Models to extend the range are currently being developped. ► Advantages of LEDUC variable motors High quality know-how and materials. The design choices below ensure the reliability and long service life of LEDUC motors. High performance bearings for long service life. No gears between swashplate and rotating barrel, yields reduced noise levels. By design, the barrel is centered, which avoids radial stress and thus improves service life. Sealing designed specifically to withstand back presssure from the motor return drain circuit. 9-piston design, ensuring excellent operating regularity and constant torque. Injection of high pressure on piston heads reduces friction, heating and wear. Mechanical liaison between piston head and motor shaft guarantees there is no separation and thus ensures long service life. Maximum and minimum displacement setting via screws. Displacement controlled by setting piston. Different controls are offered: see page 13.

Using other fluids is possible but may require a modified motor. Please contact us with details of fluid. Recommended viscosity: Ideally: between 15 and 400 cSt, Maximum range: between 5 and 1600 cSt. ►Filtration of the hydraulic fluid The service life of the motors depends greatly on the quality and the cleanliness of the hydraulic fluid. We recommend minimum cleanliness as follows: For fluids at very high temperatures 194 to 239 °F (90 to 115 °C), we recommend a minimum cleanliness class of 19/17/14 according to ISO 4406. ►Rotating speeds Minimum rotating speed to obtain continuous rotation is 200 rpm (however, in certain conditions, the motor can run at speeds as low as 50 rpm). Maximum rotating speed is given for each model of motor. ►Installation positions LEDUC motors are made to operate in all positions (see details on page 15). ►Operating temperatures As standard, LEDUC motors are fitted with FKM seals (Viton ®). Operating temperatures: from -13 to 239 °F (-25 à 115 °C). As an option, HYDRO LEDUC proposes NBR seals, for operating temperatures from -40 to 176°F (-40 to 80°C). NAS 1638 class 9, SAE class 6, ISO/DIS 4406 class 20/18/15. IMPORTANT NOTE: Before start up, ensure the motor is filled with hydraulic fluid: See section on installation and start-up, page 15. Efficiency and operating conditions ►Direction of rotation The motors rotate clockwise or counter-clockwise depending on the direction of hydraulic flow entering the motor. Counter-clockwise rotation (CCW) Clockwise rotation (CW) T1 A B T1 A B T2 T2 ►Drain pressure It is essential to drain the motor, T1 and T2, to avoid excessive pressures on the shaft seal. Maximum acceptable internal pressure depends on motor rotation speed. However, following these guidelines will avoid problems during operation: Maximum internal pressure (Int P) regardless of rotating speed (continuous): 4 bar. Maximum pressure regardless of rotating speed: 5.5 bar. The maximum pressure in the motor housing must be greater than the external pressure (ext P). ►Acceptable forces applied to motor shaft Variable motors MV | MVSI | MVA 85 115 Fr daN 1300 1500 Fa N/bar 80 60 Fr Fa 5 Order code 6 MV ...

This can be set between 80 and 350 bar. Once set pressure has been reached, the motor starts changing displacement from Vmin to Vmax. Pressure remains stable, torque increases and speed decreases until Vmax is reached. Once Vmax has been reached, motor pressure can exceed set pressure if required. .

Pilot pressure can be set by a screw from 5 to 25 bar. Once pilot pressure has been reached, the motor starts changing displacement from Vmin to Vmax (standard configuration). From Vmax to Vmin on request. Important note: the pilot pressure line X must be drained when it is not under pressure (to ensure evacuation of leakage flow). 24 Coil supply voltage (Volt) Setting Vmin or Vmax displacement is done by applying an external electrical current via a solenoid, or not. Standard voltage of the coil is 24V (12V on request). When the coil is activated, the motor starts changing displacement from Vmin to Vmax (standard configuration). From Vmax to Vmin on request. . 13 Options | Accessories 14 S P E E D S E N S O R & I N D I C AT O R O F D I R E C T I O N O F R O TAT I O N LEDUC CODE: 093327 Codes 08 and 09 MV, MVA, MVSI series motors can be fitted with an induction type speed sensor, to measure rotating speed and also direction of rotation.

This valve is essential for all intensive uses of motors and contributes to long service life. The valve takes some hydraulic fluid from the return connection port (low pressure) and reinjects it into the motor housing. This is then evacuated via the motor drain line. Flushing valves are only available for use with motors with side ports (N1). ►S c h e m a t i c d r a w i n g o f t h e f l u s h i n g v a l v e A B Dimensions in inches (mm) are given only as an indication.

In ″shaft upwards″ position, make sure that the motor housing is completely filled with fluid. In installations where the position of the motor (H) is above the tank for the drain return, be sure the drain line is always submerged in fluid. If this is not the case, it is necessary to add a check valve on the drain line as shown the figure on right.
