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.
One way to keep a Formula One racing team moving at breakneck speed in the pit and at the test facility is to bring CAD drawings of the racing vehicle’s parts down to the test facility and even out to the track.
Most of us would just as soon step on a cockroach rather than study it, but that’s just what researchers at UC Berkeley did in the pursuit of building small, nimble robots suitable for disaster-recovery and search-and-rescue missions.
Design engineers need to prepare for a future in which their electronic products will use not just one or two, but possibly many user interfaces that involve touch, vision, gestures, and even eye movements.
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.
