The Growing Popularity of Electric Actuation
Increasingly complex machine requirements are leading manufacturers to consider alternative linear motion technologies, to ensure they are selecting the best solution for their applications.
While the operational benefits and tradition of pneumatic actuators are well established, the popularity of electric actuation in recent years has continued to grow as they offer precision control, better flexibility, guaranteed repeatability and easy connectivity.
The IMI Norgren ELION rod-style electric actuator adds to IMI Precision Engineering’s comprehensive linear motion portfolio. An advanced range of electric actuators, based on ISO 15552 that’s has been designed for safer, smoother and energy efficient operation.
Complemented by a range of high-performance AC servo motors and drives, IMI Precision Engineering can offer a complete electric actuator solution for any application.
Axial or parallel motor configurations are available depending on the load transmission and space available, as well as a wide range of accessories including mountings, switches and cables to suit your application needs.
The benefits
Electric actuators can provide the highest degree of precision-control over the linear motion stroke, offering unmatched performance when it comes to controlling speed, position, accuracy and repeatability. For example, accuracies of +/- 0.02mm are possible with a repeatability of +/- 0.01mm.
Multiple intermediate positions can be achieved and the in-built positioning flexibility allows several actuators to move in unison, changing speed without the need to stop or overrun a position.
In addition, acceleration and deceleration control also allows the cylinders to glide into position without stopping abruptly, making electric actuation suitable for applications where vibration and disruptive movement is not acceptable.
In certain applications such as large, multiple axis machines, a combination of electric and pneumatic actuation can be appropriate as there may be both simple and complex linear motion positioning requirements.
With extensive experience in industrial automation, and in designing systems to help machines move reliably, IMI Precision Engineering have the expertise to solve customers' problems and meet customers' needs, however complex they may be.
So, whether you need drives with a variety of protocols, or a mixture of technologies, IMI Precision Engineering can ensure you achieve the optimum solution in the most appropriate combination. Precisely, accurately, reliably and repeatedly.
Once in a lifetime
The intuitive, easy to use online configuration tool gives you the added flexibility to specify the correct actuator for your requirements. You can configure using product attributes such as size, stroke and mountings; or application attributes such as distance, load, speed or lifetime.
If you need your actuator to move from fully in-stroke, pause for 15 seconds, move to mid-stroke in half a second and rest there for two minutes, the configurator will complete all the necessary calculations to ensure that you are recommended the most appropriate actuator.
Once configured, you won’t have to repeat the process to order the same product again in the future. In other words: configure once – buy for life.
