1. An end cap assembly for attenuating electrical noise of an electrical motor having a shaft and a housing case, the assembly comprising:

  • a conductive panel having inner and outer surfaces and including interconnecting and/or non-interconnecting conductive members;

    an attenuating circuit including a number of discrete electrical components supported at the inner surface of the conductive panel and electrically connected by the conductive members;

    terminals connected to and extending away from the outer surface of the conductive panel to facilitate connection of the end cap assembly in an electrical system;

    an electrically insulating end cap housing for housing the conductive panel and the plurality of discrete electrical components, wherein the conductive panel and the plurality of discrete electrical components attenuate conductive electrical noise and wherein the conductive panel functions as a radiated field transmission shield; and

    a bearing assembly supported by the conductive panel for, in turn, rotatably supporting the shaft of the motor within the assembly.
