Abstract
A stator of an electric machine of the power saving interval may include a stator core having a plurality of slots, and a stator winding wound around the slot, wherein the stator winding has a plurality of winding portions connected in parallel with one another for each phase, and each of the winding portions has a segment conductor inserted into three or more slots for each pole. As a result, it may be possible to increase the number of rotations and reduce the external size thereof while maintaining the same output.
