MOTION CONTROL: Servometer®/PMG LLC precision, electrodeposited, nickel alloy, bellows-type, flexible shaft couplings provide torque capabilities from 2 oz-inch (1.4 Ncm) to 20 lb-ft (27 Nm), for shaft sizes ranging from .090 to 1 inch. Because of their flexibility, the low torque couplings can handle angular misalignment up to 31 degrees or parallel misalignments (shafts parallel but offset) up to .076 inch. In general, as flexibility increases, torque capacity decreases. For attachment to shafts, standard set screw hub, split hub with clamping collar or integral clamp hub styles are available. Unique characteristics of Servometer bellows couplings include zero backlash; vibration damping capability; zero cyclic speed variation during 360-degree rotation; very low elastic windup, due to torsional rigidity; and low side thrust on bearings because of lateral flexibility. Bellows couplings are for use in critical applications such as resolvers, encoders, servos, motion control devices and computers.
Advertised as the "Most Powerful Tablet Under $100," the Kindle Fire HD 6 was too tempting for the team at iFixit to pass up. Join us to find out if inexpensive means cheap, irreparable, or just down right economical. It's teardown time!
The increased adoption of wireless technology for mission-critical applications has revved up the global market for dynamic electronic general purpose (GP) test equipment. As the link between cloud networks and devices -- smartphones, tablets, and notebooks -- results in more complex devices under test, the demand for radio frequency test equipment is starting to intensify.
Much of the research on lithium-ion batteries is focused on how to make the batteries charge more quickly and last longer than they currently do, work that would significantly improve the experience of mobile device users, as well EV and hybrid car drivers. Researchers in Singapore have come up with what seems like the best solution so far -- a battery that can recharge itself in mere minutes and has a potential lifespan of 20 years.
Some humanoid walking robots are also good at running, balancing, and coordinated movements in group settings. Several of our sports robots have won regional or worldwide acclaim in the RoboCup soccer World Cup, or FIRST Robotics competitions. Others include the world's first hockey-playing robot and a trash-talking Scrabble player.
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.
