Stator tooth segmentation and back-iron segmentation is key solution to easing the burden of manufacturing process of permanent magnet synchronous motor. The purpose of this paper is the design and characteristic analysis of permanent magnet synchronous motor having the segmented phase modular stators. Using by two-dimensional finite element method, the static/no-load characteristic analysis of the permanent magnet synchronous motor is performed. The analysis has been performed considering the additional air gaps between stator modules. The analysis results were experimentally verified, and the validity of the proposed analysis method and feasibility of the machine was confirmed.
