永磁馬達在工業發展上佔據相當大成分的貢獻，不論在工業界亦或學術界都大量地使用永磁馬達做為動力來源，這顯現永磁馬達的檢驗相當重要，現行的檢驗方法早已不敷使用。本文秉持著工業4.0的精神，不再使用傳統的量測方式來進行生產線上的檢驗技術，透過永磁馬達系統模型的建立，提供一種生產線上永磁馬達全檢估測系統，可讓檢驗者快速求得馬達的反電動勢常數、轉矩常數、黏滯係數、轉子慣量以及馬達性曲線(T-N Curve)，藉此達到生產線上的馬達品質管制。
根據IEEE標準馬達特性加速度量測法，當馬達不外加慣量盤量測T-N曲線時，易受到電流暫態影響，嚴重降低馬達特性曲線量測的精準度，為了提升使用者的方便性及量測精準度，本文提出不需外接慣量盤的線上永磁馬達全檢估測系統，可快速獲得馬達檢測時所需的重要參數，並透過統計學上的GR&R分析，進而更能輕易地使用在生產線上、增加馬達生產的產能、提升馬達的良率以及減少馬達出廠之後失效的可能。
本文使用LabVIEW為介面，並以Maxwell電磁模擬軟體分析馬達無外加負載啟動的轉矩輸出曲線，進而提出新的轉矩估測方法，可以用在生產線上快速全檢、精準且低成本。

PM motors play a great role in the industrial applications because of their outstanding efficiency and convenience. However, the tremendous production activities cause the difficulty of checking the quality of all products in production lines. Concerning PM motors, the characteristic measurements of permanent magnet motors such as torque-speed, power, and efficiency are essential during manufacturing. Especially for the torque-speed curve, which normal measuring approach is time consuming and may not be easy to be applied on on-line product quality control. This paper presents a novel method for obtaining torque-speed curve, which is based on the previous self-developed method that can measure the moment of inertia without using external mechanical connection. That is to say, it is capable to rapidly retrieve the torque-speed characteristics of PM motors. This paper successfully resolves the incorrectness in measurement that is resulted from the inductance of coils prevent motor to output torque at each speed that PM motors may originally able to do on the dynamometer equipment. This approach enables the output torque of PM motors without any loading to perform the same with PM motors tested with dynamometer equipment.
