Abstract

We designed new magnetic position sensor that consisted soft magnetic material, permanent magnet, and magnetic sensor. Our simulation showed that the sensor was sensitive to a particular manufacturing tolerance. We redesigned sensor structure to improve linearity of output and to scale back the influence of manufacturing tolerance. Therefore, our simulation showed that the sensor had high-linearity output and high-robustness for manufacturing tolerance.
