因?yàn)檩S向柱塞式液壓馬達(dá)具有很多以上的優(yōu)點(diǎn)，所以被廣泛地使用。缺點(diǎn)是這樣的液壓馬達(dá)即使在低速時(shí)輸出功率還較小，用于直接帶動(dòng)負(fù)載進(jìn)行低速運(yùn)轉(zhuǎn)的機(jī)器，例如起重運(yùn)輸機(jī)械、車輛行走機(jī)構(gòu)等。在啟動(dòng)和低速運(yùn)轉(zhuǎn)時(shí)，扭矩、功率常常不能滿足運(yùn)行要求。因此，經(jīng)常配備各種類型的減速裝置，從而帶來機(jī)器體積大的缺點(diǎn)。近年來，低速、大轉(zhuǎn)矩的液壓馬達(dá)得到了較大的發(fā)展，出現(xiàn)了很多新的結(jié)構(gòu)。此外，力士樂液壓馬達(dá)可以基于每旋轉(zhuǎn)一圈的中間柱塞副的操作數(shù)來分類為單作用類型或多作用類型。根據(jù)柱塞布置形式的不同，每種類型可分為徑向式柱塞布置和軸向式柱塞布置。徑向馬達(dá)根據(jù)其結(jié)構(gòu)特征和柱塞副的受力方式的不同，可以分為不同類型。

Because the axial piston hydraulic motor has many advantages above, it is widely used. The disadvantage is that the output power of such a hydraulic motor is still small even at low speed. It is used to directly drive the load to run at low speed, such as lifting and transportation machinery, vehicle traveling mechanism, etc. When starting and running at low speed, the torque and power often cannot meet the operating requirements. Therefore, it is often equipped with various types of reduction devices, which brings the disadvantage of large size of the machine. In recent years, hydraulic motors with low speed and high torque have been greatly developed, and many new structures have appeared. In addition, Rexroth hydraulic motors can be classified into single acting or multi acting types based on the number of operations of the intermediate plunger pair per revolution. According to the different arrangement forms of the plunger, each type can be divided into radial plunger arrangement and axial plunger arrangement. Radial motors can be divided into different types according to their structural characteristics and the force bearing mode of the plunger pair.
