Abstract: A bearing assembly cooperates with a bearing seat formed in a bearing housing and includes a bearing having an inner ring, an outer ring and a rolling element in engagement with the rings and an anti-rotation device. The anti-rotation device engages the outer ring to the bearing housing limiting rotation of the outer ring within the bearing seat. The anti-rotation device includes a first feature engaging the outer ring and a second feature engaging the bearing housing. The features limit the rotation of the outer ring within the bearing seat. The first feature has an internal surface for engagement the outer ring and the second feature includes an engagement surface for engaging a protrusion extending from the bearing housing.

Abstract: In one embodiment, a permanent magnet rotor is provided. The permanent magnet rotor includes a substantially cylindrical rotor core including an outer edge, an inner edge, and opposed first and second ends. The rotor further includes a first wall and a second wall defining at least one radial aperture extending radially through the rotor core. The rotor further includes at least one permanent magnet positioned within the at least one radial aperture. A first indentation is formed in one of the at least one permanent magnet and the first wall, the first indentation defining a first space between the at least one permanent magnet and the radial aperture first wall. The rotor further includes a first material positioned within the first space, the material configured to substantially prevent movement of the permanent magnet relative to the at least one radial aperture.
