Radial Piston Motors

Radial piston motors with internal support are a special category of constant motors characterized by high torque at low speeds. These features make them ideal slow-running motors with smooth starting. A key feature of these motors is the ability to reverse the direction of rotation, allowing for versatile use.
The motors are compactly built, making them suitable for use in various industrial environments. Their high power density and robustness against shock loads increase their reliability and lifespan. These qualities make them a preferred choice in industrial hydraulics, such as in rubber, plastic, and paper manufacturing plants, as well as in recycling facilities. Additionally, radial piston motors with internal support are used in specialized fields such as mining, shipbuilding, and offshore applications. In the mobile sector, they stand out for their suitability as drivetrains that can be directly integrated into the wheel hubs of vehicles like forklifts, wheel loaders, road rollers, and street cleaning vehicles. This versatility and performance highlight their significance in a wide range of industrial and mobile applications.

As a partner of Italgroup, a renowned Italian manufacturer of radial piston motors, we offer products based on years of experience and expertise in developing and manufacturing these specialized motors. This partnership enables us to provide our customers with high-quality and powerful solutions for a variety of industrial and mobile applications.

Radial Piston Motor - Frequently Asked Questions

What is a radial piston motor and how does it work?

A radial piston motor is a hydraulic drive component that converts hydraulic pressure into mechanical energy. In this motor, pistons are arranged radially around a shaft. When hydraulic oil flows into the motor, the pistons move in a star pattern around the shaft, generating torque that is used to drive machines.

What are the benefits of radial piston motors in hydraulics?

Radial piston motors are known for their high efficiency, compact design, and robust construction. They deliver high torque at low speeds and offer precise control, particularly in heavy machinery. Additionally, they are durable, low-maintenance, and can be easily integrated into various systems.

Why is the efficiency of a radial piston motor so high?

Radial piston motors have a very high efficiency, especially at low speeds. This is due to the efficient power transmission of the radially arranged pistons, which act directly on the output shaft. This design minimizes friction losses and ensures optimal performance, thereby reducing energy consumption.

What are radial piston motors particularly suited for?

Radial piston motors are ideal for applications requiring high torque and low speeds. They are commonly used in heavy machinery, industrial plants, and specialized equipment, especially where a high starting torque is needed.

What characterizes the compact design of a radial piston motor?

The pistons are arranged radially around the drive shaft, allowing for a space-saving design. Unlike other motor types, which often grow in length, the radial piston motor remains compact in width without the need for additional components. This makes it easier to integrate into various systems.

What contributes to the long service life of a radial piston motor?

The radial arrangement of the pistons minimizes friction between the moving parts, reducing wear. Additionally, these motors are designed for high loads and demanding operating conditions, which further enhances their service life.

What should be considered when selecting a radial piston motor?

The selection of the right motor depends on several factors, including the required power, torque, and speed. The operating conditions, such as ambient temperature and available space, should also be taken into account. Additionally, operating pressure and torque are key factors that determine the motor's performance.
