摘要： This invention relates to a method and apparatus for electronically gearing the sewing parts of a sewing machine, and more particularly it relates to electronically gearing the bobbin to the needle to eliminate the necessity of their physical coupling through mechanical linkages and drive shafts. Servo motors provide torque to the needle, bobbin, and various other sewing parts of the sewing machine which require concerted movement. A computer uses servo motor positional information to calculate motion commands that are sent to the needle and bobbin servo motors, thereby enabling electronic gearing of the bobbin to the needle so that each moves substantially in unison. Motion commands sent to servo motors attached to various other sewing parts of the sewing machine are based on servo motor positional information to enable the sewing parts to move in concert with the needle and bobbin. Servo motors move the sewing material in two dimensions during stitching, and each move of the sewing material is calculated to consume the maximum amount of time available between stitches in order to dampen acceleration and deceleration of sewing parts and eliminate problems associated with machine jerk.
