Packaging machinery still accounts for a relatively small portion of the market for servo technology, both in the U.S. and in Europe. But in both regions, the packaging industry's use of servos is expected to grow more rapidly than servo use in factory automation.
According to estimates by Motion Tech Trends (MTT, Inglewood, CA, the U.S. market for brushless servo axes consumed by packaging OEMs totaled $75 million in 2002. That was part of a $950 million market for servo consumption by all U.S. factory automation equipment suppliers. In Europe, packaging OEMs accounted for $85 million of a $790 million total factory automation market for brushless servo axes last year. These estimates include only sales of brushless electric motors and drives used in closed-loop applications.
The potential for growth is greatest in the U.S., where only about 20% of packaging machine axes today are equipped with servos, compared to a 40% penetration level in Europe, MTT estimates.
MTT projects 8% annual growth in brushless servo consumption by U.S. packaging OEMs over the next three to five years.
As energy efficiency becomes more and more a concern for makers of electronics devices, researchers are coming up with new ways to harvest energy from sound vibration, footsteps, and even electromagnetic fields in the air.
The government wants to study your brain, and DARPA wants to use similar information to give robots true autonomy beyond any artificial intelligence developed to date. Sound like science fiction? It's not.
A quick look into the merger of two powerhouse 3D printing OEMs and the new leader in rapid prototyping solutions, Stratasys. The industrial revolution is now led by 3D printing and engineers are given the opportunity to fully maximize their design capabilities, reduce their time-to-market and functionally test prototypes cheaper, faster and easier. Bruce Bradshaw, Director of Marketing in North America, will explore the large product offering and variety of materials that will help CAD designers articulate their product design with actual, physical prototypes. This broadcast will dive deep into technical information including application specific stories from real world customers and their experiences with 3D printing. 3D Printing is
