MOTION CONTROL: H2W Technologies’ compact, industry-standard, 12 lb Linear Steppers (53 N continuous Force, 16 lb, 71 N peak force) travel at 80 inch/sec (2m/sec), with 1 micron (0.00004 inch) resolution, and can operate in any axis. They feature 1G acceleration and are the ideal choice for new and existing gantry robots, pick-and-place systems, wire bonders, parts transfer, fiber optic, semiconductor, medical and other precision robotic applications.
Available with a hard chrome, solid or hollow platen (track) in lengths up to 144 inch (3.65m), (longer travels can be achieved by supplying the platens in sections), the H2W Technologies industry-standard 12 lb Linear Stepper is capable of very precise position, velocity and acceleration control when integrated with a microstepping drive and indexer. The resolution of these 2- or 4-phase motors is determined by the driver. One full step equals .010 inch (250 microns) and one microstep equals .00004 inch (1 micron). Ideal for open loop positioning applications with moderate payloads, the 12 lb Linear Stepper can also be operated as a brushless linear servo with up to 5 Gs of acceleration and no loss of accuracy.
Capable of generating 12 lb (53 N) of continuous force, these single-axis linear steppers have a forcer (motor), air bearings, side guide bearings and platen (track) integrated into a compact, low-profile, package. The forcer connects to a motion control system via flying leads or “D” connector. Multiple forcers can operate on a single platen at the same time. Linear steppers can also be custom-designed to meet a particular application’s requirements.
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.
