  • Method of manufacturing stator and rotor cores
    Patent number: 5915750
    Abstract: A tandem press system for the high speed manufacture of rotor cores and stator cores of electric motors. The tandem press system includes a rotor press and a stator press arranged in series for stamping out laminations from a web of stock material and pre-assembling them into rotor cores and stator cores, respectively. Structure is provided between the rotor and stator press to maintain control of the web and provide a substantial barrier to transmission of vibrations in the web to the stator press. The rotor and stator presses are capable of shifting from stamping one type of lamination to stamping another type of lamination without any interruption in the operation of the presses.
    Type: Grant
    Filed: February 19, 1997
    Date of Patent: June 29, 1999
    Assignee: General Electric Company
