Electric Actuators answer the Need for Speed - and so much more

15 December 2015

Thorite understands that there are problems experienced by companies currently using pneumatic actuators.

Higher operating speeds, more control, increased efficiency and enhanced feedback can all be provided by changing to electric actuators, but up to now the comparatively more expensive costs of these units has held them back. 

But thanks to Thorite's huge purchasing power, the cost of ownership of electric actuators is rapidly reducing to that of pneumatic cylinders! 

Thorite is offering Electric Drives from selected industry-leading manufacturers including Festo, Parker, SMC and Linak. This flexibility of choice means Thorite's specialist Automation Applications Team, using sizing software to check application parameters, can help customers specify the most appropriate solution to their precise application requirements, with all the benefits that electric actuation brings. 

These benefits include significantly increased speed - up to 10m/s maximum, with spectacular acceleration figures of 125m/s2, or twice that of a jet fighter. Control is much better too, with accuracy to 0.003mm and infinitely variable positioning and repeatability.

Electric actuators are 80% efficient, compared to just 15% for pneumatic cylinders, providing typical electricity savings of 50%. An integrated encoder gives constant and perfect position feedback and customers can add rotary actuators and grippers to the mix for a totally flexible "pick and place" solution. 

Previous differences in costs between electric and pneumatic actuation are now much reduced, and with Thorite's prices fast approaching parity there can be no doubt that electric actuators are the better value, higher performance, increased efficiency option for a wide range of automation applications.
