FIELD: electrical and electromechanical engineering; large electrical machines such as turbogenerators.
SUBSTANCE: proposed rotor has alignment ring assembled of internal and external rings joined together; several rows of tangential slits are made in one of them so that jumpers between slits of one row are disposed opposite intermediate part of other-row slits. In this case, on one hand provision is made for making one of mentioned rings as flexible insert for alignment ring, for instance by producing it from spring steel; on other hand, rotor shroud rings of large electrical machines can be designed so that single-seat overhanging mechanical design of shroud-ring assembly is actually transformed into double-seat assembly by placing internal ring in the form of flexible insert into mentioned assembly, and vice versa.
EFFECT: enhanced rotor reliability due to additional reduction of alternate stress in vicinity of setting shroud rings on rotor core.
