在工業4.0及工業自動化備受提倡之後，電機的使用逐年成長，電機驅動器(Motor Driver)的需求也隨之上升，一般市售電機皆需搭配符合其規格之驅動器。在電機應用中，大量使用的風機因各種因素損壞或更換設置地點時，需更換不同功率的風機，都需要將驅動器拆下進行維護或更換，尤其在風機密集的廠房內，更換的時間成本及費用將會是一大問題。因此本研究基於風機常用之三相直流無刷電機(Three-phase Brushed DC motor, BDCM)設計出一驅動電路能夠應用於多功率範圍的電機，除了能夠減少電機損壞時更換的時間之外，在因應更換不同功率的電機時，也能夠判別合適該電機之操作範圍進行運作，不須特別經過手動調整或更換，改善長久以來必須將電機與驅動器同步拆換的技術與成本問題，能夠大量減少檢修人力與更換需求。
本文對於風機常用之三相直流無刷電機驅動器提出一種新的多功率電機驅動器設計，透過數位訊號處理器(Digital Signal Processor, DSP)提供的訊號與程式的判別進行軟體架構的設計，利用三相變頻器(Three-phase Inverter)開關切換訊號進行設計，選用空間向量脈波寬度調變(Space Vector Pulse Width Modulation, SVPWM)為本研究之控制策略，並採用霍爾感測器(Hall Sensor)訊號進行轉子位置回授，提供回授轉速以利轉速閉迴路的設計，針對各功率電機以不同轉速運行時的參數與波形進行驗證與分析，最後將判別結果以淺顯易懂的燈號顯示。整體系統研發實作結果，驗證本文所提出的三相直流無刷馬達驅動電路應用於多功率風機馬達之研究達成預期設立之目標，對於未來智慧型驅控系統的研究，提供了新的可行方案及持續發展方向。

After Industry 4.0 and industrial automation have been advocated, the use of electric motors has been growing year by year, and the demand for motor drivers has also increased.In motor applications, a large number of fans used due to various factors damage or change the location of the installation, the need to replace the fan of different power, it is necessary to remove the driver for maintenance or replacement, especially in the fan dense factory, the time cost and cost of replacement will be a major problem. Therefore, this study is based on the three-phase Brushless DC motor (BLDC) commonly used in wind turbines to design a driver that can be applied to a wide range of multi-power motors, in addition to reducing the time to replace the motor when it is damaged, in response to the replacement of different power motors, it can also be judged suitable for the operation of the motor range, without the need for special manual adjustment or replacement.This will improve the technical and cost problems that have long been associated with the simultaneous disassembly and replacement of motors and drives, and will greatly reduce the need for inspection and replacement.
In this paper, we propose a new multi-power motor drive design for a three-phase BLDC driver commonly used in wind turbines, using a digital signal processor (DSP) to provide the signal and program discrimination for the software architecture design, and a three-phase inverter switching signal for the design. The design is based on the space vector pulse width modulation (SVPWM) control strategy, and the Hall sensor signal is used for rotor position feedback to provide the feedback speed for the closed loop design. The system is designed to verify and analyze the parameters and waveforms of each power motor at different speeds, and finally display the results with easy-to-understand LED signals. The results of the overall system research and development have verified that the proposed three-phase BLDC drive circuit for multi-power motors has achieved the expected objectives, and has provided a new feasible solution and continuous development direction for future research on intelligent drive control systems.
