Hydraulic Orbital Motors' Benefits Compared To Other Hydraulic Motor Designs

Even though hydraulic motors are a desirable solution for a wide variety of applications, a quick search reveals that there are a great deal of distinct types of hydraulic motors. One of the topics that will be covered in this blog post is the advantages that orbital motors have over other types of designs. In addition to this, applications for orbital motors will be presented, and examples of situations in which other designs might be more suitable will be emphasized.

Why Opt For Hydraulic Motors Instead Of Electric Motors?

Hydraulic pumps can be converted into motors that rotate hydraulic fluid flow in a method that is comparable to the way in which generators can be utilized to supply power to electric motors. When it is not possible to supply an electric motor with adequate current and voltage to assist the generation of the requisite torque and power, hydraulic motors are the most suitable alternative. This is because hydraulic motors are able to produce torque and power whereas electric motors cannot.

These motors are not only used extensively in mobile gear, but they are also used to power heavy-duty industrial equipment such as long conveyors, mixers, and molding machines. This is because of their versatility and versatility in supporting a wide range of applications. The elimination of a potential source of ignition is achieved by the avoidance of the usage of electricity, which makes this approach a suitable answer for circumstances in which there is a risk of explosion.

Hydraulic Motor Types

The primary means by which this is performed is through the usage of gear, vane, and piston systems in order to convert fluid flow into rotational motion.

A wide variety of hydraulic piston motors are available in a variety of different designs. A fluid applies force to a piston, which then operates on a shaft or, in certain situations, a swash plate that is attached to a shaft. This process is repeated until the piston works on the shaft. These techniques are all based on this fundamental idea, which is the foundation of all of them.

It is possible to draw parallels between vane motors and a traditional waterwheel from this perspective. When the vanes are arranged in a circular arrangement around the circumference of the wheel, they are positioned in such a way that their outer edge is flat with the housing. In the event that fluid is delivered through an input port and causes pressure to be exerted on the vanes, the wheel will turn.

There are two main types of gear motors: gerotor designs, which consist of a gear that is enclosed within another gear, and external gears, which are comparable to an oil pump that has a spur gear. Gerotor designs are the more common type of gear motor.

The rotation of the inner gear around the surface of the stationary outer gear is what distinguishes a gerotor from other types of gear boxes. The hydraulic orbital motor gets its name from the fluid pressure that rotates the inner gear, which eventually completes an orbit inside the stator. This eventually causes the inner gear to complete an orbit. The motor receives its name from this particular aspect. In order to deliver motion and torque, the mechanism that is responsible for doing so is the output shaft, which is attached to the rotor.

Important Features Of Hydraulic Orbital Motors  

As far as this particular configuration is concerned, the outer stator has one more tooth than the inner gear, which is also referred to as the rotor. When the rotor revolves around the stator at a rate that is larger than the orbit speed, a gear ratio is produced. This mechanism is responsible for the formation of gear ratios. Due to the fact that this reduction in speed has the effect of compounding torque, a hydraulic orbital motor has the capacity to generate a large amount of torque even while it is working at low speeds.

The dimensions of the thing are yet another characteristic that sets it apart. The compact design that is generated by inserting the rotor inside the stator results in a better power density when compared to other types of hydraulic motors. Another type of hydraulic motor is the rotor-driven motor. A measurement of the amount of torque that is produced at a given volume of the motor is referred to as the power density of the motor.

Hydraulic Orbital Motors: Advantages  

These motors are ideal for a wide range of applications due to a number of factors:

1. Power density is higher than in other designs

2. Greater torque

3. Low rate of output

4. Simpler to operate than piston motors

5. Longer lasting than vane motors

Hydraulic Orbital Motors' Limitations  

It is possible that a hydraulic orbital is not the best choice in certain situations, despite the fact that they are highly versatile and effective. Take, for example:

1. If the application required a high speed—more than 500–1,000 revolutions per minute—a hydraulic orbital motor would most certainly need some kind of speed-multiplying gearbox, which would add both money and complexity to the production process.

2. The lifespan of a hydraulic orbital motor can be extended in applications that need low torque by operating the motor at a level that is far lower than its rated output; however, alternative designs may be more cost-effective.

Excellent Uses For Hydraulic Orbital Motors

Because they have a high power density, these are the best option for wheel motors in machinery like skid steers. This is because they are the most suited choice. Furthermore, they are utilized extensively in mobile equipment for mining, forestry, construction, and agricultural uses. This utilizes them in a variety of applications.

Cost, performance, and durability are the characteristics that are more significant than space and motor size when it comes to stationary industrial applications. Space and motor size are of secondary importance. It is possible for a hydraulic orbital motor to eliminate the requirement for a speed-reducing transmission when it is operating at low speeds. This results in a large amount of time being saved. Another component that contributes to the lifespan and dependability of the product is the construction, which features a construction that is both sturdy and robust.

The Appropriate Hydraulic Motor For Your Use

There are three various types of hydraulic orbital motors that Impro Fluidtek manufactures. These motors are ideal for applications that require light-duty, medium-duty, and heavy-duty operations depending on their respective capacities. This is due to the fact that displacements, speeds, and torque all provide exceptional power density, low speed, and torque, which makes them the preferred solution in a variety of applications. The fact that each design is one of a kind does not change the reality that they all share certain features.We would be happy to review your application and provide you with additional information about it if you would want to do so.
