Abstract

A method for producing a rotor includes providing lamella elements and arranging the lamella elements to form a lamella bundle where the lamella bundle has webs. End plates are arranged at respective end faces of the lamella bundle where the end plates axially support the lamella bundle. The lamella bundle is axially fixed or pretensioned by winding conductor material around the webs and a rotor shaft is arranged in the fixed or pretensioned lamella bundle.
