    摘要: Disclosed are a welded structure and a welding method which make it possible to improve welding strength and welding quality. A welded structure in which a first member and a second member are joined by means of welding, wherein the first member comprises a second-member joining part which is joined to the second member, and the second member comprises a first-member joining part which is joined to the first member. If the direction in which the first member and the second member are arranged is the first direction, and the direction intersecting the first direction is the second direction, the welded structure comprises a cavity part which is provided between the first-member joining part and the second-member joining part, and a welded part which is provided between the cavity part and both end parts in the second direction of the joining surface where the first-member joining part and the second-member joining part are joined.

    摘要: An electric motor (10) comprising:
    - a rotor member (16) rotatably coupled to a rotation shaft (20) of longitudinal axis (X) and a surrounding stator member (18) comprising a first and a second opposite winding heads (18b,18c) having each inner and outer radially located sides,
    - a cooling system (CS) comprising:
    a cooling fluid pipe (24) arranged above the stator member and having cooling fluid projecting orifices (24a-c) for projecting cooling fluid downwardly towards the outer side (18b1) of a winding head (18b),
    a rotating member (26) rotatably coupled to shaft (20) and having an outer peripheral surface (26a) arranged inwardly relative to the inner side (18b2), the rotating member (26) configured to collect on its surface (26a) cooling fluid that has flown downwardly through the winding head from its outer side to its inner side and to distribute collected cooling fluid towards the latter by centrifugal force, while the rotating member (26) rotates.
