Abstract
A Halbach-based magnetic position sensor includes a Halbach magnetic element having a spatially rotating magnetization pattern along an extent, producing a focused and augmented magnetic field on a working side relative to a magnetic field on a non-working side. A sensing element on the working side is co-configured with the Halbach magnetic element for relative motion therebetween. The sensing element includes encoder circuitry and magnetic sensors that sense the working-side magnetic field and produce corresponding sensor signals. The encoder circuitry translates the sensor signals into position signals indicating relative position between the sensing element and the Halbach magnetic element. In one example the Halbach magnetic element has a closed curve (e.g., substantially circular or ring-like) configuration.
