A stator for an electric machine includes a cylindrical stator body having several stator slots. A first coil is inserted into the stator slots for a first phase, where the first coil has a first coil end on at least one face of the stator body. A second coil is inserted into the stator slots for a second phase, where the second coil has a second coil end on the at least one face of the stator body. A third coil may be inserted into the stator slots for a third phase, where the third coil has a third coil end on the at least one face of the stator body. The stator includes a molded body for receiving and electrically insulating the coil ends, where the molded body extends in a first ring area and a second ring area concentric with respect to the first ring area.

Stator with phase insulation for an electric machine and production method for such a stator

A method is provided for self-pierce riveting which reduces a setting force required for setting the rivets. For this purpose, a clamping force produced by a clamping device is substituted by the force produced by a rivet on a punch. The clamping force varies within a known magnitude, whereas the setting force is reduced by 20%.
