An orbital motor, also known as a hydraulic orbital motor, is a hydraulic motor that converts hydraulic energy into mechanical energy. It works on the principle of orbiting motion. The motor consists of an inner rotor and an outer stator. The inner rotor has a series of lobes, while the outer stator has a corresponding series of curved slots. The lobes and slots are arranged in such a way that the rotor is held in position by the stator, but is still able to rotate.
When hydraulic fluid is supplied to the motor, it enters through the inlet port and flows into the motor chamber. The fluid then flows into the rotor, which is forced to rotate due to the pressure of the fluid. As the rotor rotates, the lobes push against the stator, causing the stator to move in an orbiting motion. This motion is transferred to the output shaft, which then rotates at the same speed as the rotor.
The working principle of an orbital motor is based on the principle of displacement. This means that the amount of fluid that enters the motor chamber is equal to the amount of fluid that is displaced by the rotor. This displacement is what causes the rotor to rotate and the output shaft to move. The displacement is determined by the size of the rotor and the number of lobes it has.
Orbital motors are widely used in a variety of applications, including agricultural machinery, construction equipment, mining equipment, and marine equipment. They are preferred over other types of hydraulic motors because of their high efficiency, low noise, and compact size. They are also easy to maintain and repair.
In conclusion, the working principle of an orbital motor is based on the principle of orbiting motion and displacement. It converts hydraulic energy into mechanical energy and is widely used in various applications. Its efficiency, low noise, and compact size make it a preferred choice for many industries.
