Title (EN) BASE UNIT AND OPTICAL DISC DEVICE
(FR) UNITÉ DE BASE ET DISPOSITIF À DISQUE OPTIQUE
(JA) ベースユニット及び光ディスク装置
Abstract:
(EN) This base unit is provided with: a base unit chassis that supports a spindle motor; a heat dissipating member that dissipates heat to a base unit chassis side, on which a disc is not mounted, said heat having been generated from a stator of the spindle motor; and a means for suppressing heat transfer from a stator core to a bearing of the spindle motor.
(FR) L'invention concerne unité de base qui est pourvue : d'un châssis d'unité de base qui prend en charge un moteur à broche; d'un élément de dissipation de chaleur qui dissipe la chaleur vers un côté de châssis d'unité de base, sur lequel un disque n'est pas monté, ladite chaleur ayant été générée à partir d'un stator du moteur à broche; et un moyen pour supprimer le transfert de chaleur d'un noyau de stator à un palier du moteur à broche.
(JA) スピンドルモータを支持するベースユニットシャーシと、スピンドルモータのステータから発生する熱をベースユニットシャーシの非ディスク装着側へ放熱する放熱部材と、ステータコアからスピンドルモータの軸受への熱伝達を抑制する手段とを備えたベースユニットである。
