Sauer-Danfoss introduces H1 60cm³ Bent-Axis Motor

Nordborg, Denmark, – Sauer-Danfoss has released its new H1 60cm³ bent axis motor, the next size in a series of motors designed to complement the growing range of H1 axial piston pumps.

With the introduction of the H1 bent axis motors, Sauer-Danfoss offers a complete H1 transmission system, optimized around electrical control. The H1 motors not only provide OEMs with improvements in reliability and flexibility, but also provide higher overall efficiency, resulting in lower fuel consumption and reduced life cycle costs. Typical applications that will benefit from the new H1 bent axis 60cm³ motor are rough terrain forklifts, combines, sprayers, road rollers, wheel loaders and road building equipment.

The H1 motors are optimized for electrical control and are fully PLUS+1^TM Compliant, enabling seamless integration with Sauer-Danfoss’ electronic machine control architecture. To withstand the harshest working environments, the electrical controls are designed with an IP67 and IP69K rating. The H1 60cm³ bent axis motor is an evolution of proven technologies centered on a high displacement ratio of 32 degrees, zero degree capability, and higher overall efficiency. This combination provides a unique range of benefits that fit any OEM’s requirements for machine design.

The H1 motors feature improvements in overall efficiency and an extremely low pressure drop within the fluid galleries of the motor. The H1 bent axis motors have a 6 percent efficiency gain at maximum displacement (high torque working cycle), compared to the nearest competitor. Combined with H1 pump efficiencies, this helps improve fuel economy and provides power savings for other vehicle functions, enhancing operating performance and increasing productivity.

A key feature of the new H1 motors is their zero degree capability. It provides for seamless ‘on the go’ shifting from 32 to zero degrees, such as in wheel assist applications, providing for a smooth transition with little or no torque interruptions or sudden speed changes. This enhanced control is not only more precise, but also improves the feel of the system during operation. The H1 motor will also shift seamlessly between two speed ranges, for example, work mode and travel mode, regardless of displacement settings.
