本研究在開發應用於高能效冷凝風機系統中的無感測永磁同步馬達及其驅動器。研究的核心技術包括無感測器控制策略和驅動器的結構設計，意在提升系統的整體能效和性能。我們採用了三相全橋整流器的架構，以實現對馬達的精確控制。此外，採用滑模觀測器（Sliding Mode Observer, SMO）來實現無感測的轉子位置估計，進一步透過磁場導向控制（Field-Oriented Control, FOC）來精準調節轉矩電流和磁通電流。驅動系統整合了空間向量脈波寬度調變（Space Vector Pulse Width Modulation, SVPWM）技術，以優化功率元件開關動作，減少驅動器的熱損失並提高效率。通過一系列的動力測試，本研究不僅確認了驅動系統在不同負載條件下的高效能，還展示了其在不同操作條件下的穩定性和可靠性。實驗結果表明，所開發的驅動系統在標準操作條件下的效率可達90%以上，整體效率也有75%以上。綜上所述，本文探討了無感測永磁同步馬達及其驅動器在高能效冷凝風機系統中的應用潛力，為未來節能型高效應用提供了一個實用且高效的解決方案。此項技術的實施有望在工業及商業環境中推廣，實現能效提升與運營成本降低。

The objective of this paper is to develop sensorless permanent magnet synchronous motors and their drives for application in energy-efficient condensing fan systems. The core technologies investigated include sensorless control strategy and structural design of the drive, which are intended to improve the overall energy efficiency and performance of the system. A three-phase full-bridge rectifier architecture is adopted to achieve precise control of the motor. In addition, a Sliding Mode Observer (SMO) is used for sensorless rotor position estimation, and Field- Oriented Control (FOC) is used to precisely regulate the torque current and flux current. The drive system integrates Space Vector Pulse Width Modulation (SVPWM) technology to optimize the switching action of power components, reduce the thermal loss of the drive and improve the efficiency. Through a series of dynamic tests, this study not only confirms the high performance of the drive system under different loading conditions, but also demonstrates its stability and reliability under different operating conditions. The experimental results show that the developed drive system can achieve an efficiency of over 90% under standard operating conditions and an overall efficiency of over 75%. In summary, this paper explores the potential application of sensorless permanent magnet synchronous motors and their drives in energy-efficient condensing fan systems, providing a practical and efficient solution for future energy-saving high-efficiency applications. The implementation of this technology is expected to be replicated in industrial and commercial environments, realizing energy efficiency gains and operating cost reductions.
