FIELD: electricity.
SUBSTANCE: syncronous generator includes stator magnet core made from laminated electrical steel having explicit poles where stator windings are situated, and rotor including rotor ferro-magnetic bushing where excitation poles are located. Besides according to the invention, ferro-magnetic shields are located at both sides of each pole. The said rotor bushing is manufactured with radial grooves being located under each excitation pole to ensure full excitation flowing through rotor poles and stator winding flows through the said shields and rotor bushing with maximum possible distance of stator flow in rotor bushing from excitation poles.
EFFECT: improved effectiveness of synchronous generators defined as ratio of available mechanical power produced by generator to mechanical power consumed by generator.
