Abstract

A method for manufacturing a radial centering surface on an outer circumference of an annular laminated core of a stator comprises the steps of forming a stator with a hollow cylinder from strip-shaped laminations, preloading the stator axially before and during cutting, creating centering surfaces on an outer circumferential of the stator by using at least two cutting tools.
