Abstract
A rotational resolver system and method includes a rotational shaft to which at least one eccentric conductive coarse resolution disc is fixed and to which at least one conductive fine resolution disc is also fixed. The fine resolution disc defines a plurality of generally semicircular protruding edge segments. At least one conductive coarse-disc sensing coil is disposed adjacent an edge of the coarse resolution disc, and at least one conductive fine-disc sensing coil is disposed adjacent the edge of the fine resolution disc. These coils may be oriented for axial sensing of the respective disc.
