Title
(EN) MAGNETICALLY-COUPLED TORQUE-ASSIST APPARATUS
(FR) APPAREIL D'ASSISTANCE DE COUPLE À COUPLAGE MAGNÉTIQUE
Abstract
(EN) A magnetically-coupled torque assist apparatus includes a movable (rotor) magnet configured to rotate about a rotor magnet axis extending through the rotor magnet, and a stationary (stator) magnet. The rotor magnet and the stator magnet have a gap therebetween. There is an equilibrium state position (ESP) of the rotor magnet where forces acting on the rotor magnet are balanced such that the rotor magnet is stationary about the rotor magnet axis. And when the rotor magnet is rotated from the equilibrium state position (ESP) to an elastically stressed state position (SSP), magnetic fields of the rotor magnet and the stator magnet generate a resultant magnetic force on the movable magnet that biases the movable magnet towards the equilibrium state position. In some embodiments, the stator and rotor magnets are configured to create a Halbach-effect magnetic field bloom, which contributes to the magnetic forces.
(FR) Un appareil d'assistance de couple à couplage magnétique comprend un aimant mobile (rotor) conçu pour tourner autour d'un axe d'aimant de rotor s'étendant à travers l'aimant de rotor, et un aimant fixe (stator). L'aimant de rotor et l'aimant de stator ont un espace entre eux. Il y a une position d'état d'équilibre (ESP) de l'aimant de rotor où les forces agissant sur l'aimant de rotor sont équilibrées de telle sorte que l'aimant de rotor est immobile autour de l'axe d'aimant de rotor. Et lorsque l'aimant de rotor est tourné depuis la position d'état d'équilibre (ESP) à une position d'état de contrainte élastique (SSP), des champs magnétiques de l'aimant de rotor et de l'aimant de stator génèrent une force magnétique résultante sur l'aimant mobile qui sollicite l'aimant mobile vers la position d'état d'équilibre. Dans certains modes de réalisation, les aimants de stator et de rotor sont conçus pour créer une efflorescence de champ magnétique par effet de Halbach, qui contribue aux forces magnétiques.
