  • Swtiching phase offset for contactor optimization
    Patent number: 9899173
    Abstract: A system and methods providing for minimizing the arc energy delivered to the pads of a plurality of contactors using a single control coil based on monitoring the electrical sine waves of the three alternating current electrical poles and calculating the instant to energize or deenergize a single control coil. The remainder of the contactors will make or break based on an offset in time from the making or breaking of the control contactor.
    Type: Grant
    Filed: February 10, 2017
    Date of Patent: February 20, 2018
    Assignee: ROCKWELL AUTOMATION TECHNOLOGIES, INC.
    Inventors: Hans Weichert, James Peter Miller, Urs Hunziker, Reynald Kaltenrieder, Lorenz Laeuppi
