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，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，定子對柱塞的反作用力為 。力可分解為和 兩個分力。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，力對缸體產(chǎn)生一轉(zhuǎn)矩，使缸體旋轉(zhuǎn)。缸體再通過端面連接的傳動軸向外輸出轉(zhuǎn)矩和轉(zhuǎn)速。以析的一個柱塞產(chǎn)生轉(zhuǎn)矩的情況，由于在壓油區(qū)作用有好幾個柱塞，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。
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，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，柱塞在壓力油作用下外伸，緊貼斜盤，斜盤對柱塞產(chǎn)生一個法向反力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則使柱塞對缸體中心產(chǎn)生一個轉(zhuǎn)矩，帶動馬達(dá)軸逆時針方向旋轉(zhuǎn)。軸向柱塞馬達(dá)產(chǎn)生的瞬時總轉(zhuǎn)矩是脈動的。若改變馬達(dá)壓力油輸入方向，則馬達(dá)軸按順時針方向旋轉(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
