Abstract: An electrical machine includes a tubular rotor magnetised to have circumferential polar alternations, and a stator including a body that is traversed by a channel having an inner transverse section that substantially corresponds to the outer transverse section of the rotor, the body carrying a plurality of windings, the stator being surrounded by an outer ferromagnetic envelope, the body being extended by three, four or six radial projections made from an electrically insulating material having, in the transverse cross section, a longitudinal core for receiving a winding, the core being extended by a peripheral extension having an outer surface that matches the inner surface of the envelope and covers the wound area. A method for producing such an electrical machine is also provided.

Abstract: The disclosure relates to a valve for controlling the circulation of a fluid, having a valve body and a housing containing an electric motor composed of a stator and of a rotor, a needle, a sealing bell and also a fixed screw or a fixed nut. The fixed screw or the fixed nut is secured to the valve body, and the stator is secured to the valve body via the housing. The sealing bell is positioned at the interface between the rotor and the stator in such a way that the screw/nut, the rotor and the needle are within this bell and submerged in the fluid, the stator being isolated from the fluid. Furthermore, the rotor has the function of a nut or of a screw, and has a helical movement imposed by the fixed screw or the fixed nut and drives the needle axially. The motor is a brushless polyphase motor with radial principal magnetic flux.
