Abstract
An essentially elongated strip is formed for manufacturing a ring-shaped element of an electrical machine. The strip has an electromagnetic effective area which is oriented perpendicularly to an axis of rotation of the ring-shaped element. The strip is essentially elongated, and has segments which are separate from one another and together form the effective area of the element. Adjacent segments are directly connected in each case by a web which is integrally formed on the outside of the element. The web is formed in such a way that it absorbs an elastic deformation during the bending of the strip, whereas the segments remain essentially free of elastic deformation.
