Interaction between a spray-insulation for phase separation in the winding head and the following impregnation process in insertion winding stators

As part of the secondary insulation system for insertion winding stators, a new method was developed to apply the interphase insulation in the winding head. This invention is based on a robot guided spraying process that applies a plastic insulation layer on to the respective winding parts in the stator winding head. With an initial material selection and the construction of a prototype machine, t...
