Design Optimization of a Position Sensor for Linearity Range Extension

Popis výsledku v původním jazyce

This paper presents a magnetic design-optimized model of a linear variable differential transformer sensor with short coils and long armatures. The sensor has one excitation coil and two antiserially connected pickup coils located between two parallel armatures’ plates. A developed 3D analytical method and the finite element method are used for magnetic analysis and design optimization of a linear variable differential transformer sensor. The structure of the armatures is optimized to enhance the linearity range of the linear variable differential transformer sensor. The rectangular shape of the armature has been changed to a trapezoidal shape to decrease the nonlinearity error and extend the linearity range. The measured nonlinearity error is as low as 1.0% for the ±90 mm movement range.
