ABSTRACT:
A frameless motor includes a laminated annular stator core having an internal bore and a winding projecting from the ends. The bore is enlarged in the end laminations with an annular diameter precisely defining the bearing axis. Cup-shaped bearing supports have precisely formed ends complementing the enlarged bore with an axially spaced bearing wall. the rotor is supported in the bearing supports to support and align the rotor with an air gap to create a complete and framelss dynamoelectric machine which can subsequently be assembled to any suitable support or housing. A cup-shaped cylindrical housing with the outer end machined to a stepped recess has an internal diameter substantially corresponding to the inner bore of the stator core and an outer nominal diameter complementing the internal enlarged bore. Alternatively, the cup-shaped bearing support is formed with a cylindrical housing having an end flange which is precisely machined to the bearing opening and the enlarged bore.
