Abstract: A rotor for a rotary electric machine, including: a stack of magnetic laminations each having openings, the superposition of these openings within the stack forming slots, at least some of the openings having, on at least part of their periphery, friction reliefs, electrically conducting bars made of a first material, received in at least part of the slots and coming to bear via at least one principal face against said reliefs.

Abstract: A method for manufacturing a rotor of a rotary electric machine, including a stack of magnetic laminations defining the slots in which bars made from a first electrically conducting material are received, in which method a second electrically conducting material, different from the first, is injected using an injection machine, from the front of the laminations stack, the bars being held at their rear end against the pressure associated with the injection by a positioning tool that passes through a cavity used for forming a short-circuiting ring at the rear of the laminations stack.

Abstract: The present invention concerns a rotating electrical machine, comprising: a magnetic mass (2), in particular a rotor, comprising first housings (3), a plurality of permanent magnets (11) inserted into the first housings (3), and shims (20), preferably deformable, inserted into the first housings (3) and/or into second housings (12) provided in the magnetic mass (2), the shims (20) being configured to wedge the magnets (11) in the first housings by plastic and/or elastic deformation.

Abstract: Described are glycerol diesters of the general formula (I) wherein one of the two radicals R1 or R2 is hydrogen, and the radical of the two radicals R1 and R2 that is not hydrogen is a radical: and the radicals R3, R4, R5, and R6 independently of one another are a saturated, aliphatic radical having 1 to 20 carbon atoms, with the proviso that the radicals R3 and R4 together contain at least 5 carbon atoms and the radicals R5 and R6 together contain at least 5 carbon atoms. Also described is a process for preparing the glycerol diesters, use thereof as reactive diluents, coating materials comprising the glycerol diesters, multicoat paint systems and their production, comprising the use of the coating materials, and also to substrates coated therewith.
