An electric machine comprising:
- a stator which comprises a plurality of teeth having at least one needle-wound winding strand, the at least one winding strand having at least two windings on adjacent teeth which are arranged in series, the at least two windings each comprising at least one winding layer, wherein a needle channel is provided which is formed between the at least two windings by a crossing portion of the at least two windings and is filled at least in part.
A method of winding a coil of an electric machine, by means of a needle winder, comprising the steps of:
- providing a coil of a winding carrier having a plurality of teeth, the coil comprising at least two windings on adjacent teeth which are arranged in series and the at least two windings each comprising at least one winding layer;
- producing the respective at least one winding layer of a first of the at least two windings by winding a winding wire around a first tooth;
- producing the respective at least one winding layer of a second of the at least two windings by winding the winding wire around a second tooth;
- and
- producing the final winding layer by winding the winding wire around both the second tooth and the first tooth.
