摘要： A stator for a rotary electric machine, a method for producing the stator, and the rotary electric machine. The stator has a body with a plurality of stator teeth arranged in a circumferential direction; grooves between the stator teeth; and conductor sections, arranged in the grooves, of at least one conductor pair which forms at least a portion of windings. In each groove, conductor sections are arranged along the groove depth parallel to and offset from one another and the sequence of the arrangement of the parallel conductor sections in each groove alternates in the circumferential direction. The conductors of the conductor pair, deviating from a winding direction extending basically circumferentially, meander in a radial direction, and via an enlacement formed thereby in each case, enlace around one group of stator teeth. The stator enables a high power density and a high degree of efficiency along with low installation space requirements.
