CA 2327028
A combined bearing plate and stator frame for an air compressor powered by an electric motor, such air compressor having a crankshaft rotationally supported by a rotational bearing and such electric motor includes a rotor and a stator substantially surrounding such rotor, such rotor being mounted on a portion of such crankshaft for rotation therewith, the combined bearing plate and stator frame being adapted for integration into such air compressor so as to provide a bearing plate for mounting of such rotational bearing and a stator frame for mounting of such stator therein and aligning such stator with such rotor mounted on such portion of such crankshaft. The combined bearing plate and stator frame includes a bearing plate member and a stator frame member, such bearing plate member and such stator frame member being integrally formed from a single piece of material. The stator frame member includes a substantially bowl-shaped member, and the substantially bowl-shaped member includes a substantially closed wall portion. Such wall portion has a first substantially open end, and a second end is at least partially closed by an end wall. There is an aperture formed in such end wall of the substantially bowl- shaped member. Such bearing plate member includes a horseshoe-shaped portion at least partially encircling the aperture formed in the end wall, and a wedge-shaped portion extending outward from such horseshoe-shaped portion.
