Laser manufacturing of electrical machines

Laser remote cutting for electrical machine application and a new surface treatment method in order to heal manufacturing related magnetic degradation will be presented and discussed. In comparison to the state of the art laser remote cutting utilizes a brilliant high power solid-state laser producing less thermal and magnetic degradation in the processed part. A process integrated surface treatment additionally reduces the manufacturing related magnetic degradation by up to ten percent. Matter under consideration will be the control of cycle time of exemplary stator tooth geometry as well as the magnetic properties in comparison to conventional techniques.
