A transcritical vapor compression system includes a compressor assembly that includes an oil separator for separating oil from refrigerant. The oil separator is disposed between a motor and a compression chamber in a sub-critical portion of the vapor compression system. Oil emitted from the drive assembly attached to the motor is substantially removed from the refrigerant before entering the compression chamber of the compressor.
