Eaton’s HP30 High Torque Low Speed Hydraulic Motor Offers High Starting Torque Efficiency and Improved Overall Efficiency

With a displacement range of 344 to 677 cm3/r and a torque of up to 2900 Nm, the motors are designed for a pressure level of 310 bar continuous and 345 bar intermittent. The maximum flow rate is 265 l pm.

The HP 30 has a very compact envelope and class leading starting torque efficiency which often enables a smaller motor to be specified. With these characteristics the HP 30 was designed considering various scenarios of demanding hydraulic drives applications like winches, mobile construction machinery, conveyors and drilling equipment.

In addition, the HP 30 motor features two-speed capability. It is able to shift on the fly smoothly between high torque low speed and high speed low torque modes under dynamic loading. This offers potential savings by simplifying the drivetrain and opens up other new applications.

The option of a spring applied hydraulic brake allows for load holding without the need for continuous hydraulic power. The versatility of the HP 30 is also shown by the fact that it offers series circuit capability, and that it can be equally employed in closed or open circuit applications. An optional feature is ATEX certification, enabling application in potentially explosive environments such as mining or oil and gas platforms.

Regardless of what application the HP 30 motor is used for, the customer will benefit from its energy efficiency. John Taylor, EMEA Product Manager at Eaton: “The HP 30 is designed from scratch with the goal of high power, perfect dynamics and maximum efficiency.” Low internal pressure loss results in less heat generation, less energy wastage, and helps improve the overall efficiency of the system. Reducing the cooling requirement could offer weight and space savings. Together with high starting torque, these features offer HP 30 best in class performance.

HP 30 has evoked great interest since it was first released. With the motor’s new capability to operate in open circuit applications and with additional features, Eaton expects to convince even more customers of the exceptional value HP 30 offers. “With its high power capability and flexibility, we expect many customers to switch to HP 30, either from competitive products or from competitive technologies, such as small radial piston motors,” added John Taylor.

HP 30 expands the already extensive Char-Lynn high speed low torque Geroler motor series. Eaton has the broadest range of Gerotor and Geroler motors available in the market, and is the largest supplier of this technology globally.
