Abstract: A dynamoelectric machine is provided with a frame structure consisting of at least two fabricated sheet metal pieces of identical shape and size. The sheet metal members are formed to provide cavities to accommodate an armature structure and bearings, and the opposed sheet metal pieces enclose and support the armature and bearing when fixed together. The sheet metal pieces also support preferably a ceramic magnet field by providing formed bosses and tabs for locating and holding the magnets in position. If additional low reluctance flux path is required, a tubular jacket may be placed over the sheet metal housing. The bearings are preferably spherical bearings, and the invention contemplates providing the sheet metal pieces with formed bearing retaining areas and having grooves to retain a fibrous lubricant containing material formed either in the retaining areas or the bearings or both.
