ABSTRACT:
An electric motor comprising a shell supporting a stator and end members rotatably supporting a rotor. The end members are fastened to the shell in a manner such that the end members are accurately positioned longitudinally of the shell and the center of the end member is accurately positioned relative to the axis of the shell. One end member includes an annular portion spaced from the periphery which extends axially outwardly, and a radially axially extending portion that extends axially inwardly. An annular bearing seat is fixed thereto and a roller bearing is interposed between the bearing seat and the shaft. The other end member is provided with an annular wall spaced from the periphery, and a radial wall which supports a self-aligning bearing. An external oil catcher cover frictionally engages the annular wall of one end member and extends radially inwardly into overlying relation with the self-aligning bearing. An external oil catcher cover frictionally engages the first annular portion of the other end member and extending radially inwardly into generally overlying relationship to the roller bearing.
