Abstract
(EN)
One embodiment of this bearing holder is provided in a motor which has a rotor which rotates around a center axis, a stator which faces the rotor in the radial direction and a housing for holding the stator, said bearing holder being configured so as to support the rotor so as to be capable of rotating relative to the stator with bearings interposed therebetween. The bearing holder has a resin section for holding the bearings which comprise a resin, and a busbar to which a lead wire extending from the coil of the stator is connected. The busbar is embedded in the resin section.

Un mode de réalisation de la présente invention concerne un support de palier prévu dans un moteur qui a un rotor qui tourne autour d'un axe central, un stator qui fait face au rotor dans la direction radiale et un boîtier pour maintenir le stator, ledit support de palier étant conçu de manière à supporter le rotor de manière à pouvoir tourner par rapport au stator avec des paliers interposés entre eux. Le support de palier a une section de résine pour maintenir les paliers qui comprennent une résine, et une barre omnibus à laquelle un fil conducteur s'étendant à partir de la bobine du stator est connecté. La barre omnibus est incorporée dans la section de résine.
