    • A disk for an electric meter includes a solid annulus of a conductive material with a center of the annulus filled with a non-conducting material. The non-conducting material is preferably molded in place both to capture the annulus and to secure a disk shaft into a unitary assembly. The annulus distorts eddy currents at distances from sets of potential and current stators of the electric meter to minimize radial components of eddy currents in the vicinity of neighboring sets of potential and current stators. The reduced radial components of eddy currents reduces the constructive or destructive interaction of the eddy currents with their neighboring sources of flux. Increasing the angular separation of the sets of potential and current stators further reduces interaction.
    • 用于电表的盘包括具有填充有非导电材料的环形空间中心的导电材料的固体环形区域。 非导电材料优选地被模制在适当位置以捕获环空并将盘轴固定成单一组件。 环形区域在距离电表的电位和当前定子的距离之间扭曲涡流,以使邻近电位和当前定子附近的涡流的径向分量最小化。 涡流减小的径向分量减少了涡流与其相邻的磁通源的建构性或破坏性相互作用。 增加潜在和当前定子组的角度间隔进一步降低了相互作用。
