Due to the design, the distances between the connection pins and the hairpin ends may be smaller, in particular in the area of the connection pins, or the distance from the hairpin ends to other electrically conductive components may be small at other points on the circumference, which is why insulation is necessary especially in these areas.

  • the base body In order to isolate the hairpin ends from one another, the base body, viewed in the axial direction of the electrical machine, has openings which extend over the thickness of the base body and are thus continuous. Due to the through openings, the air can escape when the hairpin ends are encapsulated, as a result of which air pockets and the like can be reliably avoided. At the same time, the insulation of the hairpin ends from one another, in particular with regard to the air gap to one another, is improved by the material of the base body present between the openings. Each opening is assigned a hairpin end or a pair of contacts made of interconnected conductor elements or a connecting pin.

  • Preferred insulation units are characterized in that the spacers are arranged distributed uniformly over the circumference. The minimum distance over the entire circumference is ensured by an even distribution and symmetries can be used.
  • Isolation units are characterized in that the spacers are not directly adjacent to an opening for a connection pin are arranged.
