Patent

CA 2491421

The invention concerns an electrical machine, whereof the active part includes a global solenoid winding (110, 210, 310) for each phase and includes, inside said winding(s), a stack of ferromagnetic or non-magnetic parts (400) and magnetized parts (500), the ferromagnetic or non-magnetic parts being provided with passages traversed each by at least one relatively sliding element (600), each sliding element constituting a succession of portions alternately magnetic (620) and non-magnetic (630), the passages formed in the ferromagnetic or non-magnetic parts of the stack forming orifices whereof the internal cross-section encloses each time one sliding element, the sliding elements (600) consisting in rods having each an outer periphery matching the internal cross-section of the traversed orifices.

L'invention concerne une machine électrique, la partie active comprenant un bobinage solénoïdal global (110, 210, 310) pour chaque phase et comprenant, à l'intérieur de ce ou ces bobinages, un empilage de parties ferromagnétiques ou amagnétiques (400) et de parties aimantées (500), les parties ferromagnétiques ou amagnétiques étant munies de passages traversés chacun par au moins un élément en coulissement relatif (600), chaque élément coulissant incluant une succession de portions alternativement magnétiques (620) et amagnétiques (630), les passages formés dans les parties ferromagnétiques ou amagnétiques de l'empilage formant des orifices dont la section interne entoure à chaque fois un élément coulissant, les éléments coulissants (600) étant des tiges ayant chacune un pourtour externe complémentaire de la section interne des orifices traversés.
