ELECTRIC MACHINE, IN PARTICULAR, THREE-PHASE ASYNCHRONOUS HYDROGENERATOR Russian patent published in 2013 - IPC H02K3/12 H02K3/28 H02K3/50 

FIELD: electricity.

SUBSTANCE: invention relates to design of electric machines, in particular, a three-phase asynchronous hydrogenerator with a rotor and a stator, and also with a winding comprising multiple winding rods (17, 18) stretching in axial direction, lying above each other in appropriate slots of the yoke winding, besides, winding rods (17, 18) protrude from the winding slots at the ends of the machine and in the front part (13 a, b) of the winding according to the specified circuit are multiply pairwise electrically connected to each other, besides, the upper rod (18) of the winding of the first winding slot and accordingly the second rod (17) of the second winding slot is therefore bent to each other, so that their ends (21, 22) in axial direction cross above each other, and the connection (16) of the winding rods (17, 18) of the electrically connected pair of winding rods is carried out with the help of a solid connection element (27). At the same time, according to this invention, the ends of electrically connected to each other winding rods (17, 18) the windings are made as straight tabs (21, 22) of rectangular section, and the connection element is made as a round eyelet (27) aligned in the radial direction, having two radially crossing above each other support surfaces (28, 29) for arrangement of on the tabs (21, 22) of the winding rods (17, 18) connected with each other.

EFFECT: provision of higher mechanical stability of a structure and simultaneously simpler assembly, minimisation of transition resistances, with preservation of a front part of a winding shortened in axial direction.
