ROTOR FOR ELECTRODYNAMIC MACHINE Russian patent published in 2013 - IPC H02K1/32 H02K1/26 H02K9/12 

FIELD: electricity.

SUBSTANCE: rotor for an electrodynamic machine, in particular, for a hydraulic generator, comprises a body, which is assembled from many segments (10) of sheet metal arranged in axial direction one after another, between segments (10) for creation of cooling channels there are location links (14), which are supported by bolts (12) to carry centrifugal forces acting on them, and the bolts stretch in axial direction through the body of the rotor of sheet metal. At the same time at least one part of the specified location links is assembled from many separate parts at least partially located above each other. Each assembled location link comprises an upper part and a lower part, at the same time one of both specified parts has an expanded first section with a hole for insertion of axial bolts of the body from sheet metal, and also two narrow second sections in the form of radial fingers, which are arranged at the distance from each other, and another one from both specified parts is made in the form of a disc with a hole, at the same time the specified disc with a hole and the specified first section with the hole arranged in it are arranged above each other.

EFFECT: provision of simple facilities of protection for specified location links against hazardous impact of centrifugal forces in process of electric machine operation.
