Targeting continuous-use applications such as pump, fan or scanner devices, these RoHS-compliant motors have cog-free motion, using a neodymium rare-earth-magnet rotor and "System Faulhaber" skewed winding. With electronic commutation, the bearings are the only limit to the life of these motors. The 1525 … BRC motor is 25 mm long and 15 mm in diameter and can achieve a continuous torque of 1.8 mNm at speeds as high as 16,000 rpm, and the 3153 … BRC motor is 53 mm long, and 31 mm in diameter; it has a 28 mNm continuous torque at speeds as high as 6,500 rpm.
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.
