hydraulic servo motor
What is hydraulic servo motor?
A hydraulic servo-motor for the control of an internal combustion engine which is equipped with a servo-piston, with a fuel quantity control mechanism and with a control slide valve member arranged coaxially to the servo-piston which itself is in operative connection with a centrifugal governor; a working medium under
How does a hydraulic servo valve work?
Control.
A servo valve receives pressurized hydraulic fluid from a source, typically a hydraulic pump.
It then transfers the fluid to a hydraulic cylinder in a closely controlled manner.
Typically, the valve will move the spool proportionnaly to an electrical signal that it receives, indirectly controlling flow rate.Servo pump drives for the hydraulic supply consist of a fixed displacement pump driven by a servo motor.
The flow rate and pressure can be controlled precisely by highly dynamic changing of the motor speed.
If neither flow rate nor pressure are required, the motor stops and does not consume any energy.
What are the advantages of hydraulic servo system?
Servo-hydraulic machines combine the advantages of hydraulic power transfer with the advantages of servo-drive technology: High output densities, low inertias and cost-effective and robust drive elements meet dynamic and precise speed control.
Energy consumption is thus reduced significantly.
