Abstract
The invention relates to an electric machine (1) having a stator (2), with magnetic-field-conductive material, in which substantially axial grooves (4) are positioned, wherein a winding system (3), which is surrounded and/or penetrated by impregnating resin, is provided in the grooves, wherein the impregnating resin has energy-absorbing particles (7).
Claims7
A method for producing an electric machine, comprising:
- providing a magnetic-field-conductive body with grooves;
- inserting a winding system into the grooves of the magnetic-field-conductive body;
- and
- impregnating the winding system with an impregnating resin containing substantially thread-shaped particles, wherein the particles in the impregnating resin forming, during or after impregnation of the winding system, a plurality of oscillation-absorbing structures, within the impregnating resin, by a physical and/or chemical process, such that the substantially-thread-shaped particles assume a spiral, helical, spherical, zigzag-shaped or skein configuration.
