AI Technical Summary
Technical Problem
During the drop test of the air conditioner splitter, a large impact force was generated between the rotor and the stator of the outer rotor motor, resulting in bearing damage and noise.
Method used
An elastomer is provided between the bearing of the motor and the stator assembly, providing axial preload and retaining a compressible height to cushion the impact force.
Benefits of technology
Reduces the impact force between the bearing and the stator assembly when the motor falls, avoids bearing damage and reduces noise.

Abstract
A motor, a fan assembly, and a heating, ventilation and air conditioning device. The motor comprises a rotor assembly (11), a stator assembly (12), at least one bearing (13), and at least one elastic body (14). The bearing (13) is connected to the rotor assembly (11) and a relative position therebetween is fixed. The elastic body is disposed between the bearing (13) and the stator assembly (12), serving to maintain the bearing (13) at the stator assembly (12) with a certain axial preloading force while reserving a certain compressible height.
