A Configuration of Wound Mover Linear Resolver for Compensating Edge Effect

Resolvers are essential position sensors used for determining rotational and linear motion. However, in linear resolvers, longitudinal and lateral end effects reduce positioning accuracy, posing a significant challenge. To mitigate these effects, implementing compensation methods is crucial. One effective approach involves using a tubular structure instead of a flat structure. The tubular design eliminates the lateral end effect, also known as the edge effect, leading to improved accuracy and performance. This paper proposes a tubular structure for a wound mover resolver to address these challenges. The proposed design minimizes the impact of end effects and enhances sensor precision. To validate its performance, finite element simulations and experimental tests were conducted. The results confirm the effectiveness of the tubular resolver design, demonstrating improved accuracy and reduced positioning errors compared to conventional flat structures. These findings highlight the advantages of the tubular structure, making it a promising solution for high-accuracy resolver applications.
