Hydraulic Motor

From the point of view of energy conversion, hydraulic pumps and hydraulic motors are reversible work of hydraulic components, input of liquid to any kind of hydraulic pumps, hydraulic motor can make it into working condition; otherwise, when driven by an external torque hydraulic motor spindle rotates, but also into a hydraulic pump condition. Because they have the same basic structural elements-closed and periodic changes in the volume and the corresponding allocation of oil bodies.

However, because of different working conditions of hydraulic motors and hydraulic pumps, on their performance requirements are not the same, so between the same types of hydraulic motors and hydraulic pumps, there are still many differences. First hydraulic motor should be able to forward and reverse, which requires its internal structure of symmetric hydraulic motor speed range needs to be big enough, especially for its minimum stable speed has certain requirements. Therefore, it usually uses rolling bearings or bearings with all second hydraulic motor due to working in oil input pressure conditions, so you don't have to have the ability to suck, but need some initial sealing, can provide the necessary starting torque. Because of these differences, hydraulic motors and hydraulic pumps is similar in structure, but not invertible.
