A stator core (11) is mounted on a fixed member (22), and electric connections are made to assemble a first submodule (20). On the other hand, a rotor core (12) is mounted on a rotational member (21), and electric connections are made to assemble a second submodule (30). To complete an isolation transformer, the first submodule and the second submodule are united in such a manner that the stator core and the core rotor are opposed to each other. A shaft (21) held in the fixed member for carrying the rotor core includes a guide member (27) having a first reference surface for radial directions and a second reference surface for axially directions. The guide member is used to set the shaft position between the cores and the gap length (g) accurately by adjusting the positions of the cores.

D'après cette invention, un noyau stator (11) est monté dans un premier temps sur un élément fixe (22), tandis que des connexions électriques sont effectuées afin d'assembler un premier sous-module (20). Un noyau rotor (12) est ensuite monté sur un élément rotatif (21), tandis que des connexions électriques sont effectuées afin d'assembler un second sous-module (30). Afin de former un transformateur d'isolation, le premier et le second sous-modules sont réunis de manière que le noyau stator et que le noyau rotor soient opposés l'un à l'autre. Un arbre (21), qui est maintenu dans l'élément fixe et qui va supporter le noyau rotor, comprend un élément de guidage (27) qui possède une première surface de référence pour les directions radiales ainsi qu'une seconde surface de référence pour les directions axiales. L'élément de guidage permet de définir précisément la position de l'arbre entre les noyaux ainsi que la longueur (g) du jour, ceci en ajustant les positions desdits noyaux.
