Rotors and high-speed electric machines
WELMA200 electric generator
Electric generator is designed for integration into a gas turbine power plant. This product provides the generation of electric energy which is further converted into a given type and quality in the power plant systems. The generator is a synchronous reversible electric machine with excitation from high-coercitivity permanent magnets.
The rotor of the product is mounted on two radial ball bearings. Cooling and lubrication of bearing supports is carried out by oil supply from the oil system of the gas turbine plant.
