Rotors and high-speed electric machines
WELMA 10 electric generator
Electric generator is designed to work as part of the test stand. The generator is mounted on gearbox casing and connected to load unit of the stand and provides load of assembly under test according to the set program. Generator is a synchronous electric machine with excitation from high-coercivity permanent magnets.
Generator is cooled by air. Rotor supports are radial ball bearings. Bearing supports are cooled and lubricated with oil supplied from the oil system of the stand.
