Abstract
For electric micromobility applications, an axial-length shortening is required for the coil winding area of the distributed winding stator. In addition, an integrated motor drive (IMD) system is desirable to achieve miniaturization, unitization, and improved efficiency of the motor drive systems. In this study, a new IMD system is proposed in which the coil-end of the distributed winding stator is replaced with a printed circuit board (PCB) and the drive circuit is integrated in that area. First, the proposed motor structure and prototype have been revealed. At the current stage, the coil-end PCB and the drive circuit PCB have been designed to be the same for integration, but they are separate boards. The drive characteristics of each individual component were evaluated and have been clarified. Additionally, the evaluation results of system efficiency and losses when these components are placed in spatial proximity have been presented.Keywords
