Stator with Phase Insulation for an Electric Machine and Production Method for Such a Stator

摘要

The invention relates to a stator for an electric machine, comprising a cylindrical stator body having several stator slots. At least one 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. At least one 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. And t least one third coil is 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 also comprises at least one molded body for receiving and electrically insulating the coil ends, wherein the molded body extends in a first ring area and a second ring area concentric with respect to the first ring area, on the at least one face of the cylindrical stator body, such that the at least one first coil end is arranged in the first ring area, the at least one third coil end is arranged in the second ring area, and the at least one second coil end is arranged in the first and in the second ring area.
