The main classifications of motors are:
1, hydraulic motor: customarily refers to the output of rotary motion, the hydraulic pump provides hydraulic energy into mechanical energy energy conversion device.
2, high-speed motor: gear motor has a small size, light weight, simple structure, good workmanship, insensitive to the contamination of the oil, shock resistance and small inertia.
3, blade motor; is the rotor groove of the blade and the shell (stator ring) contact, in the inflow of liquid under the action of the rotor rotation of the hydraulic motor.
4, radial piston motor: has good reverse characteristics, so that the motor operation is absolutely quiet, suitable for servo system.
5, axial piston motor: is a kind of axis with rolling bearing support flow type cycloid hydraulic motor.
6, low-speed hydraulic motor: simple structure, reliable, many varieties and specifications, low price.
7, axial piston motor: a kind of axial flow with rolling bearing support cycloid hydraulic motor.

Basic composition of the motor:
This component consists of an internal gear ring and a gear or rotor with which it is matched. The inner gear ring is fixedly connected to the housing, and the oil entering through the oil port pushes the rotor to rotate around a center point. This slowly rotating rotor through the spline shaft drive output becomes a pendulum hydraulic motor.
After the introduction of this original cycloid motor, another concept of motor began to take shape over the decades of evolution. These motors had rollers mounted in a built-in gear ring. Motors with rollers provided high starting and running torque, and the rollers reduced friction, thus increasing efficiency and producing a stable output from the output shaft even at very low speeds.
The motor is rapidly reversed by changing the direction of the input and output flows and produces equal values of torque in both directions. The motors in each series are available in a variety of displacement options to meet a wide range of speed and torque requirements.
