Shell-less motor and manufacturing method thereof

Abstract

The invention relates to an electric rotary machine (1), in particular a housing-free electric machine, having a magnetically conductive hollow cylindrical body, in particular a laminated core (25) consisting of axially layered metal sheets, as a stator (2), the invention relates to a stator (2) for a motor vehicle, comprising a hollow cylindrical body (1), in which slots (5) face the inner circumferential surface (18) of which slots a winding system (21) is arranged, which forms winding heads (I, II) on the end faces (III, IV) of the hollow cylindrical body, i.e. The stator (2), said winding heads (I, II) being surrounded at least in some sections by semi-laterally open ring-shaped bearing caps (8, 26), the bearing cap (8) is closed by end faces (III, IV) of the hollow cylindrical body at least in a radially outer region of the hollow cylindrical body.
