Research on the Computational Algorithms for Layer Wound Linear Variable Differential Transformers

Abstract

According to the algorithms of traditional Linear Variable Differential Transformers (LVDTs) could not represent the performances of the Layer Wound Linear Variable Differential Transformers (Layer Wound LVDTs), new computational algorithms were presented in this paper. Based on magnetic circuit theory, the calculations for the Layer Wound LVDT’s magnetic circuit reluctance, self-inductance, mutual inductance, output voltage and sensitivity are provided. Simulation analysis and experimental tests were used to verify the calculations. The results show that the calculations and equations can accurately express the performance of the Layer Wound LVDTs.
