AC Servo Motor Driven Pumps
ASR Series AC Servo Motor Driven Pumps

Revolution
Control System

The AS series provides variable flow by driving a piston pumpdirectly with an AC servo motor and controlling the rotational
speed in a range from zero to the maximum level.
This series allows for precise control of flow pressure byusing a dedicated AMS controller. t also offers exellent
response and repeatability.

ASE Series AC Servo Motor Driven Pumps
The ASE series pumps inherit the basic concept of the shaft
speed control from the AS series pumps and offer high cost
performance.
The pumps of this series offer easy shaft speed control forsystems that do not require as much precision, response, or
repeatability as the AS series pumps offer.
With the output flow and the discharge pressure controlled bya dedicated AMSE controller, precision, response andrepeatability of systems using the ASE series pumps havebeen improved compared with those using conventionalvariable displacement piston pumps.

● arge flow
The AMSR controller has a combination function that supports operation withlarge flow up to 3200 L/min (ASR10 × 16 units).

System Cofiguration
A feedback loop is by the AMSR controller thatcomputes deviations between control signals from themachine side (speed and pressure commands) andsensor signals to drive the AC servo motor
accordingly. Control parameters can be set digitallyby using dedicated software.
The AC servo motor is selected according to thetorque and shaft speed required to drive the hydraulicpump. The selection of an appropriate motor for theload condition is important.

ASE
System Cofiguration

A feedback loop is by the AMSE controller thatcomputes deviations between control signals from themachine side (speed and pressure commands) andsensor signals to drive the AC servo motor
accordingly. Control parameters can be set digitallyby using dedicated software.
The AC servo motor is selected according to thetorque and shaft speed required to drive the hydraulicpump. The selection of an appropriate motor for theload condition is important.

Shockless Type Proportional Directional and Flow Control Valves / Amplifiers
Shockless type proportional and flow control valves have been developed by employing the basic design concept
of“ ”series solenoid operated directional valves.
The maximum speed of actuators can be controlled optionally as the shockless type directional and flow control
valves have maximum flow rate adjustment functions, features which are not available on theseries solenoid

operated directional valves.
The power amplifiers for use with the shockless type directional and flow control valves have digital setting
systems allowing for excellent operational maneuverability and repeatability. They offer two types of slop mode
“SEC

STA T”and“T ME C

STA T”, and nine different types of shockless curves (one straight line

slope and eight waveforms). The optimum setting can be selected to suit any load condition.

ES are designed to simplify

hydraulic systems, to eliminate the use of pipe connections
and to save space, time and costs. The modular valves havestandardized interfaces ( S

1, CET,A) andthickness in accordance with each valve size. Any hydrauliccircuit can be created by stacking the modular valves in thecorrect sequence one upon another and bolting the various
stacks to a common manifold base.

●Modular valves remarkably minimize the installation areaand space.
● o expert skill is required to assemble. Changes oradditions to the circuit can be easily and quickly carried out.
● roblems such as oil leaks, vibration and noise which may

arise from pipes and tubes are minimized because pipes
and tubes are not necessary.
●The simple installation method of modular valves allows

for easy maintenance.

EH Series Proportional Electro-Hydraulic Control Valves
The EH Series on-board electronic proportional controls are compoundelectro-hydraulic products which merge the latest electronic and sensor
technology with Yuken's reputable E Series proportional controls. Yuken has
realized an industry leading position by creating compact hydraulicequipment that features high precision and reliability by unifying the amplifier,and sensor, all of which are required for proportional or servo control systems.
● roportional control systems or servo systems can be easily structured by simply

preparing the power source ( C) for controls and command signals along withthe hydraulic source.
Amplifiers exclusively used for the system or separately installed control panels
are unnecessary.
●By using built-in sensors
1 pressure and orifice openness, which can be converted to flow rate, can bedetected and controlled remotely.
2 along with a compound amplifier, a closed loop system can be structured.
3 sensor output signals or deviation signals at structuring closed loop system
can be monitored.
● isadvantages seen in ordinary hydraulic systems in which hydrauliccomponents, sensors and amplifiers are interconnected with each other but
installed separately are eliminated.

pumps feature greater energy-saving than those with fixed
displacement pumps.

●At Rated Output :Maximum Efficiency●At light-load :Significant Efficiency loss

Yuken's energy-saving hydraulic units and controllers
utilize rotational frequency control with an inverter. This
innovative configuration solves the problem of efficiency
losses suffered by induction motors operating at lightloads and ensures significant energy savings.

●Rotational frequency control is effective for reducing power loss.
Extensive energy saving is possible by detecting a load
