Custom built for various turbine applications, durableElectric Machinery generators can be designedto meet individual arrangement requirements.

• Ratings range from 2,000 to 21,000kW (depending on speed) from 150 rpm for direct connected units and up to 900 rpm for higher speed gear driven units.

• Available in horizontal or vertical shaft configuration. Shaft extensions can be integral flange half coupling or cylindrical for shrink on coupling as required.

• Bearings arranged to handle radial and axial thrusts in both directions that are imposed on the generator.

• Rotor and bearings are designed to withstand runaway speed conditions specified by the turbine manufacturer.

Hydro Turbine Driven GeneratorsCustom designed to Customer Specification and TurbineManufacturer Requirements

WARRANTY

• Duraguard VPI (Vacuum Pressure Impregnation) insulation is fully Class F rated and uses a two part epoxy-mica system which resists chemicals and moisture, and provides long generator life. Global VPI of the complete winding is provided.

• Standard brushless excitation system provides high reliability and reduces maintenance and installation costs. The exciter is ventilated from the main generator and eliminates the need for separate ventilation paths. Alternatively, the generator can be provided with collector rings and brushes suitable for excitation from an outside source.

• Various generator enclosures are available, including drip proof guarded, WPII and TEWAC.

• Damper winding is continuous as standard, or can be furnished noncontinuous as required by customer specifications to provide smooth operation.

• Special electrical machine characteristics area available, including reactances, short circuit ratio, etc.

• Each generator is assembled and tested at rated speed and voltage in its own bearings.

Vertical synchronous generators with TEWAC enclosures

Custom built for various turbine applications, durable Converteam Electric Machinery generators can be designed to meet individual arrangement requirements.

StatorThe frame is welded and machined towithstand stresses exerted by electricaland mechanical forces in the core andprovide low vibration levels.

The stator is composed of a supportingstructure, a core of electrical laminationsand insulated windings.

The core is built up with high grade siliconsteel laminations that are precision punchedfrom core plated sheets. The laminationsare stacked in the support structure andspaced for radial ventilation to ensureeven cooling throughout the core. Thelaminations are pressed and held betweenend plates.

The windings are Vacuum PressureImpregnated (VPI) with a global processusing a two part epoxy resin. The VPI systemprovides excellent dielectric properties,superior resistance to moisture andchemicals, and outstanding mechanicalintegrity and long generator life.

RotorThe rotor consists of a spider on which thefield poles, amortisseur (damper) windingsand exciter armature are mounted.Depending primarily on the runaway speedrequirement, the rotor spider may befabricated steel with field pole anchorsusing high strength bolts, laminated sheetswith dovetails, or forged with tee ordovetail as required.

Industry standardsThe field poles are comprised of steellaminations that are pressed and boltedtogether to withstand rotational andelectrical stresses. Field pole windings canbe either rectangular wire or flat copperwound poles. Individual turns are thenbonded layer by layer to hold the windingsfirmly in position for normal and runawayspeed conditions.

Rotor insulation is a full Class F systemfor long, trouble-free performance.

Rotors are balanced at our factory toreduce vibration, provide smoothoperation, and meet the overspeedrequirements of the application.

Quality Assurance and TestingElectric Machinery is ISO-9001:2000 certified.

All generators are assembled and testedin their own bearings at normal operatingspeed and voltage. Routine tests areperformed as required per NEMA MG-1standard. Bearing temperatures andvibrations are monitored during testing.Additional tests include efficiency,temperature rise, operation at runaway/overspeed condition, etc. All testing isperformed in accordance with IEEEprocedures.
