Interconnection unit and method for producing a winding system

A method for producing a winding system of an assembly of an electrical machine with winding arrangements to be contacted-connected to one another, the method comprising:

• arranging each winding arrangement of the winding arrangements at a final position on the assembly of the electrical machine, wherein contact points of the winding arrangements are not connected to one another;
• arranging a plurality of contact points of at least one connection arrangement on an interconnection unit in such a way that the plurality of contact points of the interconnection unit enter into electrical contact and are contact-connected to the contact points of the winding arrangements;
• and
• arranging a plurality of electrical connection sections of the at least one connection arrangement, wherein a respective electrical connection section electrically connects a first contact point of the plurality of contact points of the respective electrical connection section with a first winding arrangement of the winding arrangements and connects a second contact point of the plurality of contact points of the respective electrical connection section with a second winding arrangement of the winding arrangements,
• wherein each contact point of the plurality of contact points of the interconnection unit is configured to be plugged onto a respective contact point of a winding arrangement of the winding arrangements.

A winding system comprising:

• a plurality of winding arrangements;
• and
• an interconnection unit comprising at least one connection arrangement having:
• a plurality of contact points configured and arranged on the interconnection unit in such a way that the plurality of contact points of the interconnection unit is configured to be contact-connected to contact points of the winding arrangements;
• and
• a plurality of electrical connection sections, wherein a respective electrical connection section electrically connects a first contact point of the plurality of contact points of the respective electrical connection section with a first winding arrangement of the winding arrangements and connects a second contact point of the plurality of contact points of the respective electrical connection section with a second winding arrangement of the winding arrangements,
• wherein each contact point of the plurality of contact points of the interconnection unit is configured to be plugged onto a respective contact point of a winding arrangement of the winding arrangements, and
• wherein the interconnection unit is configured and electrically contact-connected by way of the contact points of the interconnection unit to contact points of the winding arrangements in such a way that a prespecified series and/or parallel connection of at least one prespecified subset of the winding arrangements results.
