Abstract: A dynamoelectric machine has a housing with generally axially extending radially spaced apart inner and outer circumferential surfaces with a generally annular external rabbet in said outer circumferential surface. An end frame is arranged in a preselected assembly position on the housing and has a generally annular internal rabbet received generally in mating engagement about the external rabbet when the end frame is in its preselected assembly position.

Abstract: A base assembly for mounting a dynamo-electric machine on a planar mounting surface includes a generally rectangular metal sheet with flat foot portions and a cradle portion intermediate the foot portions. Leg portions of the metal sheet each incline upwardly from a corresponding foot portion to support the cradle portion a first preset height above the mounting surface. The foot portions are capable being drawn to increase the height of the cradle portion above the mounting surface to a second preset height, so that the axis of a rotor shaft of a motor supported by the base assembly will extend over the mounting surface at an increased height. The base assembly can also be detachably fixed to the machine shell by welding through selected mounting holes provided in the cradle portion, such that the welds can be released with a milling tool.
