Festo Drives > Electric cylinders that provide flexibility and control at a lower cost

Festo electric drives are available in 4 standard kinds:

lead screw, ball screw, linear motors and roller screw .

Each technology includes its very own limitations and advantages.

Ball screws are rapid, precise and effective, however the preliminary expense is greater than lead screws. Festo  Linear motors  for example the DNCE-LAS  has the greatest dynamics with greater than one hundred and twenty five m/sec² acceleration, however payloads are restricted to approximately six kilograms in comparison to sixty kilograms  for a ball screw that has the identical roller screw. This design gives higher feed forces as well as higher velocities, however they need a higher funding therefore expenses could be a lot more than ball screws.

In comparison to hydraulic and pneumatic actuators, Festo electric drives provide cleaner plus a more manageable choice.  A lot of engineers incorrectly presume that electric drives give a much more energy efficient remedy if they compare it to pneumatics. In holding and pushing applications (which is the standard for cylinders), pneumatics use reduced power for the identical application, specifically in vertical use. As a result electric drives ought to always be validated on their flexibility and controllability in comparison to pneumatics and not on energy effectiveness. If hydraulic installations could be eliminated in favour of electrical cylinders, then the set-up costs are normally much more cost effective.

You will discover numerous design issues to take into consideration when you use electric drives. For instance the environment is a major issue. Contrary to hydraulics and pneumatics, there isn't any positive pressure within the actuator and thus moisture and dirt can become a problem. Mix this with the cylinder creating an internal vacuum cylinder. A lot of manufacturers provide IP65 electric cylinders, however attention should be taken when selecting these. Could they be only IP65 when static? Festo provides a threaded breathing port on both of the Festo DNCE and Festo ESBF selection of electric cylinders that permits the actuator to breathe throughout higher dynamic movements therefore creating a true IP65 solution.

Contrary to belt drives and gantry ball screws, electrical cylinders are hardly ever utilized for pick + place applications. The primary functions in automation are format setting on machines, high speed reject and positioning, high force lifting and push and pull or pressing applications. Most of the electric cylinder product range from Festo meets the ISO 15552  regulations that guarantee it is able to share guiding systems with a pneumatic selection of cylinders, increasing the application field further.

A brand new cost effective addition to the Festo electric cylinders range is the Festo EPCO range.  With the EPCO Designers can be designing a positioning system into a machine with cylinder motor, servo controller and cables all built-in for a lower price of six hundred pounds.

Festo electric cylinders advantages are that it has a wide selection of options that are available for lots of different applications.

For instance the IP65 food grade is included, e-camming servo control, lower cost, High 17kN of feed force and next day availability.
