Sauer-Danfoss series S51 bent axis variable displacement motors
Series 51 Series 51-1 Bent Axis Variable Displacement Motors Technical Information Series 51 and 51-1 Bent Axis Variable Displacement Motors Technical Information General Description General Description Series 51 and 51-1 variable displacement motors are bent axis design units, incorporating spherical pistons. These motors are designed primarily to be combined with other products in closed circuit systems to transfer and control hydraulic power. Series 51 and 51-1 motors have a large maximum / minimum displacement ratio (5:1) and high output speed capabilities. SAE, cartridge, and DIN flange configurations are available. A complete family of controls and regulators is available to fulfill the requirements of a wide range of applications. Motors normally start at maximum displacement. This provides maximum starting torque for high acceleration. The controls may utilize internally supplied servo pressure. They may be overridden by a pressure compensator which functions when the motor is operating in motor and pump modes. A defeat option is available to disable the pressure compensator override when the motor is running in pump mode. The pressure compensator option features a low pressure rise (short ramp) to ensure optimal power utilization throughout the entire displacement range of the motor. The pressure compensator is also available as a stand-alone regulator. • The series 51 and 51-1 motors – Advanced technology today • The most technically advanced hydraulic units in the industry • SAE, cartridge, and DIN flange motors • Cartridge motors designed for direct installation in compact planetary drives • Large displacement ratio (5:1) • Complete family of control systems • Proven reliability and performance • Optimum product configurations • Compact, lightweight © 2009, Sauer-Danfoss Sauer-Danfoss can accept no responsibility for possible errors in catalogues, brochures and other printed material.

Momentary case pressure exceeding this rating is acceptable under cold start conditions, but still must stay below the maximum pressure rating. The minimum pressure provides proper lubrication at high speeds. Operation with case pressure in excess of these limits may result in external leakage due to damage to seals, gaskets, and/or housings. Case Pressure Rated pressure Maximum pressure (cold start) Minimum pressure (at rated speed) [psi] [44.0] [73.0] 1 [14.5] Rated Speed is the speed limit recommended at full power condition and is the highest value at which normal life can be expected. Maximum Speed is the highest operating speed permitted and cannot be exceeded without reduction in the life of the product or risking immediate failure and loss of driveline power (which may create a safety hazard). In the range between rated and maximum speed please contact your Sauer-Danfoss representative. Warning: The loss of hydrostatic drive line power in any mode of operation (e.g., forward, reverse, or “neutral” mode) may cause the loss of hydrostatic braking capacity. A braking system, redundant to the hydrostatic transmission must, therefore, be provided which is adequate to stop and hold the system should the condition develop. speed Limits min-1 (rpm) 060 080 110 160 at max. disp. 3600 3100 2800 2500 Rated speed at min. disp. 5600 5000 4500 4000 a t m a x . d i s p . 4 4 0 0 4 0 0 0 3 6 0 0 3200 Maximum speed1) at min. disp. 7000 6250 5600 5000 1) Contact your Sauer-Danfoss representative for max. speed at displacements between max. and min. displacement.

High pressure, which results from high load, reduces expected life in a manner similar to the affects of high load on other mechanical assemblies such as engines and gear boxes. There are load-to-life relationships for the rotating group and for the shaft anti-friction bearings. Continuous pressure is the pressure at which the hydrostatic system could operate continuously and still achieve acceptable hydrostatic life. This pressure level varies depending on operating speed, and on the life requirements for a particular application. While most mobile applications require system pressure to vary widely during operation, a “weighted average” pressure can be derived from a machine duty cycle. (A duty cycle is a means of quantifying the pressure and speed demands of a particular system on a percent time basis). Once a duty cycle has been determined or estimated for a specific application, contact your Sauer-Danfoss representative for system life ratings for the application. Maximum delta pressure is the highest intermittent pressure allowed, and is the relief valve setting. It is determined by the maximum machine load demand. For most systems, the load should move at this pressure. Maximum pressure is assumed to occur a small percentage of operating time, usually less than 2 % of the total. Both the continuous and maximum pressure limits must be satisfied to achieve the expected life. Minimum low pressure must maintained under all operating conditions to avoid cavitation. System Pressure Range, Input Maximum delta pressure Minimum low pressure Maximum pressure loop flushing bar 480 10 510 [psid] [7000] [145] [7400] An integral non-adjustable loop flushing valve is incorporated into all these motors. Installations that require fluid to be removed from the low pressure side of the system circuit because of cooling requirements or contamination removal will benefit from loop flushing. The integral loop flushing valve is equipped with an orificed charge pressure relief valve designed with a cracking pressure of 16 bar [232 psi]. Valves are available with several orifice sizes to meet the flushing flow requirements of all system operating conditions.

