Variable Reluctance resolver as a shaft position detection unit has been wildly used in harsh environments because of high reliability. This paper uses the finite element method to analyze the influence of the harmonic components in the magnetic field on the accuracy of the resolver, and proposes a method to add slots at stator combined with optimizing the output winding distributions to reduce the harmonic content in the output voltage. Finally, the sinusoidal of output voltage turned out to be improved and the resolver met the measurement accuracy of ±30’.
