This paper proposes an improved analytical method to calculate the armature-reaction magnetic field (ARMF) of interior permanent magnet motors. Based on the winding function, the armature-reaction magnetic motive force is divided into the d-axis component and the q-axis component to facilitate the analysis. Considering the flux paths, the difference of rotor magnetic potentials in the d-axis and the q-axis is illustrated, which improves the accuracy of the ARMF calculation. The validity of the analytical technique is verified by the 2-D finite-element analysis.
