無論為FOC選擇的是有傳感器還是無傳感器的實現方式，都準確測量相電流以保持的扭矩控制。測量相電流的常用方法是在逆變器級中使用分流電阻器在每個低側 MOSFET 的源極和地之間進行低側檢測。由于分流器的共模電壓降低，可使用低成本電流檢測放大器。高側（串聯(lián)）相電流檢測通常需要昂貴的專業(yè)的高共模抑制比CMRR或隔離放大器電路來減輕共模電壓誤差，因為共模電壓在PWM頻率下大致在直流輸入電壓和地之間波動。

理想情況下，所有三個相位的電流都是同時測量的，但有可能減少分流電阻器的數量，從而降低系統(tǒng)成本和功率損耗，但會增加電流檢測帶寬和軟件復雜性。雙分流架構依靠基爾霍夫電流定律（Kirchhoff’s current law），從兩個測量電流計算未測量電流（例如，流入 U 和 V 相的電流等于流出 W 相的電流）。單分流器架構需要了解逆變器開關狀態(tài)才能將測量電流與實際相電流相關聯(lián)。通常，用于確定所有相電流的測量精度會隨著分流電阻數量的減少（從 3 個減少到 1個）而降低。因此，需要更快的測量電路，并且總系統(tǒng)延遲成為一個更重要的因素。此外，在跟蹤檢測的正確時刻和確定從測量電流到實際相電流的相關性方面，軟件的復雜性也會增加，在單分流架構中為明顯。
