HIGH-SPEED GENERATOR Russian patent published in 2019 - IPC H02K9/16 H02K1/32 

FIELD: electrical equipment.

SUBSTANCE: invention relates to the electrical equipment. In high-speed generator rotor is made in the form of annular permanent magnet fixed on shaft, axial movement of which is prevented by thrust-sealing and thrust rings. Rings are located between front and rear covers arranged on housing with stator and in which supply union is installed. Oil is injected via the nozzle into the generator inner cavity at pressure of 2–5 kg/cm², leakage of which prevents thrust-sealing ring providing rotation of rotor with high speed, as sliding bearing. Through drain unions arranged in side covers, oil is drained, removing heat from stator winding and generator rotor.

EFFECT: higher reliability of the generator, higher operating frequency of rotation and improved heat removal from the generator.
