Dynamoelectric machine

Claim 1

A dynamoelectric machine adapted for energization comprising: a housing having a horizontal centerline axis with an imaginary plane passing therethrough to define a vertical axis of the dynamoelectric machine, said housing including generally axially extending radially spaced apart first inner and outer circumferential surfaces generally coaxial with the horizontal centerline axis, at least one end face extending generally radially between said first inner and outer circumferential surfaces, and at least one circumferential external rabbet in said first outer circumferential surface having a generally annular first base wall intersecting said at least one end face and a generally annular first sidewall intersecting said first base wall and said first outer circumferential surface; a stator assembly disposed within said first inner circumferential surface and axially spaced from said at least one end face, said stator assembly including winding means for excitation upon the energization of the dynamoelectric machine; rotatable means extending generally coaxially through said stator assembly for magnetic coupling relation with said winding means upon the excitation thereof; at least one end frame means disposed in a preselected assembly position on said housing for rotatably supporting a part of said rotatable means, said at least one end frame means including generally axially extending radially spaced apart second inner and outer circumferential surfaces, another end face extending generally radially between said second inner and outer circumferential surfaces, a circumferential internal rabbet in said second inner circumferential surface having a generally annular second base wall intersecting said another end face and a generally annular second sidewall intersecting said second base wall and said second inner circumferential surface, said second base wall being received in engagement about said first base wall, said another end face being disposed in facing relation at least adjacent said first sidewall and said second sidewall being disposed in facing relation at least adjacent said at least one end face when said at least one end frame means is in its preselected assembly position on said housing, four flanges integral with said second outer circumferential surface and extending generally radially therefrom, and each flanges having an aperture therein with a centerline axis radially spaced about the horizontal centerline axis generally about thirty seven and one half degrees (37° 30') from the vertical axis when said at least one end frame is in the preselected assembly position thereof; said housing further including another four flanges integral with said first outer circumferential surface, said another four flanges each having a threaded aperture coaxial with another centerline axis and each another centerline axis being radially spaced about the horizontal centerline axis generally about thirty seven and one half degrees (37° 30') from the vertical axis so as to generally axially align with a respective one of said first named apertures when said at least one end frame means is in its preselected assembly position; a pair of mounting pads integrally formed with two adjacent ones of said another four flanges and extending therefrom generally in oppositely spaced relation with the vertical axis, respectively, each mounting pad including a part blended in shape with one of said two adjacent ones of said another four flanges, a free end part, and at least one opening spaced between said blended part and said free end part with said at least one opening having a third centerline axis arranged generally in predetermined spaced parallel relation with the vertical axis so as to intersect with said first outer circumferential surface; and a set of means extending at least in part through said first named and threaded apertures for threaded interconnection with said threaded apertures, respectively, to releasably maintain said at least one end frame against displacement from its preselected assembly position.
