Abstract
A hermetic compressor assembly is disclosed including a motor compressor disposed within a hermetically sealed housing, wherein the housing has an oil sump in the bottom thereof from which oil is drawn to lubricate the compressor mechanism. An electric drive motor includes a vertical rotor having a lower axial end ring with rotor counterweight die cast therein, whereby turbulence and resulting agitation of the oil in the oil sump is prevented during rotation of the rotor. By die casting the counterweight within the end ring additional attachment parts and manufacturing steps are eliminated.
