Abstract:
    This invention relates to a control method and a system for non-round winding speed of molded rolled cores of transmission and distribution appliances, in which, the method includes: 1, setting up an angular velocity math model for a non-round winded transformer, 2, providing a constant strain angular speed based on a constant line speed, the system includes: an unreeling motor, winded core, an upper roller above the winded core, an angular detector at either end of the winded core and a reeling motor and a motor rotation controller connecting the angular detector and the reeling motor, in which, the controller receives an angular velocity W providing constant speed winding strain got by constant line speed drive to drive the winded motor to rotate.
