Electric motor stator comprising compact windings and method for manufacturing such a stator

An electric motor stator includes a magnetic circuit having a plurality of radial polar protuberances. The stator has, for all or some of said protuberances, a set of conductive zones in the general shape of a U, disposed around the protuberance, and the ends of each of the conductive zones are located in the vicinity of a common plane. The stator also has at least one connection component including a plurality of conductive tracks connected to distinct ends of said conductive zones, so as to define a DC electric circuit forming a winding around one or more radial polar protuberances.
