英文摘要：

This paper proposes a new type of axial flux reluctance resolver with distributed windings in order to re-duce the measurement errors, and elaborates its structural components. The corresponding analysis on its optimiza-tion is carried out to figure out the important structural parameters. The change rules of the function errors are de-rived through the magnetic circuit analysis for different teeth numbers, different poles and phases. The finite ele-ment analysis method is used to study the effects of the output electromotive forces of signal windings when the val-ues of air gap and pole pairs are changed. The analysis results show that different structural parameters can cause the changes in the amplitude of the output voltage and the function error. The optimization process can improve the measurement accuracy of the axial flux reluctance resolver with distributed windings. As a result, it provides a theo-retical basis for the fabrication of prototypes to some extent.
