Abstract
A containing casing for a stator of an electric machine defines, around said axis, a compartment to house the stator. A first radially inner part and a second radially outer part are coupled to one another and define together at least one duct surrounding the axis for the passage of a cooling fluid. Said duct comprises, in turn, a plurality of first sections and a plurality of second sections, which are distributed around the axis alternated with one another. The first sections are arranged around the axis with an arrangement that supports the motion of the fluid around the axis. The second sections are transverse to the first sections and at least partially obtained inside respective protuberances of the first radially inner part, which project towards the inside of the compartment. A space for the insertion of radially projecting portions of electric windings of the stator is defined between two consecutive protuberances around the axis.
