Design of a linear rotary transformer/digital conversion circuit

Abstract: Linear rotary transformers are widely used in solving quantities and high-precision servo systems due to their high precision and strong anti-interference ability. There are many technical solutions for realizing linear resolver solving circuit. This paper elaborates a conversion circuit design method based on DDC RD-19230 as the core chip, focusing on the design process and verifying the accuracy of the design method through experiments. .

Keywords: linear rotary transformer, RD-19230, shaft angle converter.
