Abstract
Abstract A bearing retaining unitary plastic end plate for a dynamoelectric machine is disclosed. The end plate includes a through passage for receipt of the normally provided armature bearing and armature bearing retaining means. In order to accommodate placement of the dynamoelectric machine so that the axis of rotation of the armature may be at or near the vertical, the through passage is provided with a discontinuous ridge for receipt of resilient fingers extending from the bearing retaining means. This ridge is formed by providing a plurality of passages extending part-way through the end plate structure parallel to the axis of the through passage and intersecting the through passage in the vicinity of bearing retaining means. The end plate structure is also formed with a pair of molded, opposed wire retaining clip members for receiving any internal wiring and preventing that wiring from entering the brush/commutator interface. A resilient clip means is provided for mounting the end plate structure on the housing of the dynamoelectric machine while providing central support for the end plate.
