(FR) MOTEUR DE VIBRATION À COURANT CONTINU SANS BALAIS

Abstract: front page image
(EN)A brushless direct current vibration motor is provided. An eccentric weight arranged in a rotor is fixed between a back yoke and a permanent magnet such that both upper and lower surfaces of the eccentric weight are firmly fixed. The weight of the eccentric weight increases up to an area of the upper side of the permanent magnet such that vibration amount increases. Stopping protrusions for preventing the separation of a bearing are arranged on the upper end and the lower end of a bearing coupling part. In a bracket, a cogging plate mounting part is formed in a groove shape instead of a hole shape such that the support power of the entire bracket is high. A plate separation prevention protrusion is arranged on the upper end of a cogging plate receiving groove such that a cogging plate can be firmly mounted in the bracket. Cogging plate pieces are connected into one body so as to be simply mounted in the bracket all at once. Since a cogging plate area is minimized, the rising of a rotor is suppressed when a motor is driven, thereby preventing frictional noise between the rotor and an upper case, and a stopping speed of the rotor, which is being rotated, is improved such that residual vibration does not remain. In addition, the horizontal level of the rotor which is being rotated can be uniformly maintained.
(FR)L'invention concerne un moteur de vibration à courant continu sans balais. Un poids excentrique disposé dans un rotor est fixé entre une culasse arrière et un aimant permanent de telle sorte que les surfaces supérieure et inférieure du poids excentrique soient toutes deux solidement fixées. La masse du poids excentrique augmente jusqu'à une zone du côté supérieur de l'aimant permanent de sorte que le volume de vibration augmente. Des protubérances d'arrêt destinées à empêcher la séparation d'un palier sont disposées sur l'extrémité supérieure et l'extrémité inférieure d'une partie de couplage de palier. Dans une ferrure, une partie de montage de plaque à denture est réalisée en forme de rainure au lieu d'une forme de trou, de sorte que le pouvoir de support de la ferrure entière soit élevé. Une protubérance de prévention de séparation de plaque est disposée sur l'extrémité supérieure d'une rainure de réception de plaque à denture, de sorte qu'une plaque à denture peut être solidement montée dans la ferrure. Les pièces de la plaque à denture sont reliées en un seul corps de manière à être montées en toute simplicité dans la ferrure toutes à la fois. Du fait qu'une surface de la plaque à denture est réduite au minimum, la montée d'un rotor est supprimée lorsqu'un moteur est entraîné, ce qui empêche un bruit de frottement entre le rotor et un carter supérieur, et une vitesse d'arrêt du rotor en cours de rotation est améliorée de sorte qu'il ne reste pas de vibrations résiduelles. De plus, le niveau horizontal du rotor qui est mis en rotation peut être maintenu de manière uniforme.
(KO)브러시리스 직류 진동 모터가 제공된다. 회전자에 배치된 편심추를 백 요크와 영구자석의 사이에 고정시켜 편심추의 상하 양면이 견고하게 고정된다. 편심추의 중량을 영구자석 상측의 면적만큼 증가시켜 진동량을 높인다. 베어링 결합부의 상단과 하단에 베어링의 이탈을 방지하는 걸림턱이 마련된다. 브라켓에는 코깅 플레이트 장착 부위를 구멍 대신 홈 형태로 만들어 브라켓 전체의 지지력이 높다. 코깅 플레이트 수납홈의 상단에는 플레이트 이탈방지턱이 마련되어 코깅 플레이트가 브라켓에 견고하게 장착될 수 있다. 코깅 플레이트 조각들이 한 몸체로 연결되어 한꺼번에 간편하게 브라켓에 장착될 수 있다. 코킹 플레이트 면적을 최적화함으로써 모터 기동 시 회전자의 상승을 억제하여 회전자와 상부 케이스 간의 마찰 소음이 방지되고, 회전 중인 회전자의 정지 속도를 향상시켜 잔진동이 남기지 않는다. 또한, 회전 중인 회전자의 수평 레벨을 균일하게 유지할 수 있다.
