軸向柱塞泵除閥式配流外，其它形式原則上都可以作為液壓馬達(dá)用，即軸向柱塞泵和軸向柱塞馬達(dá)是可逆的。軸向柱塞馬達(dá)的工作原理為，配油盤和斜盤固定不動(dòng)，馬達(dá)軸與缸體相連接一起旋轉(zhuǎn)。當(dāng)壓力油經(jīng)配油盤的窗口進(jìn)入缸體的柱塞孔時(shí)，柱塞在壓力油作用下外伸，緊貼斜盤，斜盤對(duì)柱塞產(chǎn)生一個(gè)法向反力p，此力可分解為軸向分力及和垂直分力Q。Q與柱塞上液壓力相平衡，而Q則使柱塞對(duì)缸體中心產(chǎn)生一個(gè)轉(zhuǎn)矩，帶動(dòng)馬達(dá)軸逆時(shí)針方向旋轉(zhuǎn)。軸向柱塞馬達(dá)產(chǎn)生的瞬時(shí)總轉(zhuǎn)矩是脈動(dòng)的。若改變馬達(dá)壓力油輸入方向，則馬達(dá)軸按順時(shí)針方向旋轉(zhuǎn)。斜盤傾角a的改變、即排量的變化，不僅影響馬達(dá)的轉(zhuǎn)矩，而且影響它的轉(zhuǎn)速和轉(zhuǎn)向。斜盤傾角越大，產(chǎn)生轉(zhuǎn)矩越大，轉(zhuǎn)速越低。軸向柱塞泵 E-A4VSO250EO2/30R-VPB25N00-SO3

工作原理，當(dāng)壓力油經(jīng)固定的配油軸4的窗口進(jìn)入缸體內(nèi)柱塞的底部時(shí)，柱塞向外伸出，緊緊頂住定子的內(nèi)壁，由于定子與缸體存在一偏心距。在柱塞與定子接觸處，定子對(duì)柱塞的反作用力為 。力可分解為和 兩個(gè)分力。當(dāng)作用在柱塞底部的油液壓力為p，柱塞直徑為d，力和之間的夾角為X時(shí)，力對(duì)缸體產(chǎn)生一轉(zhuǎn)矩，使缸體旋轉(zhuǎn)。缸體再通過端面連接的傳動(dòng)軸向外輸出轉(zhuǎn)矩和轉(zhuǎn)速。以析的一個(gè)柱塞產(chǎn)生轉(zhuǎn)矩的情況，由于在壓油區(qū)作用有好幾個(gè)柱塞，在這些柱塞上所產(chǎn)生的轉(zhuǎn)矩都使缸體旋轉(zhuǎn)，并輸出轉(zhuǎn)矩。徑向柱塞液壓馬達(dá)多用于低速大轉(zhuǎn)矩的情況下。E-A4VS0180DR/30R-PPB13N00

折疊低速馬達(dá)
轉(zhuǎn)速低于500r/min的液壓馬達(dá)屬于低速液壓馬達(dá)。它的基本形式是徑向柱塞式。低速液壓馬達(dá)的主要特點(diǎn)是:排量大，體積大，轉(zhuǎn)速低，可以直接與工作機(jī)構(gòu)連接，不需要減速裝置，使傳動(dòng)機(jī)構(gòu)大大簡化，低速液壓馬達(dá)的輸出扭矩較大，可達(dá)幾千到幾萬Nm，因此又稱為低速大扭矩液壓馬達(dá)。
