La présente invention concerne un couplage à aimant permanent à chaudière-grille ajustable avec couple électromagnétique de haute efficacité, qui affiche une structure de type à disque rotatif. Il est composé d'au moins un groupe de modules de couplage à aimant permanent et armature de chaudière-grille avec champ magnétique axial, d'au moins un ensemble d'un mécanisme de couplage de disque rotatif de couplage à aimant permanent d'entraînement et d'un joint de couplage d'axe d'entraînement correspondant (310) adaptés à un disque rotatif d'entraînement (70) dans les modules de couplage à aimant permanent, d'au moins un ensemble d'un mécanisme de couplage de disque rotatif de couplage à aimant permanent entraîné et d'un joint de couplage pour axe entraîné correspondant (311) qui conviennent pour un disque rotatif de couplage à aimant permanent entraîné dans les modules de couplage à aimant permanent, d'un ensemble de mécanismes de régulation des écartements du disque rotatif de couplage à aimant permanent et d'un ensemble de mécanismes d'assemblage intégrés (315, 317) qui intègre le système dans une structure intégrée convenant à l'emballage, au transport et à l'installation. Le couplage à aimant permanent convient aux domaines techniques de l'entraînement par couplage d'axe de transmission, de régulation de la vitesse de charge et de l'extraction de puissance.
