FIELD: electrical equipment.
SUBSTANCE: invention relates to electrical equipment. Rotating electric rotor comprises core having the through hole and shaft. Shaft has female helical portion on the first side and the core receiving portion on the second side. Rotor core one end portion is in contact with the rotor shaft core receiving portion. Washer has annular structure with the elastically deformable in the radial direction cutouts. Washer surface in contact with the core second end face has conical surface and annular projecting portion, which is attached to the rotor core. Annular projecting portion is fitted and fixed to the core through hole inner peripheral surface. Nut has female threaded portion, engages, attaches to the of the rotor shaft male helical portion and has first end surface contacting the washer conical surface. Nut first end surface is a conical surface, which side, located radially inwards towards the rotor shaft, projects to the washer side closer than the side located radially outwards from the rotor shaft.
EFFECT: improved rotor shaft and core connection.
