Title (EN) MAGNETICALLY ACTUATED BRAKE
(FR) FREIN À ACTIONNEMENT MAGNÉTIQUE
Abstract:
(EN) A magnetic brake for a motor uses the magnetic force on the surface of a flux concentrating rotor to pull a flexible brake spring or friction sheet into friction contact with the rotor. An electromagnetic stator pulls the flexible brake spring or friction sheet away from the rotor when it is energized. The brake spring may be a variable thickness around the circumference in a radial flux motor or radially in an axial flux motor and is thicker near where it is fixed to the housing. The brake spring may be split so it can clamp down on the rotor symmetrically. The OD of the brake spring may be closer to the surrounding stator near the fixed section of the brake spring so the air gap to the brake stator is smaller and the gap to the rotor and the ID of the brake spring is larger to allow the brake stator to pull on this area with greater force initially when it is energized to disengage the brake.
(FR) L'invention concerne un frein magnétique pour un moteur, lequel frein utilise la force magnétique sur la surface d'un rotor de concentration de flux pour tirer un ressort de frein flexible ou une feuille de frottement en contact de frottement avec le rotor. Un stator électromagnétique tire le ressort de frein flexible ou la feuille de frottement de façon à l'éloigner du rotor quand il est excité. Le ressort de frein peut avoir une épaisseur variable autour de la périphérie dans un moteur à flux radial, ou radialement dans un moteur à flux axial, et est plus épais au voisinage de l'endroit où il est fixé au boîtier. Le ressort de frein peut être fendu, de telle sorte qu'il peut être serré sur le rotor de façon symétrique. Le diamètre externe du ressort de frein peut être plus proche du stator environnant au voisinage de la section fixe du ressort de frein, de telle sorte que l'entrefer vis-à-vis du stator de frein est plus petit, et que l'entrefer vis-à-vis du rotor, et le diamètre interne du ressort de frein, est plus grand, de façon à permettre au stator de frein de tirer sur cette zone avec une force initiale plus élevée quand il est excité pour désengager le frein.
