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 current carrying capability.
