Abstract
A motor assembly includes a first bearing installed on a rotating shaft adjacent to an impeller to support a first support part of the rotating shaft, a second bearing installed on the rotating shaft adjacent to the rotor to support a second support part of the rotating shaft, a bearing bracket receiving the first and second bearings therein, an elastic member inserted between the first bearing and the bearing bracket or between the second bearing and the bearing bracket to press either the first bearing or the second bearing to get closer to each other, and a separation preventing member installed on the bearing bracket to fix the first bearing, the second bearing and the elastic member to an inner space of the bearing bracket such that at least one portion of the separation preventing member overlaps with one of the first bearing, the second bearing and the elastic member.
