The 19000 can-stack linear actuator uses the latest technology
in both materials and manufacturing. Technical enhancements compared with the
typical can-stack motor found in the marketplace includes optimized stator
tooth geometry, high energy neodymium magnets, custom engineered polymers and
larger ball bearings. The resulting system is a tiny linear actuator with high
force, high accuracy and durability.
The 1.22 inch (31mm) stroke length allows a
greater range of linear motion while maintaining the small mechanical footprint
for use in demanding applications requiring compact components and has a body
diameter of only 20 mm and a linear force of up to 180 oz (50N).
The high output can-stack line provides
exceptionally high force-to-size ratios and is useful for a variety of
applications including precision medical equipment, scientific instrumentation,
scanning devices and advanced optics.
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.
