Abstract
An end bell for a motor has a base plate, a bearing and a molded insert to couple the bearing to the base plate. The end bell with molded insert is durable, light weight and has good anti-corrosion properties. The bearing is held in relation to the base plate while the molded insert is disposed. A post-mold machining operation can be used to both size the bearing hole to the motor shaft but also to align the hole in relation to the base plate. Bushings and fasteners for assembly of the end bell to the motor housing and supplemental supports may be pre-attached to the base plate, molded into the molded insert or added in a post-mold operation. Deformations in the end bell may be used to couple the molded insert to the end bell.