A tamper-proof cap is provided. hydraulic fluids Ratings and data are based on operating with hydraulic fluids containing oxidation, rust and foam inhibitors. These fluids must possess good thermal and hydrolytic stability to prevent wear, erosion and corrosion of the internal components. Fire resistant fluids are also suitable at modified operating conditions. Please see Sauer-Danfoss literature Hydraulic Fluids and Lubricants Technical Information for more information. It is not permissible to mix hydraulic fluids. For more information contact your Sauer-Danfoss representative. Suitable Hydraulic fluids: • • • • • • temperature and viscosity Hydraulic fluids per DIN 51 524, part 2 (HLP) Hydraulic fluids per DIN 51 524, part 3 (HVLP) API CD, CE and CF engine fluids per SAE J183 M2C33F or G automatic transmission fluids (ATF) Agricultural multi purpose oil (STOU) Premium turbine oils (for Premium turbine oils contact your Sauer-Danfoss representative). Temperature and viscosity requirements must be concurrently satisfied. The data shown in the tables assume petroleum-based fluids, are used. The high temperature limits apply at the hottest point in the transmission, which is normally the motor case drain. The system should generally be run at or below the rated temperature. The maximum temperature is based on material properties and should never be exceeded. Cold oil will generally not affect the durability of the transmission components, but it may affect the ability to flow oil and transmit power; therefore temperatures should remain 16 °C [30 °F] above the pour point of the hydraulic fluid. The minimum temperature relates to the physical properties of component materials. For maximum unit efficiency and bearing life the fluid viscosity should remain in the recommended operating range. The minimum viscosity should be encountered only during brief occasions of maximum ambient temperature and severe duty cycle operation. The maximum viscosity should be encountered only at cold start. Heat exchangers should be sized to keep the fluid within these limits. Testing to verify that these temperature limits are not exceeded is recommended. 16 520L0440 • Rev AC • Jul 2009 Series 51 and 51-1 Bent Axis Variable Displacement Motors Technical Information General Technical Specifications temperature and viscosity (continued) Fluid and filtration Viscosity Temperature Range 1) °C [°F] Minimum -40 [-40] intermittent, cold start Rated 104 [220] Maximum 115 [240] intermittent 1) At the hottest point, normally the case drain port.

A filter capable of controlling the fluid cleanliness to ISO 4406 Class 22/18/13 (SAE J1165) or better under normal operating conditions is recommended. The filter may be located either on the inlet (suction filtration) or discharge (charge pressure filtration) side of the charge pump. The selected filtration system must maintain a cleanliness level of 22/18/13 per ISO 4406. The selection of a filter depends on a number of factors including the contaminant ingression rate, the generation of contaminants in the system, the required fluid cleanliness, and the desired maintenance interval. Filters are selected to meet the above requirements using rating parameters of efficiency and capacity. Filter efficiency may be measured with a Beta ratio1) (βX). For simple suction-filtered closed circuit transmissions and open circuit transmissions with return line filtration, a filter with a β-ratio within the range of β35-45 = 75 (β10 ≥ 2) or better has been found to be satisfactory. For some open circuit systems, and closed circuits with cylinders being supplied from the same reservoir, a considerably higher filter efficiency is recommended. This also applies to systems with gears or clutches using a common reservoir. For these systems, a charge pressure or return filtration system with a filter β-ratio in the range of β15-20 = 75 (β10 ≥ 10) or better is typically required. Since each system is unique, the filtration requirement for that system will be unique and must be determined by test in each case. It is essential that monitoring of prototypes and evaluation of components and performance throughout the test program be the final criteria for judging the adequacy of the filtration system. Please see Sauer-Danfoss literature Hydraulic Fluids and Lubricants Technical Information for more information. 1) Filter βx-ratio is a measure of filter efficiency defined by ISO 4572. It is defined as the ratio of the number of particles greater than a given diameter (“x” in µm) upstream of the filter to the number of these particles downstream of the filter.

A braking system, redundant to the hydrostatic transmission must, therefore, be provided which is adequate to stop and hold the system should the condition develop. reservoir The function of the reservoir is to remove air and to provide make up fluid for volume changes associated with fluid expansion or contraction, possible cylinder flow, and minor leakage. The reservoir should be designed to accommodate maximum volume changes during all system operating modes and to promote deaeration of the fluid as it passes through the tank. A minimum reservoir volume equal to 1/2 to 1 1/2 times charge pump flow/min is suggested. This allows 30 seconds fluid dwell for removing entrained air at the maximum return flow. This is usually adequate to allow for a closed reservoir (no breather) in most applications. The reservoir outlet to the charge pump inlet should be above the bottom of the reservoir to take advantage of gravity separation and prevent large foreign particles from entering the charge inlet line. The reservoir inlet (fluid return) should be positioned so that the flow to the reservoir is discharged below the normal fluid level, and also directed into the interior of the reservoir for maximum dwell and efficient deaeration. 18 520L0440 • Rev AC • Jul 2009 Series 51 and 51-1 Bent Axis Variable Displacement Motors Technical Information General Technical Specifications motor bearing life The rated motor bearing life, Lh10 , shown in the table below, is based on a 90 % survival rate of shaft bearings, when operating at a speed of n = 1500 min-1 (rpm) with a charge pressure of 20 bar [290 psi] and without external shaft load.
