Industrial Hydraulic Motors

Hydraulic motors for mobile equipment are used in applications where rotational energy output is necessary. While it may sound like their use-cases are very straightforward, their execution is often widely varied and application-specific.

At Cross Mobile Systems Integration group, we work with you as an extension of your engineering team to make sure you have the right hydraulic motor and the optimal hydraulic motor system design.

When it comes to heavy industrial equipment, the design of the hydraulic motor system is one of the most important considerations. Whether it’s for construction or industrial mining, it’s critical to optimize your space, heat dissipation, and motor system design.

We’ve worked with countless OEMs and other equipment manufacturers to design, prototype, and implement full hydraulic systems. And we’re excited to work with you, too. If you’re looking for a hydraulic motor company who will work with you to create your optimal mobile machine, you’ve come to the right place.

Custom Hydraulic Motor Designs

Selecting the best hydraulic motor for your application can be a challenge. As multiple motor design options can work for a specific application, it’s important to choose the best hydraulic motor for the job to ensure the best performance of your machine.

Take a look at our Guide to Selecting The Right Hydraulic Motor for 17 important questions to ask when selecting a hydraulic motor.

The team at Cross has experience implementing a range of hydraulic motors into a variety of applications and our selection includes products from industry leading manufacturers, so you know you can trust your machine performance.

We offer a variety of pumps for OEM and other equipment manufacturers. This includes open loop gear pumps, open loop piston pumps, and open loop vane pumps.

Within an open loop hydraulic system, the actuator-return and inlet ports are both connected to the hydraulic reservoir. This allows the pump to provide continuous fluid power to the system. Because of this design, open loop systems are generally able to run cooler (as the reservoir lets more heat dissipate).

While an open loop hydraulic system may be more complex than its closed loop counterpart, they allow for a wider variance in system design. Furthermore, a higher level of control can be achieved through stacking multiple control valves in a series. This isn’t a functionality allowed for in closed loop hydraulic systems.

If you’re looking for pumps for an open loop hydraulic system, we can help. Contact our experts today to discuss your open loop hydraulic system or manufacturing process.

If your application requires a significant amount of power, a hydraulic piston motor may be the best option for your machine.

Hydraulic piston motors are frequently used to drive mobile industrial equipment. We’ve seen them used in construction, cranes, mining, and a variety of other applications across the industrial world.

A piston motor is best-suited for applications requiring low speed and high torque. This can be seen in their prevalence in applications such as earth-moving, mining, or agriculture. The wide-spread use of piston motors for industrial applications is a testament to their efficiency and ability to be successfully integrated into hydraulic systems.

Piston motors are a key component of many heavy mobile machines. Though specific hydraulic system requirements must be considered, such as range of load, serviceability, and space allocation.

Vane motors are drives that convert inflowing gas or liquid pressure into rotary motion. They are made up of a cartridge assembly of a motor housing. This makes their design very similar to a vane pump. They are also typically easier to configure and service, making them a high-efficiency solution for a wide variety of industries.

A vane motor is able to change the torque-to-speed ratio within having to shift the gears. This allows for the elimination of gear boxes or any external speed-reduction equipment. Vane motors also allow for different speed and torque combinations for a wide range of flow and pressure requirements.

These features make vane motors optimal for many industrial applications, especially ones that may have changing power or flow requirements. If this describes your mobile vehicle, then a vane motor may be optimal.

An orbital motor is made up of several roller vanes positioned around the inside diameter of a stator which behave as guides for an internal rotor’s orbit. This orbital rotation is achieved through pressure from the fluid flow.

An orbital motor typically has lower space requirements to implement, as they tend to be smaller in size and lighter in weight compared to many other industrial hydraulic motors with similar torque.

Orbital motors can also be used both in series or parallel within a hydraulic system. In many cases, they are able to be installed relatively easily with an intuitive layout and low initial cost. These features make them especially well-suited for many OEMs and other mobile machine manufacturers.

A radial piston motor is a drive that is able to convert the pressure from an inflowing gas or liquid into a rotary motion. This makes it suitable for mobile machine applications with high torque and low speed.

The motor function is achieved by utilizing five pistons within a cylinder block that is mounted on the driveshaft. Pressurized hydraulic fluid is fed to the pistons through fluid paths within the crankshaft.

Radial piston motors also function as a direct drive. That means they function as a low-speed, high-torque hydraulic motor that couples with the axis it’s moving. Due to this, there is no gearbox required.

Bent axle piston motors are known for being high-performance and high-efficiency at high operating pressures. Bent axis motors can be positioned (or “bent”) at angles of ~40° while having the benefit of a wider operating torque and speed range than an in-line motor of similar specifications.

Bent Axle motors were developed initially to improve the torque efficiencies of high-speed motors, both in operation and while stalled.

These motors are well-suited for many on and off-highway mobile applications, as well as a wide array of circuit types.

Hydraulic Motors For All Applications

To implement the best hydraulic motor possible, vehicle manufacturers need to take a number of factors into consideration. These could include the state of the relief valves, the size and condition of the hydraulic reservoir, as well as the number and condition of the hydraulic pumps.

You need a hydraulic motor company that can design, prototype, and implement a hydraulic motor to your specifications and the unique requirements of your industry.

When it comes to industry-specific hydraulic motor design and implementation, Cross can help. We’ve worked with manufacturers across countless industries. And we’re excited to work with you next.

Frequently Asked Questions

Selecting the right hydraulic motor is a necessary step of the process. It all begins with analyzing the performance needs of the machine. After that, the next steps involve working backward all the way to the pump. This allows us to optimize every part of the hydraulic system to find the best solution for you.

In terms of performance, the radial piston motor or axial piston motor tends to be the most efficient. They are typically rated at around 95% (for the radial piston motor) and 90% (for the axial piston motor). Generally, orbital or gear motors will have less upfront cost, but will be lower in levels of efficiency.

This often depends on the pressure of the system and the flow itself. But if the system pressure and flow are constant, then a standard equation can be used to determine optimal hydraulic motor sizing.
