  • Optimized thermal system for an electric motor
    Patent number: 6787949
    Abstract: The cooling of an electric motor is optimized by the housing of the motor being provided with inlet vent holes that are positioned and sized to increase a total air flow rate through the housing interior and by the interior surface of the housing being shaped to conform to the stator winding end turns of the motor to direct a flow of cooling air around a greater surface area of the winding end turns before being exhausted through outlet vent holes of the housing.
    Type: Grant
    Filed: August 5, 2002
    Date of Patent: September 7, 2004
    Assignee: Emerson Electric Co.
    Inventors: Peter K. Bostwick, Daniel E. Bailey, Nathan C. Owen, Philip S. Johnson, Barry M. Newberg
  • Fluid management system for a housing of an electrical device
    Patent number: 6720693
    Abstract: A fluid management system provided on a housing of an electrical device includes a shelf that covers over electrical connections projecting from the housing and includes an annular flange and an annular diverging portion of the housing exterior surface that direct liquid by gravitation away from the electrical connectors projecting from the housing and away from the vent openings of the housing.
