Abstract
Damping mechanisms and motor assemblies are provided. In an embodiment, by way of example only, a damping mechanism includes an end cap, a bearing retainer plate, a bearing damper ring, a bearing assembly, and first and second lateral dampers. The bearing damper ring is disposed in an annular cavity inwardly from an inner diameter surface of the end cap and has a radially inwardly-extending flange. The bearing assembly is disposed in the annular cavity radially inwardly relative to the bearing damper ring. The first lateral damper is disposed between a radially inwardly-extending wall of the end cap and the bearing damper ring. The second lateral damper is disposed between the bearing damper ring and the bearing retainer plate.
