1. A stator for a rotating electric machine, the stator comprising:
a stator core which has a plurality of slots arranged in a circumferential direction of the stator core; and
at least a first conductor and at least a second conductor arranged next to each other along a radial direction of one slot of the plurality of slots, wherein:
axial end sections of the first and second conductors are free from a separate insulating member,
the axial end sections are axially delimited by a proximal end directed towards the stator core and by a distal end directed away from the stator core, and
the axial end sections of the radially adjacent first and second conductors are distanced from each other, characterized by:
the axial end sections being axially distanced from each other, wherein an axial distance between a proximal end of the axial end section of a first conductor and an axial surface of the stator core is longer than the distance between a distal end of the axial end section of the second conductor and the axial surface of the stator core, and
each respective slot of the plurality of slots providing respective compartments formed by respective distancing members such that the first and second conductors are radially distanced from each other by the respective distancing members in respective slots.
