Abstract
A motor assembly has a stator and rotor housed within a frame. An end shield is attached to one end of the frame for rotatably supporting a shaft extending therethrough. A fan is mounted to the shaft adjacent the end shield. A fan cover is mounted to the end shield and about the fan in a snap-fit manner. The end shield includes a front face and an annular side face, and has a plurality of slots formed in the annular face. The end shield also includes a boss adjacent each slot, which is formed to include at least one bearing surface and a ramp thereon. The fan cover includes a plurality of mounting brackets spaced about its inner periphery and extending outwardly toward the end shield. Each mounting bracket has a projection thereon, which is receivable within the slot on the annular face of the end shield. Each bracket also includes a backstop with a crushable rib thereon. As the projection is received in the slot, the bearing surface of the boss contacts and deforms the crushable rib on the backstop, thus ensuring a tight, snap-fit between the fan cover and the end shield.
