節能減碳是目前國際相當關注的議題，為了能更好的管理工廠用電，經濟部也推動工廠取得ISO 50001能源管理系統認證，讓能源能得到更好的掌控。其中馬達轉動設備是現代化工廠中不可或缺的存在，用電佔比高達了70%左右，馬達的用電也成為管控的重要一環，尤其預防轉動設備異常故障時所連帶影響的停工損失更是重要。既然要能預防馬達損壞，又要能監控馬達的能耗，因此，本研究結合馬達電流特徵分析與能源績效分析，進行永磁同步馬達的三種傳動元件的電流訊號式異常診斷，並比較健康齒輪、輕微損壞、嚴重損壞以及潤滑油缺失的能源績效。根據量測到的驅動端與負載端數據顯示，嚴重異常與潤滑油缺失在電流式分析可以觀察到異常特徵，同時也可以發現嚴重異常時會額外耗能1.5%，以及潤滑油缺失時會額外耗能4.5%。齒輪在輕微異常時雖可以在電流頻譜上看到異常特徵，但是能源績效上卻難以判斷。此外在皮帶與鏈輪的分析上，異常特徵與能源績效是無法做出明確判斷。

nergy conservation and carbon reduction is a topic of considerable international concern at present. In order to better manage the power consumption of factories, the Ministry of Economic Affairs has also promoted factories to obtain ISO 50001 energy management system certification, so that energy can be better controlled. Among them, motor rotating equipment is an indispensable existence in modern factories, and the proportion of electricity consumption is as high as 70%. Electricity consumption of motors has also become an important part of control, especially to prevent the loss of downtime caused by abnormal failure of rotating equipment. more important. Since it is necessary to prevent motor damage and monitor the energy consumption of the motor, this study proposes to combine the current signal analysis and energy performance analysis to carry out abnormal diagnosis and energy consumption analysis of permanent magnet synchronous motor with three transmission components, and analyze the energy consumption of the motor. The abnormal analysis results of the current signal analysis are combined with the energy consumption analysis results. Compare gears for healthy, minor damage, severe damage, and lack of lubricant. Use MCSA and energy performance analysis based on the measured drive-side and load-side data. Serious anomalies and lack of lubricating oil can see abnormal characteristics in the amperometric analysis, and it can also be seen that an additional 1.5% of energy is consumed in severe anomalies, and an additional 4.5% of energy is consumed when lubricating oil is missing. When the gear is slightly abnormal, abnormal characteristics can be seen in the MCSA, but it is difficult to judge the energy performance. In the analysis of belts and sprockets, abnormal characteristics and energy performance cannot be judged.
