ROTOR WITH INSERT PART Russian patent published in 2018 - IPC H02K17/16 H02K15/02 

FIELD: electricity.

SUBSTANCE: rotor comprises a sheet bag including axially disposed steel sheets and a groove. The sheet bag and the groove extend axially from the first axial end to the second axial end along the axis of rotation. The groove comprises filling of the groove from the first material having a metal element of the periodic system of elements. Herewith the filling of the groove has a cast metal zone passing the end zone at the first axial end in the first direction perpendicular to the axial direction, at least, in part, beyond the sheet bag. The cast metal zone passes through the groove and fills the first groove part with the first material in the first direction perpendicular to the axial direction. The insert part in the first direction perpendicular to the axial direction fills the second part of the groove with the second material having a metal element of the periodic system. The insert part and the cast metal zone are connected to the closure of the material by means of a connecting zone. The connecting zone has another metal element of the periodic system.

EFFECT: improving the quality of the rotor.
