FIELD: machine building.
SUBSTANCE: invention can be used in production of inductor synchronous generators. Objective is achieved by reducing value of bearing currents. Inductor synchronous generator consists of housing, stator pack, toothed rotor packet bearing shields, bearings, labyrinths mating parts of labyrinths, shaft, key slot on shaft. Labyrinths, pressing outer races, and in their mating parts fitted on shaft is carried out at three or more flat ribs and projections, identical in shape and size. Ribs of labyrinths are with clearance in space between projections of their mating parts, and projections of latter between ribs of labyrinths.
EFFECT: higher reliability, durability and manufacturability of generators.
