Abstract: A compressor including a housing, a shaft configured to be rotated relative to the housing to compress a refrigerant, a motor configured to drive the shaft, a lubrication system configured to supply lubricant to the compressor, and a bearing configured to support the shaft. The shaft includes a wear-resistant sleeve-like treatment on at least a portion of an outer surface of the shaft adjacent the bearing. The lubricant is a lubricant blend composition that includes two or more lubricants, the two or more lubricants including a first lubricant and a second lubricant. The first lubricant is present at a higher volume percentage than the second lubricant, and the first lubricant includes a higher viscosity than the second lubricant.

Abstract: Disclosed are an electric motor and a simplified variable speed drive system which renders the use of filtering components in a motor drive circuit unnecessary and increases torque transfer from permanent magnets of the rotor to the output shaft. The motor includes a fluid gap between the rotor and the stator configured to receive a cooling fluid, such a refrigerant. A plurality of radially-abutting, bread loaf-shaped magnets having a flat base are respectively fixed to a plurality of longitudinally oriented mounting facets provided on the shaft to provide maximum torque transfer from the magnets to the shaft. An eddy shield disposed between the faceted shaft and the magnets thermally shunts high frequency harmonics from the magnets to the shaft and cooling fluid. The rotor components are mechanically secured by a sleeve disposed around the rotor.

Abstract: Permanent magnet rotors for electric motors, particularly electric motors for use in compressors, improve the electromagnetic efficiency of the motor. The rotors can include retention of surface permanent magnets using one or more of retaining features on the motor and/or pole spacers interfacing with corresponding features on a rotor core, the use of a monolithic magnet in the rotor, and/or use of a carbon fiber sleeve. The rotor can include an eddy current shield, disposed on the rotor core, on a surface of the rotor, or located within a sleeve surrounding the rotor. The rotor can be sized such that an air-gap between the rotor and a stator of a motor using the rotor is a predetermined amount that reduces electromagnetic losses such as eddy current losses.

Abstract: A variable orifice flow device controls the flow of refrigerant into a compressor motor housing in a compressor. The variable orifice flow device may include, for example, an electronic expansion valve, a thermal expansion valve, or a shuttling valve controlling the flow of refrigerant into a compressor motor housing. One or more flows of refrigerant may be through a fixed orifice, a valve seat of the variable orifice flow device, or leakage through a seal of the compressor motor housing, providing a baseline refrigerant flow to the inside of the compressor motor housing in addition to the flow through the variable orifice flow device.
