1. A compressor comprising:
a compression mechanism configured to compress a fluid from a suction pressure to a discharge pressure;
a driveshaft engaged with the compression mechanism and fixed to rotate with at least a portion of the compression mechanism;
a motor configured to rotate the driveshaft; and
a shell assembly defining a suction chamber, wherein the compression mechanism, the driveshaft, and the motor are disposed within the shell assembly, and wherein the fluid at the suction pressure in the suction chamber circulates through the motor and is configured to transfer heat away from the motor,
wherein the driveshaft includes a longitudinal aperture configured to receive the fluid at the suction pressure, and
the driveshaft includes a flange that receives at least a portion of the compression mechanism, the flange and the compression mechanism defining a fluid passage therebetween, the fluid at the suction pressure being received within the fluid passage from the longitudinal aperture in the driveshaft.
