Title (EN) SPINDLE MOTOR HAVING AN ELECTROSTATIC DISCHARGE PATH
(FR) MOTEUR À AXE COMPRENANT UN CIRCUIT DE DÉCHARGE ÉLECTROSTATIQUE
(KO) 정전기 방전 경로를 갖는 스핀들 모터
Abstract: front page image
(EN)The present invention relates to a spindle motor having an electrostatic discharge (ESD) path capable of safely discharging electric charges, introduced to a rotary shaft from an external source, to the outside via a base plate in a structure in which a bearing housing is made of a resin and the base plate is insert-molded. The spindle motor of the present invention comprises: a rotor having, to the center of which one end of a rotary shaft is coupled; a bearing that supports the rotary shaft such that the rotary shaft is rotatable; a bearing housing which has a groove in which the bearing is received, and which is made of a resin; and a base plate, the inner periphery of which is embedded in the bearing housing. A portion of the base plate contacts the bearing such that the static electricity introduced from an external source can be discharged to the outside through the rotary shaft, bearing, and base plate.
(FR)La présente invention concerne un moteur à axe comprenant un circuit de décharge électrostatique (ESD) permettant de décharger vers l'extérieur en toute sécurité les charges électriques introduites dans un arbre rotatif par une source extérieure, par l'intermédiaire d'une plaque de base, dans une structure comprenant un corps de palier fait d'une résine, ladite plaque de base étant moulée par insertion. Ledit moteur à axe comprend : un rotor présentant un centre auquel est accouplée une extrémité d'un arbre rotatif ; un palier qui supporte l'arbre rotatif de telle façon que ledit arbre rotatif puisse tourner ; un corps de palier présentant une rainure dans laquelle est accueilli le palier, et qui est fait d'une résine ; et une plaque de base dont la périphérie intérieure est encastrée dans le corps de palier. Une partie de la plaque de base entre en contact avec le palier de telle façon que l'électricité statique introduit par la source externe puisse être déchargée vers l'extérieur à travers l'arbre rotatif, le palier et la plaque de base.
(KO)본 발명은 수지를 사용하여 베어링 하우징을 형성함과 동시에 베이스 플레이트를 인서트 몰딩한 구조에서, 외부에서 회전축으로 유입된 전하를 베이스 플레이트를 통하여 외부로 안전하게 배출할 수 있는 정전기 방전(ESD) 경로를 구비한 스핀들 모터에 관한 것이다. 상기 본 발명은 중앙부에 회전축의 일단이 결합된 로터, 상기 회전축을 회전 가능하게 지지하는 베어링, 요홈 내부에 상기 베어링을 수용하며 수지로 이루어진 베어링 하우징, 및 내주부가 상기 베어링 하우징의 내부에 매입 결합되는 베이스 플레이트를 포함하며, 상기 베이스 플레이트는 일부가 상기 베어링과 접촉하여 외부에서 유입되는 정전기를 상기 회전축, 베어링 및 베이스 플레이트를 거쳐 외부로 배출하는 것을 특징으로 한다.
