A modular motor and magnetic bearing assembly comprises a positioning casing (1) having a plane reference surface (17), an outer cylindrical reference surface (15), a central portion provided on an outer face with cooling liquid flow channels (11), and intermediate portions provided with openings (18, 19) for gaseous fluid entry and exit; a rotor (4) presenting an inner cylindrical reference surface (41) and a plane reference surface (42); an electric motor (6); radial magnetic bearings (7, 8); an axial abutment (3); and auxiliary mechanical bearings (91, 92). The modular assembly can then be incorporated in a main casing (150) simply by sliding and it can be connected directly to a functional unit (250) without reworking adjustments of the magnetic bearings (3, 7, 8). |
