Why is orbital hydraulic motor called ORBITAL ?

In the late 1850s, the original low-speed high torque hydraulic motor was developed from a stator and rotor component of the oil pump.

This part consists of an inner ring gear and a matching gear or rotor. The inner gear ring is fixedly connected with the housing, and the oil entering from the oil port pushes the rotor to rotate around a central point. This kind of slowly rotating rotor drives output through spline shaft and becomes orbital hydraulic motor. After the first orbital motor came out, after decades of evolution, Fei Yue hydraulic motor delivers high-efficiency hydraulic energy for you. Another concept of the motor began to take shape, This kind of motor is equipped with rollers in the built-in gear ring.

The motor with roller can provide high starting and running torque. The roller reduces friction and improves efficiency. Even at very low speed, the output shaft can produce stable output. By changing the direction of the input and output flow, the motor quickly reverses and produces equal torque in both directions. Each series of motors have a variety of displacement options to meet the requirements of various speeds and torques. Orbital oil motor is a kind of small, low speed, high torque hydraulic motor with internal orbital gear. Its structure is simple, low-speed performance is good, short-term overload capacity is strong. The orbital motor has a stator and a movable blade.

The stator, blade and drive shaft divide the motor into two cavities. Each cavity has an oil port. When one port enters oil, the other gives out oil. The oil inlet cavity pushes the blade to swing.
