Abstract
The aim of the invention is to increase the degree of automation in the production of an electrical machine. Particularly, the aim is to be able automate the connection of the coils of an electrical machine. For this purpose, provision is made for the coil ends (17) to be connected using at least one busbar (20, 22). The ends (23) of the respective busbars (20, 22) are hot crimped or welded to the associated end (17) of the coil. Thus, it is possible to eliminate manual drilling and welding of the coil ends. Moreover, the hot-crimped and welded connections have a high degree of electric strength and a high ampacity.

A stator of an electrical machine, comprising:
- a plurality of coils connected to one another on one side of the stator;
- and
- at least one busbar connecting two of the plurality of coils and having ends, one end of the at least one busbar being hot-crimped to one end of one of the coils and another end of the at least one busbar being hot-crimped to one end of the other one of the coils.
A method of interconnecting a stator of an electrical machine, comprising the steps of:
- inserting a plurality of coils into a laminated core of the stator;
- interconnecting the plurality of coils to one another on one side of the stator, wherein two of the plurality of coils are interconnected by at least one busbar;
- and
- hot-crimping one end of the at least one busbar to one end of one of the coils and hot-crimping another end of the at least one busbar to one end of the other one of the coils.
