Features

– Variable plug-in motor with axial tapered piston rotary group of bent axis design for hydrostatic drives in open and closed circuits

– Easy assembly, simply «plugs-in» into mechanical gearboxes (no installation tolerances to consider)

– The design of the motor with the mounting flange in the cen-ter of the housing allows it to be almost fully integrated into a mechanical gearbox to give an extremely compact unit– For use in mobile applications– Installation ready and tested unit

– The displacement is infinitely variable from Vg max to Vg min = 0– The output speed is dependent on the flow of the pump and the displacement of the motor

– The torque increases with the pressure differential between the high and low pressure side and with increasing displace-ment

Technical Data

Hydraulic fluid

Before starting project planning, please refer to our data

sheets RE 90220 (mineral oil), RE 90221 (environmentally ac-ceptable hydraulic fluids) and RE 90223 (HF hydraulic fluids) for detailed information regarding the choice of hydraulic fluid and application conditions.

The A6VE variable plug-in motor is unsuitable for operation with HFA. If HFB, HFC and HFD or environmentally accept-able hydraulic fluids are being used, the limitations regarding technical data and seals mentioned in RE 90221 and RE 90223 must be observed.

When ordering, please indicate the used hydraulic fluid.Operating viscosity range

For optimum efficiency and service life, select an operating vis-cosity (at operating temperature) within the optimum range of

nopt = optimum operating viscosity 16 to 36 mm2/sdepending on the circuit temperature (closed circuit) and tank temperature (open circuit). Limits of viscosity range

The limiting values for viscosity are as follows:Sizes 28 to 160:

nmin = 5 mm2/s short-term (t < 3 min) at max. perm. temperature of tmax = +115°C.

nmax = 1600mm2/s, short-term (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 rpm, t O

nly for starting up without load. Optimum operating min = -40°C).viscosity must be reached within approx. 15 minutes.Size 250:

nmin = 10 mm2/s,short-term (t < 3 min)

at max. perm. temperature of tmax = +90°C.

nmax = 1000 mm2/s, short-term (t < 3 min) at cold start (p ≤ 30 bar, n ≤ 1000 rpm, t O

nly for starting up without load. Optimum operating min = -25°C). viscosity must be reached within approx. 15 minutes.Note that the maximum hydraulic fluid temperature of 115°C (90°C at size 250) must not be exceeded locally either (e.g. in the bearing area). The temperature in the bearing area is - depending on pressure and speed - up to 12 K higher than the average case drain temperature.

Special measures are necessary in the temperature range from -40°C to -25°C (cold start phase); please contact us.For detailed information about use at low temperatures, see RE 90300-03-B.

Filtration

The finer the filtration, the higher the cleanliness level of the hydraulic fluid and the longer the service life of the axial piston unit.

To ensure functional reliability of the axial piston unit, the hy-draulic fluid must have a cleanliness level of at least 20/18/15 according to ISO 4406.At very high hydraulic fluid temperatures (90°C to max. 115°C), at least cleanliness level of

19/17/14 according to ISO 4406 is required.

If the above classes cannot be observed, please contact us.

Speed range

No limit to minimum speed nmin. If uniformity of motion is re-quired, speed nmin must not be less than 50 rpm. See table of values on page 5 for maximum speed.

Technical Data

Shaft seal ring

Permissible pressure load

The service life of the shaft seal ring is affected by the speed of the motor and the case drain pressure. It is recommended that the average, continuous case drain pressure at operating temperature 3 bar absolute not be exceeded (max. permissible case drain pressure 6 bar absolute at reduced speed, see dia-gram). Short-term (t < 0.1 s) pressures spikes of up to 10 bar absolute are permitted. The service life of the shaft seal ring de-creases with an increase in the frequency of pressures spikes.The case pressure must be equal to or greater than the external pressure on the shaft seal ring.

Temperature range

The FKM shaft seal ring is permissible for case temperatures of -25°C to +115°C.

