Abstract
A rotary encoder may include a magnetic encoder disc having a plurality of magnetic features added to the disc by additive manufacturing distributed over a surface of the encoder disc, wherein the disc is configured for attachment to the end of a rotatable shaft, or a cylindrical metallic encoding feature having a plurality of magnetic features added to the cylindrical encoder by additive manufacturing distributed over the surface of the cylindrical encoding feature, wherein the encoding feature is capable of attachment to an outer diameter of the rotatable shaft. The encoder additionally includes a magnetic sensor positioned adjacent to the end of the rotatable shaft to detect magnetic signals from the magnetic features on the disc and/or positioned over the surface of the rotatable shaft to detect magnetic signals from the magnetic features on the encoding feature.
