Oil retainer cooling assembly for an electric motor

A motor assembly comprising;

• a substantially tubular housing having a first end and a second end opposite of said first end disposed about a longitudinal axis;
• a motor shaft disposed in said housing along said longitudinal axis, wherein said motor shaft includes an output end extending from said first end of housing and a non-output end extending from said second end of housing in a direction opposite of said output end;
• a rotor assembly fixed onto said motor shaft within said housing;
• a bearing assembly engaged to said second end and having a bore co-axial with said motor shaft for supporting said non-output end for said motor shaft rotation, wherein said bearing assembly includes an oil lubricant;
• an oil retainer cooling assembly having a hub that includes a hub bore for the insertion and attachment of said hub to said motor shaft, and a plurality of fan blades protruding radially from said hub, whereby said oil retainer assembly rotates with said shaft causing said blades to induce air flow within said housing, thereby cooling said motor assembly.
