Rotational cutting of lamination sheets for electrical machines

The workflow for processing laminations is such an innovating field. Every piece of the lamination stack for rotor and stator is cut at least one or several times. For this complex aim, mechanical cutting press systems with eccentric drives are widely used. This paper presents a new approach towards continuous rotational cutting compared to traditional press systems with vertical tools. This approach has advantages towards machine masses, production speed, tool flexibility and new materials. A machine prototype is presented and a production benchmark between these two technologies is given.
