack is thereby impregnated in an epoxy-resin VPI. The subsequent heat treatment hardens the resin.

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 con-struction.

General dataAntifriction bearings grease lubricated (ball or roller type) or oil lubricated sleeve be-aring.The theoretical lifetime of bearings, L10h according to ISO 281/1 standard, of stan-dard 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 �oating bearings on the ND end side.Both bearings are �tted 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 ap-plied. All con�gurations are designed to withstand the following marine inclination

Dedicated constructions available for different values.

Stator and rotor are VPI treated with an unsaturated polyester amide resin which is polymerisation in oven.

Low voltageStator: F class insulated with a synthetic enamel. (H class insulation available on request)

Marine dedicated protective enamel is applied on the winding.

• Dual/multiple winding con�guration • �anged shaft or special shaft end on both sides• increase protection degree up to IP 56• encoder• vibration sensors• special frame design to suite the application• special bearings (sleeve or angular contact bearings)• reinforced winding for VFD operation• insulated bearings design for VFD application• shaft earth brush for VFD application• other options available on request.
