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.
What makes this movie stand out from the typical high school sports story is that the teenagers are undocumented immigrants, and the big game is a NASA-sponsored marine robotics competition. Like many other Hollywood movies, however, Spare Parts only tells part of the story. What the film shows -- and doesn’t show -- raises important issues affecting STEM education in the US.
Instead of sifting through huge amounts of technical data looking for answers to assembly problems, engineers can now benefit from 3M's new initiative -- 3M Assembly Solutions. The company has organized its wealth of adhesive and tape solutions into six typical application areas, making it easier to find the best products to solve their real-world assembly and bonding problems.
Load dump occurs when a discharged battery is disconnected while the alternator is generating current and other loads remain on the alternator circuit. If left alone, the electrical spikes and transients will be transmitted along the power line, leading to malfunctions in individual electronics/sensors or permanent damage to the vehicle’s electronic system. Bottom line: An uncontrolled load dump threatens the overall safety and reliability of the vehicle.
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.
