Stator for an electrical machine and electrical machine

A stator for an electrical machine, having a stator core, in which are formed a multiplicity of grooves that are distributed along a circumferential direction, and which has two end sides that are mutually opposite in an axial direction, and a stator winding that has a multiplicity of shaped conductors, wherein

• the shaped conductors have in each case one first leg portion, one second leg portion and one head portion which connects the leg portions in an electrically conductive manner on one of the end sides;
• wherein
• the leg portions of a respective shaped conductor extend through different grooves and are spaced apart from one another by an increment of a number of grooves;
• wherein
• the head portion has an inner portion which extends in the circumferential direction and adjoins the first leg portion, and an outer portion which extends in the circumferential direction, adjoins the second leg portion and is disposed radially further outward than the inner portion;
• wherein
• the increment in a first and a second of the shaped conductors is S, in a third of the shaped conductors is at least one greater than S, and in a fourth of the shaped conductors is at least one smaller than S, where S is a natural number,
• wherein
• in that the head portion furthermore has an offset portion which connects the inner portion to the outer portion and has a greater radial extent than the inner portion and the outer portion;
• and
• in that the outer portion of the head portion of the third shaped conductor runs at least partially radially further outward than the outer portions of the head portions of the first, the second and the fourth shaped conductor.
