Sauer-Danfoss Introduces New Bent Axis Motors

Sauer-Danfoss, Lincolnshire, Ill., has released its new H1 80cm3 and 110cm3 bent axis motors, the first sizes in a new series of motors designed to complement the growing family of H1 axial piston pumps. With the introduction of the H1 bent axis motors, Sauer-Danfoss is now able to provide 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, according to the company.

The new H1 bent axis variable displacement motors have been designed to ensure reliability and quality. Optimized for electrical control, they are fully PLUS+1TM Compliant, enabling seamless integration with Sauer-Danfoss’ electronic machine control architecture – Plug and Perform. And with an IP 69 rating, the electrical controls are able to withstand harsh working environments.

“We are pleased to introduce the H1 bent axis motors, which perfectly complement the successful H1 pump family,” said Hans-Peter Nissen, product portfolio manager. “With proven 32-degree bent axis technology, zero degree capability and higher overall efficiency, our new motors offer OEMs a number of significant advantages. The H1 propel system provides improved horsepower management, and enables advanced anti-slip or wheel-assist control functions.”

An extensive simulation and testing program for the H1 bent axis motors has resulted in significant improvements in overall efficiency and an extremely low pressure drop in the galleries. This helps improve fuel economy and frees power for other vehicle functions, enhancing operating performance and increasing productivity. “Tier 4 and Euro IIIb emission standards will require intelligent utilization of engine power and this will be strongly supported by our new H1 family of products,” said Nissen.

A key feature of the new H1 motors is their zero degree capability. The ability to seamlessly reduce the angle to zero degrees means there is no torque interruption, or sudden change in speed when switching from, for example, work range to travel range. This enhanced control is not only more precise, but also improves the feel of the system during operation. “Zero degree capability enables OEMs to provide additional features including accurate anti-slip and torque control functions, which increase vehicle productivity and optimize power utilization,” said Nissen. The zero degree capability also enables a wheel assist solution without the need for additional technology. “Even true two-speed applications, for example a crop sprayer, can be supported by this great feature,” Nissen said.
