SYNCHRONOUS GENERATOR Russian patent published in 2013 - IPC H02K19/16 H02K19/20 H02K1/32 H02K9/04 

FIELD: electricity.

SUBSTANCE: in a synchronous generator, comprising stator, front and rear covers, a rotor with beaked pole tips and an excitation coil, according to this invention, the rotor is additionally equipped with a star-like non-magnetic link with a central hole. The latter is installed in the middle of the coil in the plane of its rotation, and link teeth are arranged between beaked tips. Using this invention makes it possible to efficiently use ventilation action of pole tips, at the same time each of tip sets cools the appropriate front part of the stator. At the same time, if separate fans are used, the number of vanes in their blades may be excluded or anyway reduced, and the vane width may be decreased. These effects are achieved by using a technologically simple part of a star-like non-magnetic link, which may be made, for instance, by means of casting from plastic.

EFFECT: improved operational characteristics due to reduced consumed power spent for ventilation and improvement of thermal characteristics.
