MOTION CONTROL:Lin Engineering recently announced the release of its new and improved NEMA 17 Brushless DC (BLDC) motors, the BL17 line. These motors are best for applications that entail high speed and high dynamic torque.
The BL17 line of BLDC motors provides quiet and smooth operation regardless of speed range; speeds of up to 4000RPM are easily attainable. The motors are available in four body lengths: 1.7, 2.4, 3.2 and 3.9 inch, and is capable of up to 106 oz-inch of peak torque depending on the stack size. These motors are also great for those who prefer velocity control with an analog input, do not need holding torque and may be having reliability issues with an existing Brush dc motor.
These motors can additionally be ordered with custom shaft and winding variations to meet exact speed/torque/voltage point.
The promise of the Internet of Things (IoT) is that devices, gadgets, and appliances we use every day will be able to communicate with one another. This potential is not limited to household items or smartphones, but also things we find in our yard and garden, as evidenced by a recent challenge from the element14 design community.
If you didn't realize that PowerPoint presentations are inherently hilarious, you have to see Don McMillan take one apart. McMillan -- aka the Technically Funny Comic -- worked for 10 years as an engineer before he switched to stand-up comedy.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
