An electric motor for powering downhole tools comprises a first stator (33) including a first set of coil windings (73), a second stator including a second set of windings, an axially located rotatable shaft (92) including a first magnetic element and a second magnetic element, a sealed annular chamber defined by a first tube (96), and an second tube concentrically inside the first tube. The first and second stators are located in the annular chamber, and the first magnetic element being aligned with the first stator such that the first stator when energised can act upon the first magnetic element, and the second magnetic element being aligned with the second stator such that the second stator when energised can act upon the second magnetic element.

L'invention concerne un moteur électrique, destiné à alimenter en énergie des outils en fond de puits. Il comprend un premier stator (33) comportant un premier ensemble d'enroulements de bobine (73), un second stator comportant un second ensemble d'enroulements, un arbre tournant disposé axialement (92) comportant des premier et second éléments magnétiques, une enceinte annulaire étanche définie par un premier tube (96), et par un second tube disposé de façon concentrique à l'intérieur du premier tube. Les premier et second stators sont placés dans l'enceinte annulaire, le premier élément magnétique étant aligné avec le premier stator de façon à ce que lorsque le premier stator est excité, il agisse sur le premier élément magnétique, le second élément magnétique étant aligné avec le second stator de façon à ce que lorsque le second stator est excité, il agisse sur le second élément magnétique.
