    摘要: An electric motor-driven compressor includes a housing assembly comprising a motor housing and a compressor housing mounted thereto. The compressor housing contains a centrifugal compressor wheel that is mounted on a shaft of the motor rotor and also defines an air inlet that leads air into the compressor wheel, and a volute that collects the compressed air. Air bearings rotatably support the shaft. Cooling air passages are defined in the housing assembly for supplying cooling air to the air bearings. A diffuser between the exit of the compressor wheel and the volute serves to diffuse the compressed air. The compressor includes a heat shield formed separately from the compressor housing and the motor housing and disposed between them. The heat shield defines one wall of the diffuser and also cooperates with the housing assembly to define part of the cooling air passages for the cooling air supplied to the bearings.

    摘要: An electric motor-driven compressor having an electrical terminal block assembly and corresponding method of assembly are provided. The electrical terminal block assembly includes a base plate that has a staging feature for receiving a lug end of a motor stator cable prior to connection of the motor stator cable with a terminal bar of the terminal block assembly. In this way, once the terminal block assembly is lowered into the enclosure and the motor stator cable is no longer visible to the user, a stator cable fastener may be passed through a stator cable mounting hole in the terminal bar to engage the stator cable lug that is being held in the proper position by the staging feature of the base plate. Upon rotation of the stator cable fastener, the stator cable lug may be drawn into conductive engagement with the terminal bar.

    摘要: An air bearing assembly is provided that includes a bearing sleeve that has two slots side-by-side having rectangular profiles for engaging the ends of first and second bearing foils for supporting a shaft of a dual-stage compressor. The first rectangular-profile slot, which may be made using a broaching process, is designed to receive first ends of the first bearing foil and the second bearing foil. The second rectangular-profile slot, which may also be made using a broaching process, is designed to receive a second end of the second bearing foil. This dual-slot design replaces the complex “L” shaped single slot design of conventional bearing sleeves, allowing for high-volume, low-cost manufacturing of the bearing sleeves. The dual-slot design also provides for robust engagement of the bearing foils with the bearing sleeves, while allowing easy assembly and installation of the air bearing assemblies.

    摘要: A mechanism for differential pressure sealing for use in a compressor, such as for fuel cell applications, is described. In a dual-stage compressor, a low pressure side and/or a high pressure side of the dual-stage compressor may include a compressor wheel supported by a shaft that can rotate about an axis of the shaft. A seal carrier may be provided that rotates with the compressor wheel and includes a groove for receiving a sealing ring, which may be a split expansion ring. A static seal plate may be positioned around a periphery of a portion of the seal carrier, such that the sealing ring can seal against a contact surface of the static seal plate when received in the groove in order to create a pressure differential seal. The low pressure side may include one sealing ring, whereas the high pressure side may include two sealing rings positioned in series.
