Stator of an axial flux electric machine comprising a cooling device and an electric machine equipped with this stator

Abstract

A stator of an axial flux electric machine comprising a cooling device and an electric machine equipped with this stator. One aspect of the invention relates to a stator of an axial flux electric machine with an external bearing comprising at least a main body and a winding and a yoke (3) mounted against the main body or the winding. The yoke (3) comprises a one-piece body (37) mounted against an external face of the stator body and / or the winding and a cooling circuit (30) located at a maximum radius less than a minimum radius of a peripheral external surface of each stator tooth.The cooling circuit (30) comprises an inlet (301) and an outlet (302) and at least one conduit (300) having a first and a second end connected respectively to the inlet (301) and the outlet (302), the conduit (300) being formed by at least one wall of the monobloc body in thermal contact with only one external face of the stator body and / or the winding.
