Product catalog summary
Introduction
BRUSH DAX cylindrical rotor, air-cooled generators are widely used in various applications including public utility, cogeneration, CHP, industrial, and offshore. They are compatible with both steam and gas turbines, with BRUSH having extensive experience in gas turbine applications.

Stator
The stator frame is made from mild steel and designed to handle mechanical stresses. It features a core of high silicon content electrical steel, with radial ventilation ducts. The stator winding uses a two-layer diamond type with high-performance insulation capable of operating at temperatures up to 155°C.

Rotor
The rotor is crafted from nickel chromium molybdenum alloy steel, featuring axial slots for windings and ventilation. The rotor winding uses high conductivity copper/silver alloy, with a class ‘F’ insulation system that is moisture resistant and shockproof.

Bearings
Main bearings are typically fixed profile, white metal lined, hydrodynamic bearings, with options for other profiles like tilting pad bearings.

Cooling
BRUSH DAX turbogenerators use air cooling, either in open or closed circuit configurations. Cooling circuits are designed for uniform cooling of windings.

Excitation System
Most BRUSH DAX generators use brushless excitation systems, featuring a rotating armature and stationary field winding. A static excitation system is also available.

International Sales and Support
BRUSH provides international sales and support with locations in the USA, UAE, UK, and Malaysia.

Features and Specifications
BRUSH DAX generators offer simple foundation design, modular construction, and compliance with international standards like IEC and IEEE. They support a voltage range up to 20kV, speeds of 3000 rev/min for 50Hz and 3600 rev/min for 60Hz, and an output range of 10 to 250MVA.

DAX 2 pole turbogenerator-3

The rotor of a BRUSH DAX turbogenerator is manufactured from a one-piece forging of nickel chromium molybdenum alloy steel which is de-gassed and vacuum poured to obtain a uniform material which has excellent tensile properties. BRUSH DAX turbogenerators are cooled by air, either in open circuit or closed air circuit configuration. The generator internal system is similar in all cases. Axial slots, to carry the windings and for ventilation, are milled on the periphery of the body of the rotor. The rotor winding conductor material is high conductivity copper/silver alloy strip. The pre-formed...
