Les aimants segment\u00e9s NdFeB sont des composants sp\u00e9cialis\u00e9s en forme de tuile con\u00e7us pour des configurations de magn\u00e9tisation multipolaires. Dans la conception moderne des moteurs, augmenter le nombre de p\u00f4les peut augmenter le couple et fournir une rotation plus douce \u00e0 des vitesses plus basses. Ces segments facilitent la construction de rotors \u00e0 4 p\u00f4les, 8 p\u00f4les, ou m\u00eame avec un nombre de p\u00f4les plus \u00e9lev\u00e9, en alternant simplement la polarit\u00e9 (Nord\/Sud) des segments adjacents lors de l'assemblage.<\/p>\n

Ces segments pr\u00e9sentent une excellente pr\u00e9cision d'orientation magn\u00e9tique. Une orientation mal align\u00e9e peut entra\u00eener des performances moteur irr\u00e9guli\u00e8res, nous veillons donc \u00e0 ce que l'axe magn\u00e9tique soit parfaitement perpendiculaire \u00e0 la corde ou align\u00e9 radialement, selon les sp\u00e9cifications. Les segments sont disponibles en diff\u00e9rents degr\u00e9s d'arc (par exemple, 30\u00b0, 45\u00b0, 60\u00b0) pour former un anneau complet de 360\u00b0. Ils sont \u00e9galement optimis\u00e9s pour minimiser les pertes par courants de Foucault, qui peuvent chauffer l'aimant et d\u00e9grader les performances dans les applications \u00e0 haute fr\u00e9quence.<\/p>\n

NdFeB Segment Magnets are specialized tile-shaped components designed for multipole magnetization configurations. In modern motor design, increasing the number of poles can increase torque and provide smoother rotation at lower speeds. These segments facilitate the construction of 4-pole, 8-pole, or even higher pole-count rotors by simply alternating the polarity (North\/South) of adjacent segments during assembly.
