图4-4(a)是单叶片摆动马达若从油口Ⅰ通入高压油，叶片2作逆时针摆动，低压力从油口Ⅱ排出由于叶片与输出轴相连，帮助输出轴摆动输出扭矩，克服负载 此类摆动马达的工作压力小于10MPa，摆动角度小于280°。
由于径向力不平衡，叶片和壳体、叶片和挡块之间密封困难，限制了其工作压力的进一步提高，从而也限制了输出转矩的进一步提高 摆动缸液压电机工作原理 图4-4(b)是双叶片式摆动马达在径向尺寸和工作压力相同的情况下，单片摆动电机的输出转矩是单片摆动电机的两倍，但旋转角度应相应减小。
双片摆动电机的旋转角度一般小于120° 叶片摆动电机的总效率η=对于单叶摆动电机，70%~95% 设其机械效率为1，出口背压为零，则它的输出转矩： 式中：P为单叶片摆动马达的进口压力；B为叶片宽度；R1为叶片轴外半径，叶片内半径；R2为叶片外半径。
