Abstract
A distributed winding for an electric machine may include a coil body with numerous grooves distributed over its circumference, where there are at least two poles for the winding, where there are at least two parallel winding strands for each pole, where each winding strand is composed of at least one wire, which has at least one groove region that runs axially in a groove and a connection region at both ends, where the connection regions protrude axially above the coil body, where each winding strand has contact pins that form connection regions on both ends, and where at least some of the contact pins in the same phase are located in adjacent grooves. That at least one of the adjacent contact pins in the same phase may be bent along the circumference in order to minimize the spacing between the contact pins.