Note:

For application cases below -25°C, an NBR shaft seal ring is necessary (permissible temperature range: -40°C to +90°C). Please state NBR shaft seal ring in plain text when ordering. Please contact us.

Effect of case pressure on start of control

An increase in the case pressure has an effect on the following controls when control of the variable motor begins:

HA1T (sizes 28 to 160) _________________________increaseHD, EP, HA, HA.T (size 250) _____________________increaseDA __________________________________________decreaseThe start of control is set in the factory at a case pressure of pabs = 2 bar (sizes 28 to 160) and pabs = 1 bar (size 250).

Table of values

(theoretical values, without efficiency and tolerances; values rounded)

1) The minimum and maximum displacements are infinitely variable, see ordering codes on page 2.

(default settings for sizes 250 unless specified in order: Vg min = 0.2 Vg max, Vg max = Vg max).

2) V = 0.75 x Vg1g max (approx.)

3) Sizes 28 to 160: Δp = 400 bar; size 250: Δp = 350 bar

Caution:

E xceeding the permissible limit values may result in a loss of function, a reduction in service life or in the

destruction of the axial piston unit.

Other permissible limit values with respect to speed variation, reduced angular acceleration as a function of the fre-quency and the permissible startup angular acceleration (lower than the maximum angular acceleration) can be found in data sheet RE 90261.

Flush and Boost Pressure Valve

The flush and boost pressure valve is used to remove heat from the closed circuit and to ensure that a minimum boost pressure is present (opening pressure 16 bar, fixed; note when setting primary valve). A side effect is the flushing of the case.Warm hydraulic fluid is directed from the respective low pres-sure side into the motor case. This is then fed into the tank, together with the case drain fluid. The hydraulic fluid drawn out of the closed circuit in this way must be replaced by cooled hydraulic fluid that is supplied by the boost pump.

In an open circuit, the flush and boost pressure valve is used solely to flush the case from the return line.

The valve is fitted on the variable motor or integrated into the control unit (depending on the type of control and the size).

Orifices can be used to adjust the flushing volumes as re-quired.

Speed Measurement

Version "F" (sizes 55 to 160) prepared for speed measurement

The A6VE...F ("prepared for speed measurement", i.e. without sensor) versions have teeth on the rotary group. The rotat-ing, toothed rotary group generates a signal in proportion to the speed. The signal is picked up by a sensor and can be forwarded for evaluation.

Version F is suitable for mounting to the HDD Hall-effect speed sensor (see RE 95135). The HDD sensor is flanged with two fixing screws at the specified port. In the standard version, the port is plugged with a pressure-resistant flange cover. We recommend ordering the A6VE variable motor with

mounted sensor. Please specify the ordering code for the sen-sor separately.Circuit diagram

Installation Notes

General

During commissioning and operation, the axial piston unit must be filled with hydraulic fluid and air bled.

This is also to be observed following a relatively long standstill as the system may empty via the hydraulic lines. The motor case drain connection (i.e. T1/T2) must be directed to the tank via the highest case drain port.In all operational states, the case drain line must flow into the tank below the minimum fluid level.Installation position

See examples below. Additional installation positions are available upon request.Below-tank installation (standard)

General Notes

– The A6VE motor is designed to be used in open and closed circuits.

– Project planning, assembly, and commissioning of the motor require the involvement of qualified personnel.– The service line ports and function ports are only designed for mounting hydraulic lines.

– During and shortly after operation, there is a risk of burns on the motor and especially on the solenoids. Take suitable safety precautions, e.g. wear protective clothing

– There may be shifts in the characteristic depending on the operational state of the motor (operating pressure, fluid temperature).– Tightening torques: - The tightening torques specified in this data sheet are maximum values and must not be exceeded

(maximum values for screw thread).

Manufacturer's instruction for the max. permissible tightening torques of the used armatures must be observed!

- For DIN 13 fixing screws, we recommend checking the tightening torque individually according to VDI 2230 Edition 2003.– The data and information contained herein must be adhered to.
