This paper deals with leakage flux calculation of a DC micromotor using hybrid finite element method with infinite element. The two-dimensional finite element method is applied to the analysis domain and the hybrid finite element method with infinite element is applied to the infinite domain. The use of the hybrid finite element method with infinite element makes it possible to reduce the domain to be analyzed and also does not increase the bandwidth of the system matrix. The leakage flux from the exterior region of the yoke and the usefulness of the shield case of the DC micromotor is shown. The results show that the increase of the depth of yoke and shield case can reduce the leakage flux. The quantitative influence on the leakage flux of the reluctivity of yoke and shield case is examined.
