This paper proposes a general design method of modular multiphase permanent-magnet synchronous machine with hybrid single/double layer (HL) fractional-slot concentrated winding (FSCW), which indicates that double-layer (DL) FSCW machines satisfying two preconditions can be transformed into HL FSCW machines. HL FSCW machines with diff erent slot and pole number combination are designed to prove the feasibility and universality of the proposed method. Performance of single-layer (SL) FSCW machine, DL FSCW machine, and HL FSCW machine are compared, from aspects of magnetomotive force, back electromotive force, average torque, torque ripple, core loss, eddy current loss in PMs (PM loss), effi ciency, cogging torque, and fl ux density distribution. Besides, phase-to-phase magnetic isolation of HL FSCW machine, indicating by fl ux lines distributions and phase-to-phase mutual inductances, is also researched. HL FSCW machine has advantages of higher torque, lower PM loss, higher effi ciency, better phase-to-phase thermal, physical and magnetic isolation compared with SL FSCW machine and DL FSCW machine.

본 발명품은 Arduino UNO를 사용하여 설계한 바텐딩 제어 시스템을 채용한 것으로서 주요 기능은 전자밸브와 펌프의 공동 작동을 통해 모든 음료의 토핑 재료를 정확하게 추출하여 혼합하여 생산하며, 수출 상단에는 LED와 음향을 장착하여 시각 및 청각 효과를 더욱 좋게 하였으며, 바텐더의 도움 없이도 가정에서 사용할 수 있다. With the development of intelligent electronic technology, newly smart machine technology comes true. This paper mainly use Arduino UNO to design a control system of the current blender, the main function of the system is to accurately control the ingredient of each drink through the peristaltic pump control circuit and relay circuit, the wine is modulated by the mixing mechanism, For better visual and acoustic effects, LED and sound are added above the reclaiming port. Through the order system to select drinks without the intervention of the staff, the equipment is in the state of no sales.

With the development of power industry, communication security has become an important issue affecting the stability of power system. IEC 62351 standard provides security for substation communication system. However, different transmission protocols may lead to different manufacturers to produce different understanding, manufacturing is not compatible with the device. In order to avoid such a situation, the Finite State Machine (FSM) theory is used to model and analyze the transmission protocol of IEC 62351 standard. In this paper, the FSM model is simulated by the StateFlow tool, and it can be considered that the FSM theory is applicable to the analysis of compliance with IEC 62351 standard.
