ROTATING ELECTRICAL MACHINE, NAMELY ASYNCHRONOUS MACHINE OF DOUBLE-WAY FEED, WHICH IS INTENDED FOR OPERATION IN POWER RANGE OF 20 MVA TO 500 MVA AND HIGHER Russian patent published in 2015 - IPC H02K1/28 

FIELD: electricity.

SUBSTANCE: invention relates to a rotating electrical machine, namely to an asynchronous machine of double-way feed, which is intended for operation in the power range of 20 MVA to 500 MVA and higher. The electrical machine can be rotated about an axis of a rotor concentrically enveloped by a stator; the rotor has rotor housing (14) made of metal sheets that are located layer-by-layer and pressed to each other in axial direction into a package by means of clamping plate (19); the above rotor housing is divided in radial direction into internal mechanical zone (14b) and external electrical zone (14a), and rotor winding (18) is installed in electrical zone (14a) of the above rotor housing. Axial stress of the rotor housing of such a machine, which is made of metal sheets, is optimised by the fact that clamping plate (19) in accordance with radial separation of rotor housing (14) made of metal sheets is divided radially into a separate internal clamping plate and a separate external clamping plate.

EFFECT: improvement of the design.
