▎ 摘  要

NOVELTY - The component (1) has a component portion (2) that is set with a laminated core, which is set with several teeth (3) and grooves (4) formed between the teeth. The electrical conductors of an electrical winding (7) are arranged in several of the grooves. The several conductor strands (11) are designed as electrical conductors, made of copper, aluminum, carbon nanotubes or graphene. An electrically insulating matrix material (12) embeds the conductor strands. A cured thermosetting molding compound is extended with a longitudinal extent and a certain cross-sectional shape through the grooves of the component portion. Conductor strands of pultrusion profiles from different grooves are connected to one another by connecting conductors (15), soldered, welded or glued, so that the electrical winding is formed. USE - Component such as rotor or stator of electrical machine (claimed) such as electrically excited synchronous machine. ADVANTAGE - The production of the electrical winding is simplified by pultrusion profiles being inserted into the grooves. The thermal conductivity is performed to improve the heat dissipation from the conductor strands of the pultrusion profile, the mechanical properties can be ensured to improve the speed stability and the thermal expansion coefficient is set to improve the bond with thermal expansion. The high speed stability of the rotor is achieved. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the component of electrical machine.
