ROTATING ELECTRICAL MACHINE Russian patent published in 2015 - IPC H02K3/51 

FIELD: electricity.

SUBSTANCE: invention is related to rotating electrical machine (10), in particular to a hydrogenerator (11), which comprises the rotor multilayer unit (12) passing in direction of the machine axis (20) and having the rotor winding that forms the front winding at each butt-end of the rotor multilayer unit (12), at that the front winding is fixed to the front winding rim (13), which is placed concentrically inside the front winding and connected to the rotor multilayer unit (12) in axial direction in order to compensate centrifugal forces by means of bolts (18) passing radially through the front winding and a fixture (16, 17, 18) intended for reliable compensation of axial expansion in the front winding. The bolts (18) are fixed to the front winding rim (13) in each case by an element (17) with T-shaped cross-section, which passes in axial direction and is installed to move axially in a matching T-shaped axial cut made in the rim (13) of the front winding.

EFFECT: providing reliability of the fixture.
