1769-OF4CI 1.在區間(a)，磁極傳感器Ha和Hc檢測到N極并輸出信號。在這種情況下，如果晶體管 Tru+ 和 Trv= 導通，則電流從定子中的 U 相線圈流向 V 相線圈。此時，V相在轉子磁鐵中的北極被磁化(勵磁)，吸引南極，排斥北極。U 相在南極磁化(勵磁)并排斥轉子磁體中的南極。這導致轉子順時針旋轉。

2.在區間(b)中，超過60°，只有磁極傳感器Ha檢測到北極并輸出信號。在這種情況下，如果晶體管Tru+和Trw-導通，則電流從定子中的U相線圈流向W相線圈。U 相保持勵磁，吸引轉子磁體中的北極，并排斥轉子磁體中的南極。W 相被激發為北極并排斥轉子磁體中的北極。這導致轉子順時針旋轉。

3. 每旋轉60°，磁極傳感器Ha、Hb、Hc的ON/OFF組合發生變化。對于電機旋轉一圈，有6種不同的磁極傳感器輸出組合，分別用(a)到(f)表示。通過為每個模式順序切換一組確定的激發相，連續產生旋轉磁場。

另外，通過改變磁極傳感器Ha、Hb、Hc的各輸出組合的電流流過線圈的方式，可以反轉電動機的旋轉方向。

例如，如果僅磁極傳感器Ha檢測到N極并在上述間隔(b)輸出信號時晶體管Trv+和Tru-導通，則電流從V相線圈流向U相線圈定子。此時U相在轉子磁鐵中被勵磁為北極，吸引南極，排斥北極。V 相被激發為南極并排斥轉子磁體中的南極。這導致轉子逆時針旋轉。
