Abstract
永磁同步電機（PMSM）擁有較高的功率密度及工作效率，在運轉時啟動力矩大且噪音小等優點，近年來快速發展在無人機，風力發電及電動車等需高可靠度等應用上。然而，PMSM所普遍使用的銣鐵硼磁鐵，卻會受到溫度、震動及外加磁場等影響，導致磁石破裂或磁力退化等無法回復的傷害。因此本文提出以量測電壓電流訊號的方式進行磁通狀態估測，以期達到非侵入式，即時健康度診斷的效果。
Permanent Magnetic Synchronous Motor (PMSM) is a highly applicable machine in electric vehicles or wind generators, which features high power density, good efficiency and reliability. However, the performance of NdFeB Magnet in PMSM can be damaged due to environment factor such as heat, vibration and external magnetic field. The magnet thus may suffer from rupture or irreversible demagnetization. In this paper, we purpose a new detecting method based on non-invasive measurement of voltage and current signal to establish a flux estimator, which can work for real time rotor health evaluation.
