PowerTRUE 90TM precision right-angle gearhead from Thomson Micron, LLC is a high-tech face gear that the company says provides smoother, quieter meshing and more efficient power transmission. The performance is made possible by leading-edge software and CNC machining technologies that create a continuous contact zone between the meshing wheel and involute pinion gears.
Pacific Scientific tested the POWERMAX II NEMA 23 frame step motor for more than a year prior to applying the motor and found that the motor operated continuously while submersed in hydraulic fluid. The company says that the POWERMAX II lends itself to this type of application because of the way the motor is constructed. The aluminum rear-end bell is replaced with an all in-one engineering polymer-molded assembly.
SRB rail assemblies from Pacific Bearing Co. include a stainless-steel option. These standard and stainless-steel rail assemblies use self-lubricating SimplicityTM linear bearings which provide performance in contaminated environments. The assemblies feature 6061-T6 aluminum-alloy T-Rail supports and 303 stainless-steel shafting.
Anorad Corp.'s piezo ceramic linear motor (PCLM) technology is the foundation for a three-axis laser micromachining system for biomedical fabrication workcells. In these production-floor systems, three 100-mm travel PCLM stages are configured in a rigid granite structure that provides better than 10 arc-second orthogonality between the vertical (focus) axis and the high-speed XY workpiece positioning stages.
According to a study by the National Institute of Standards and Technology, one of the factors in the collapse of the original World Trade Center towers on Sept. 11, 2001, was the reduction in the yield strength of the steel reinforcement as a result of the high temperatures of the fire and the loss of thermal insulation.

Robots are getting more agile and automation systems are becoming more complex. Yet the most impressive development in robotics and automation is increased intelligence. Machines in automation are increasingly able to analyze huge amounts of data. They are often able to see, speak, even imitate patterns of human thinking. Researchers at European Automation
call this deep learning.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
