Abstract: A process for mounting magnets in an electric motor rotor and an electric motor rotor, said rotor comprising: a lamination stack (10) provided with a plurality of axial channels (12) disposed around a central axial bore (11) and housing permanent magnets (20); and a rotor cage (30) formed by a pair of end rings (31), each seated against an adjacent end lamination of the lamination stack (10) and interconnected by a plurality of bars (32), said process comprising the steps of: forming an end, ring (31) with at least one inner radial projection (33) disposed radially external to the projection of the contour of an axial channel (12); mounting in each axial channel (12) at least one permanent magnet (20); and deforming each inner radial projection (33) in order to increase its radial extension the sufficient to radially cover at least part of the projection of the contour of said axial channel (12), defining a stop for axially retaining the respective permanent magnet (20).

Abstract: A system for closing a suction muffler of a hermetic compressor, the suction muffler including: a hollow base; a cover to be coupled to the hollow base, the parts defined by the hollow base and the cover including respective mutually seatable peripheral flanges, which are shaped to define, jointly, an internal channel extended along at least part of the circumferential extension of the peripheral flanges and which is opened to the opposite external faces of the latter by means of throughbores axially aligned to each other in pairs, each pair of throughbores maintaining a circumferential distance in relation to an adjacent pair of throughbores, the throughbores of each pair and the internal channel being filled with a gasket of injected material, which projects outwardly from the throughbores so as to define an axial lock portion
