Today’s global actuation market is worth in excess of $30 billion, and is projected to continue growing as automation becomes the focus of increased production throughout the developing world. The majority of actuators used today provide simple linear motion for moving objects from one point to another. The need for advanced actuation increases along with the development of more sophisticated equipment.
Trends in automation to increase productivity are the driving factors for continued actuation growth and development. Yet, actuation enhancements are progressing at only a modest pace, presenting a challenge to keep up with the current and future market trends. Some of the factors include the need for less maintenance, higher efficiency, advanced connectivity (field buses), lower weight, and compact actuation solutions.
The three major types of actuation technology are electro-mechanical, hydraulic, and pneumatic. Each, of course, has its advantages and disadvantages.
