Abstract
A stator having a stator core which has two end sides disclosed. A multiplicity of grooves are configured in the stator core. A stator winding occupies a plurality of winding zones in the grooves, a number of N strands has a number of 2·P poles, and the number of grooves is 2·P·N·q, where q≥2. Each winding zone extends across at least q+1 of the grooves, and each winding zone is radially subdivided into first to Lth layers. The layers configure first to (L/2)th double layers, and a number of the double layers is less than the number of the other double layers. Each winding zone in the circumferential direction is subdivided into first to qth sub-winding zones, and a respective phase winding for one of the strands has at least one sub-winding which configures a current path and comprises internal portions that are disposed within the grooves.
