STATOR OF ELECTRICAL MACHINES Russian patent published in 2006 - IPC H02K1/16 

FIELD: electrical engineering, in particular, high-power turbogenerators.

SUBSTANCE: the stator of the electrical machine has a core with terminal laminations, whose end-face area consists of a tapered and flat circular surfaces, is tightened by means of studs through non-magnetic pins resting on the tapered surface of the lamination, according to the given invention, installed between the flat circular surface of the terminal lamination and the non-magnetic rings, whose radial dimension does not extend from the inside diameter of the body wall, is a pressing ring with an outside diameter less than the inside diameter of the stator body wall conjugated to the non-magnetic pins through spacers of insulation material with the aid of a boss entering the respective recess on the non-magnetic pins.

EFFECT: enhanced operating reliability of the electrical machine due to provision of movement of the core heated in the process of its operation to both sides because of the absence of fastening of the ends of the non-magnetic pins to the stator body walls, and provision of tightening of the terminal lamination to the core both on the tapered and flat surfaces of the terminal lamination.
