MULTI-MATERIAL ROTOR OR STATOR POLE FOR ELECTRIC MOTORS AND GENERATORS AND METHOD FOR MANUFACTURING SUCH POLES

摘要

The invention relates to a rotor and stator pole for respectively a rotor and a stator for an electric motor or generator wherein the rotor and stator comprise respectively a rotor and a stator body with each a number of poles, wherein the rotor pole comprises a segment of a non-magnetic material and a segment of an electrical steel and the stator pole a segment of a non-oriented electrical steel and a segment of a grain-oriented electrical steel. The invention also comprises a method to make rotor poles and stator poles for a rotor or stator for an electric motor or generator.
