摘要： An electric machine stator has a core of ferromagnetic material, consisting of a plurality of teeth arranged around a longitudinal axis and defining a plurality of slots between them; the stator has, for each tooth, an insulating cap fixed to a longitudinal end of the tooth by means of an interference coupling and provided with front projections facing and spaced apart from one another in a radial direction; the windings, which are made of electrically conductive material, extend in the half-slots arranged on opposite sides of each tooth and around the cap, between said front projections in a radial direction; each half-slot carries at least one sheet of foldable insulating material, which has a C-shaped portion, which is interposed between the first wire portions and the tooth, and at least one flap, which longitudinally projects from said C-shaped portion out of the corresponding half-slot and radially rests on an end portion that is part of one of said front projections.

摘要： An electric machine three-phase stator has a casing and three busbars that carry respective contacts, within and at an axial end of this casing; the contacts are electrically connected to respective outer terminals;
the stator is provided with an electrical connector, which is coupled, in a fluid-tight manner, to the same casing and has three connection conductor elements; the outer ends of the three conductor elements define the above-mentioned outer terminals, while the inner ends of the three conductor elements are respectively fixed to the contacts by means of a fixing system; the busbars, the contacts, fixing system, and the inner ends of the three conductor elements are embedded in an encapsulation material.-

摘要： Three-phase stator winding of a rotary electric machine and having: a plurality of coils each of which has two opposite ends; a plurality of first connection bridges, each of which defines a star connection of three coils and constitutes a star centre of the three coils by connecting a first end of each of the three coils to one another; and three second connection bridges which define a parallel connection of the star connections, are each provided with a corresponding pin defining a terminal of the three-phase stator winding towards the outside, and each of which connects a second end of a respective coil of each star connection to one another. Each second connection bridge has a seamless circular shape closed onto itself.

摘要： Electric machine having: a shaft; a rotor with permanent magnets that is fitted to the shaft; a stator having a magnetic core which consists of a series of laminations made of ferromagnetic material and longitudinally crossed by a plurality of stator slots; and a stator winding having a plurality of rigid bars that are inserted in corresponding stator slots and that are covered, on the outside, with an insulating coating. Each stator slot is completely free from an insulating element interposed between the ferromagnetic material making up the laminations of the magnetic core and the corresponding bars, so that an outer surface of the corresponding bars is in direct contact with an inner surface of the stator slot made of the ferromagnetic material.

摘要： A rotor for a rotary electric machine and having: a plurality of permanent magnets, which are axially oriented and are arranged beside one another around a rotations axis so as to form a closed ring; a support cylinder, which has an outer surface, on which the permanent magnets rest, and a central cavity; and two half-shafts, which are independent of and separate from one another and are singularly inserted in opposite ends of the central cavity of the support cylinder so as to form one single block with the support cylinder. The permanent magnets are circumferentially arranged one following the other according to a Halbach array so as to nullify the magnetic field radially on the inside of the permanent magnets and so as to maximize the magnetic field radially on the outside of the permanent magnets.
