Stator for a housing-free dynamoelectric rotary machine

A housing-free dynamoelectric rotary machine, comprising:

• a stator having a material layer structure which comprises a plurality of material layers arranged in a row along a rotation axis, said material layer structure comprising a plurality of thickenings and a plurality of slots, with each of the slots arranged between two opposing surfaces of the thickenings;
• with at least one of the slots having a first projection disposed on a radial end of a first one of the two opposing surfaces and directed in a rotation direction, and a second projection disposed on a radial end of a second one of the two opposing surfaces and directed against the rotation direction;
• a slot wedge received in the at least one slot and captively secured in the at least one slot by the first and second projection, said slot wedge further comprising an axial bore;
• an end element arranged on an axial end of the stator and comprising a connection box for supply with electrical energy;
• and
• a connecting element designed to connect the end element to the axial bore of the slot wedge,
• wherein axial end is a front axial end or a rear axial end of the stator and the slot wedge is arranged spaced from the axial end of the stator.
