在馬達的製程上，由於各種製造公差，例如磁鐵充磁、馬達組裝、定子繞線、甚至製程上若發生位置感測器產生平移或是旋轉的安裝誤差，均可能造成電流激磁角度誤差而導致馬達產品輸入功耗不一。本文針對電流激磁角度誤差而導致馬達產品的輸入功耗不一的現象研究解決方法，期望在無法改善製程設計的狀況下，利用永磁同步馬達位置感測器組裝誤差之電流激磁角校準策略之其演算法，將馬達的輸入功耗控制在最低點，並維持其原有的穩定輸出。本演算法以磁場導向控制(Field-Oriented Control , FOC)技術為基礎控制架構，因其控制法之電流漣波相較於其他方法較小，有利於演算法中之電流判別資訊，並以模擬與實驗驗證之。結果顯示本文所提出之永磁同步馬達位置感測器組裝誤差之電流激磁角校準策略，確實能在含有製程誤差造成的電流激磁誤差下，將馬達的輸入功耗最小化，並且在非線性負載的使用情況下依舊能使之維持預期的穩定輸出。

This thesis proposes a method to decrease the consumption of the input power by applying current angle calibration strategy. The major extra consumption of the input power comes from the position sensor mounting deviation of the permanent magnet synchronous motor, this results in inaccurate current excitation angle.
In order to solve this problem, this thesis analyses the influence of the position sensor mounting deviation on the motor output power, and proposes a new current angle calibration strategy for PMSM position sensor mounting deviation by combining the power disturbance method and automatic lead angle control.
The proposed method allows the motor to operate with the minimum required input power by controlling the current excitation angle. To validate the method, a series of experiments are conducted. The results confirmed that the proposed strategy can indeed decrease the input power consumption caused by the position sensor mounting deviation.
