Abstract (en)
[origin: WO2007036956A1] A yoke structure for supporting and compressing the magnetic lamination core (32) of a static electrical machine, comprises at least four stress traverses (1-2, 34) tightened in pairs over the top branch and over the bottom branch of a lamination pack (32). Each stress traverse (1, 2, 3, 4) is composed of at least two tubular members (9) of rectangular cross section, parallel and spaced from one another and joined together by a plurality of brackets (11) having side wings with apertures to slidely receive there through the tubular members (9). At least two pairs of brackets (11) constitute supporting and blocking brackets for the resin body (29) encapsulating the windings of the electrical machine. The two outermost brackets (11) of each stress traverses (1, 2, 3,4) receive their said wings stress washers (12) for tie rods (5, 6, 7, 8) used to tighten the stress traverses.
