  • Patent number: 8492943
    Abstract: A motor includes a stator core and windings extending through the stator core. The windings include end turns extending from the stator core that form a coil. A protector is electrically connected to the windings and is positioned adjacent the coil. A bracket is sized and shaped to receive the protector, and includes a spacer in contact with the protector and with the coil. The protector is spaced from the coil by the spacer to reduce heat transfer from the windings to the protector.
    Type: Grant

    Date of Patent: July 23, 2013
    Assignee: Emerson Electric Co.
    Inventors: Vincent P. Fargo, J. Scott Rose, Donald R. Shaw, Dick Cao, Xilai Yang, Cedar Liu
  • Patent number: 8485789
    Abstract: A system and method for modulating capacity of a scroll compressor having a motor includes determining a target capacity of the scroll compressor, operating the motor at a first speed when the target capacity is within a first predetermined capacity range and at a second speed when the target capacity is within a second predetermined capacity range, determining a pulse width modulation cyclic ratio based on the target capacity and the first or second speed, and periodically separating intermeshing scroll members of the compressor according to the pulse width modulation cyclic ratio to modulate the capacity of the scroll compressor.
