Title (EN) PERMANENT MAGNET BRAKE AND SERVO DRIVE MOTOR
(FR) FREIN À AIMANT PERMANENT ET SERVOMOTEUR D'ENTRAÎNEMENT
Abstract:
(EN) A permanent magnet brake (1) includes a first brake pad (2) and the brake disc is arranged on a first side of the stator (3), the stator (3) further comprises a stator yoke (4), a stator yoke (4) on the side facing the first brake pad (2) is provided with a spring hole (7), a spring (8) is arranged in the spring hole (7); a coil (5) disposed in the stator yoke (4), and a permanent magnet (6), arranged on the stator yoke (4), wherein the first brake pad (2) includes a ferromagnetic body. A servo drive motor includes motor, output shaft and a permanent magnet brake (1).The permanent magnet brake (1) may utilize a forward pulse current or a reverse pulse current to achieve permanent magnetic brake (1) of a brake and brake release.
(FR) L'invention concerne un frein à aimant permanent (1) comprenant une première plaquette de frein (2), le disque de frein étant disposé d'un premier côté d'un stator (3), le stator (3) comprenant en outre une culasse (4) de stator, la culasse (4) de stator, du côté faisant face à la première plaquette de frein (2), étant munie d'un trou (7) de ressort, un ressort (8) étant disposé dans le trou (7) de ressort ; une bobine (5) disposée dans la culasse (4) de stator, et un aimant permanent (6) disposé sur la culasse (4) de stator, la première plaquette de frein (2) comprenant un corps ferromagnétique. Un servomoteur d'entraînement comprend un moteur, un arbre de sortie et un frein à aimant permanent (1). Le frein à aimant permanent (1) peut utiliser un courant d'impulsion vers l'avant ou un courant d'impulsion inverse afin d'obtenir le serrage et le desserrage d'un frein magnétique permanent (1).
