Classification of motors

Hydraulic motor: Traditionally refers to the output of rotary motion, the hydraulic pump provided by the energy conversion device into mechanical energy.

High speed motor: gear motor has the advantages of small size, light weight, simple structure, good technology, insensitive to oil pollution, impact resistance and small inertia. Disadvantages include larger torque pulsation, lower efficiency, smaller starting torque and low speed stability.

Blade motor; It is a hydraulic motor in which the blade in the rotor groove is in contact with the shell and rotates the rotor under the action of the incoming liquid. Compared with other types of motors, the blade motor has the advantages of compact structure, smaller contour size, low noise, long life and so on. Its inertia is smaller than the plunger motor, but its anti-pollution ability is worse than that of the gear motor, and the speed can not be too high, and generally works below 200r/min. Because of the large leakage, the blade motor is unstable when the load changes or at low speed.

Radial piston motor: Good reverse characteristics, so that the motor operation is absolutely quiet, suitable for servo systems. Can be used as a motor or pump two-way operation.

Axial piston motor: It is a kind of axial distribution flow cycloidal hydraulic motor with rolling bearing support. It adopts the overall structure design of output shaft and distribution mechanism, inserts type fixed rotor, both ends of the rolling bearing support, special inlet back rotation sealing ring, so that the motor can work under high back pressure.

Low speed hydraulic motor: simple structure, reliable operation, variety specifications, low price. Its disadvantages are larger volume and weight, larger torque pulsation.

Axial piston motor: It is a kind of axial distribution flow cycloidal hydraulic motor with rolling bearing support. It adopts the overall structure design of output shaft and distribution mechanism, inserts type fixed rotor, both ends of the rolling bearing support, special inlet back rotation sealing ring, so that the motor can work under high back pressure.

Cycloidal motor: is a kind of internal engagement cycloidal gear type of small, low speed, large torque hydraulic motor. Its structure is simple, low speed performance is good, short - term overload capacity is strong. Cycloidal motor inside has a stator and an active blade, stator, blade and drive shaft motor into two cavities, each cavity has an oil port, when an oil inlet another oil, oil inlet to promote the blade swing.

Piston type air motor: It is a connecting rod, crankshaft, piston, cylinder, body, distribution valve and so on. Compressed air through the distribution valve, in turn to each cylinder gas supply, so as to expand work, through the connecting rod to drive the crankshaft rotation. The work mainly comes from gas expansion work.
