Kyntronics SMART Electro Hydraulic Actuator (SHA) Advantage

The Kyntronics SHA, an electro-hydraulic actuator, combines the best features of hydraulic power with the precision of servo control used in electro-mechanical actuators while eliminating the shortcomings of those approaches. The result is an actuation solution with up to 170,000 LBs (755kN) of force and superior functionality at a lower price point.

The Design Advantages of the SHA Include:

All-In-One Complete Solution

• Servo Motor, Controller, Software and Actuator
• Factory tuned, setup & tested, ready to install

Small Footprint – Energy Efficient

• Maximum force density;
  superior to electro-mechanical actuators
• Saves energy, only consumes power on demand

Precision Servo Control

• Accurate control of position, force and speed

Eliminates the HPU, Hoses and other Components

• No leak points, saves space, much quieter than hydraulics
• Lower cost, less engineering and manufacturing time

Reliable and Durable

• No metal-to-metal wear points unlike roller or ball screw actuators
• Resists shock loads
• A totally closed system results in minimal maintenance

Advantages of the Kyntronics SHA over Hydraulic Actuation:

• All-In-One, Factory Configured, Ready to Install
• Closed System, no leaks, minimal maintenance
• Eliminates the HPU saving space, reducing noise, eliminates the mess
• Energy efficient, only consumes power when operating
• Precision servo control of position, speed and force

Advantages of the Kyntronics SHA over Ball Screw & Roller Screw Actuators:

• Higher “force-density” than EMAs, results in a smaller footprint and package
• The SHA incurs a small cost increase as force and load requirements increase (see following graph)
• Tolerant of “shock loads” which are very damaging to EMAs
• Highest efficiency, no metal-to-metal contact improves reliability
• The SHA Cannot be “back-driven”. EMAs require an expensive brake
