Due to the above different characteristics of hydraulic motor and hydraulic pump, many types of hydraulic motor and hydraulic pump cannot be used together.

Hydraulic motors are divided into high speed and low speed according to their rated speed. High speed hydraulic motors are those whose rated speed exceeds 500r/min, and low speed hydraulic motors are those whose rated speed exceeds 500r/min.

The basic models of high-speed hydraulic motors include gear type, screw type, vane type and axial plunger type. Its main characteristics are high speed, small moment of inertia, convenient starting and braking, and high speed regulation and steering sensitivity. Generally, the output torque of high-speed hydraulic motor is not large (from dozens of Nm to hundreds of Nm), which is also called high-speed small torque hydraulic motor.

The basic model of high-speed hydraulic motor is radial plunger type, such as single acting crankshaft connecting rod type, hydraulic balance type and multi acting internal curve type. In addition, Hydraulic motor Axial plunger type, vane type and gear type also have low speed structure type. The main characteristics of low-speed hydraulic motor are large emissions, large volume and low speed (sometimes it can reach various times to zero), so Hydraulic motor of agricultural machinery It can be directly connected to the working mechanism without the need for a speed reducer, simplifying the transmission mechanism. Generally, the output torque of low-speed hydraulic motors is large (it can reach thousands of Newton meters to tens of thousands of Newton meters)

Hydraulic motor can also be divided into gear type, vane type, plunger type and other types according to its structure type.
