液压马达和液压泵在工作原理上互逆的，当向泵输入压力油时，其轴输出转速和转矩就成为马达。但由于二者任务和要求有所不同，故在实际结构上也存在区别。
1.液压马达一般需要正反转，所以在内部结构上应具有对称性，而液压泵一般是单方向旋转的，没有这一要求。
In order to reduce oil suction resistance and longitudinal force, the size of the oil suction port of a hydraulic pump is generally larger than that of the oil outlet, and the pressure in the low-pressure chamber of the hydraulic motor is slightly higher than atmospheric pressure, so there is no such requirement
3.液压马达要求能在很宽的转速范围内正常工作，因此，应采用液动轴承或静压轴承。因为当马达速速很低时，若采用懂亚洲城，就不易形成润滑油膜。
4. The blade pump relies on the centrifugal force generated by the high-speed rotation of the blades along with the rotor to keep the blades tightly attached to the inner surface of the stator, which seals the oil and forms a working volume. If it is used as a motor, springs must be installed at the root of the hydraulic motor blades to ensure safety
证叶片始终贴紧定子内表面，以便马达能正常启动。
5. Hydraulic pumps need to ensure self-priming ability in their structure, while commercial motors do not have this requirement
6.液压马达必须具有较大的启动扭矩。所谓启动扭矩，就是马达由静止状态启动时，马达轴上所能输出的扭矩，该扭矩通常大于在同一工作压差时处于运行状态下的扭矩，所以，为了使启动扭矩尽可能接近工作状态下的扭矩，要求马达扭矩的脉动小，内部摩擦小
由于液压马达与液压泵具有上述不同的特点，使得很多类型的液压马达和液压泵不能互逆使用。
