A dynamoelectric machine or electric motor construction is disclosed in which the motor has a cylindrical shell having a stator core press-fitted therein and positioned axially with respect to the shell at a predetermined position. The stator core has a central bore which rotatably receives a rotor assembly, the latter having a rotor shaft extending outwardly from each end thereof. An end shield is press-fitted into each end of the cylindrical shell to a predetermined axial position thereby to support bearings journaling the rotor shaft, with the rotor shaft extending axially outwardly through one of the end shields for connection to its application. This one end shield has a seal which is maintained in perpendicular relation to the rotor shaft and which slidingly seals the interior of the motor relative to the end shield and to the rotary application and rotor shaft. The end shields have outer circular flanges which fit in face-to-face engagement with the inner surfaces of the cylindrical housing and which are bonded thereto for sealingly securing the end shields in position with respect to the housing. The housing has an outwardly extending flange at at least one thereof permitting the motor to be mounted to its application.
