1. A compressor comprising a frame, a rotor assembly, and a heat sink assembly, wherein the rotor assembly comprises a shaft to which an impeller, a bearing assembly and a rotor core are secured, wherein the bearing assembly comprises a pair of bearings, wherein the heat sink assembly comprises a sleeve, a first heat sink, and a second heat sink, wherein the first and second heat sinks are located at opposite ends of the sleeve, wherein the heat sink assembly comprises a heat sink that is disc shaped, and wherein the heat sink is located beneath the impeller and has a diameter greater than that of the impeller. 2. The compressor of claim 1, wherein the heat sink assembly comprises a heat sink having a plurality of legs, each leg extending radially from the sleeve. 3. The compressor of claim 2, wherein the legs are spaced evenly around the sleeve. 4. The compressor of claim 2, wherein the width of each leg tapers in a direction away from the sleeve. 5. The compressor of claim 1, wherein the heat sink projects into the underside of the impeller. 6. The compressor of claim 1, wherein the frame comprises an aperture having a diameter greater than that of the impeller and smaller than that of the heat sink, the rotor assembly extends through the aperture, and the heat sink is secured to the frame at the aperture. 7. The compressor of claim 1, wherein the first heat sink is proximal the impeller and is disc shaped. 8. The compressor of claim 1, wherein the second heat sink is proximal the rotor core and comprises a plurality of legs, each leg extending radially from the sleeve. 9. A compressor comprising a frame, a rotor assembly, and a heat sink assembly, wherein the rotor assembly comprises a shaft to which an impeller, a bearing assembly and a rotor core are secured, wherein the heat sink assembly is secured to the bearing assembly and comprises a heat sink, wherein the heat sink comprises a plurality of legs that extend radially outward, wherein each of the legs is secured to the frame, wherein a width of one or more of the plurality of legs tapers in a direction away from the sleeve, and wherein each of the legs is secured to the frame by an adhesive. 10. The compressor of claim 9, wherein the legs are spaced evenly around the sleeve. 11. A compressor comprising a frame, a rotor assembly, and a heat sink assembly, wherein the rotor assembly comprises a shaft to which an impeller, a bearing assembly and a rotor core are secured, the bearing assembly comprised a pair of bearings, the heat sink assembly comprises a sleeve to which a first heat sink and a second heat sink are secured, the first and second heat sinks are located at opposite ends of the sleeve, the sleeve is secured to the bearings, each of the heat sinks is secured to the frame, the first heat sink is proximal the impeller and is disc shaped, and the second heat sink is proximal the rotor core and comprises a plurality of legs that extend radially from the sleeve, wherein the heat sink projects into the underside of the impeller. 12. The compressor of claim 11, wherein the heat sink is located beneath the impeller and has a diameter greater than that of the impeller. 13. The compressor of claim 11, wherein the legs are spaced evenly around the sleeve. 14. The compressor of claim 11, wherein the width of each leg tapers in a direction away from the sleeve.
