圖4-4(a)是單葉片擺動馬達若從油口Ⅰ通入高壓油，葉片2作逆時針擺動，低壓力從油口Ⅱ排出由于葉片與輸出軸相連，幫助輸出軸擺動輸出扭矩，克服負載 此類擺動馬達的工作壓力小于10MPa，擺動角度小于280°。
由于徑向力不平衡，葉片和殼體、葉片和擋塊之間密封困難，限制了其工作壓力的進一步提高，從而也限制了輸出轉矩的進一步提高 擺動缸液壓電機工作原理 圖4-4(b)是雙葉片式擺動馬達在徑向尺寸和工作壓力相同的情況下，單片擺動電機的輸出轉矩是單片擺動電機的兩倍，但旋轉角度應相應減小。
雙片擺動電機的旋轉角度一般小于120° 葉片擺動電機的總效率η=對于單葉擺動電機，70%~95% 設其機械效率為1，出口背壓為零，則它的輸出轉矩： 式中：P為單葉片擺動馬達的進口壓力；B為葉片寬度；R1為葉片軸外半徑，葉片內半徑；R2為葉片外半徑。
