Abstract
A motor assembly, such as an evaporator fan for a refrigerator, has a motor, first and second mounting bracket segments, and monolithic and elastomeric first and second grommets. The motor housing has opposingly protruding first and second end bosses. Each grommet includes inner and outer ring portions joined together by spaced-apart and generally-radially-extending spoke portions. The inner ring portion is positioned on the corresponding end boss. The outer ring portion has a hub and a circumferential flange radially projecting form the hub. Each mounting bracket segment has an opening, wherein the hub is positioned in the corresponding opening and wherein the circumferential flange longitudinally abuts the corresponding mounting bracket segment.
