MOTION CONTROL: The DEC Module 24/2 from maxon motor is a digital 1-quadrant amplifier with speed controller for brushless EC motors with Hall Sensors up to 48W and a surface area measuring less than 5 cm2. The DEC module 24/2 is a miniaturized, powerful plug-in module that can be seamlessly integrated into most complex applications with little effort. The wide supply voltage range of 8-24V dc (alternatively 5V dc) and a continuous output current of 2A, permits flexible multifunctional operation at a high efficiency factor. The amplifier offers a large number of inputs and outputs (such as enabling, speed ranges, direction of rotation presetting, current limiting, operational status) and comprehensive protection features (such as over-current, undervoltage/overvoltage, thermal overload, blockage and short circuit). The amplifier is also designed for a maximum motor speed of 80,000 rpm. Two connector arrays arranged in a 2.54 mm (0.1 inch) pattern support easy connectivity and integration into the OEM-side motherboard.
The Dutch are known for their love of bicycling, and they’ve also long been early adopters of green-energy and smart-city technologies. So it seems fitting that a town in which painter Vincent van Gogh once lived has given him a very Dutch-like tribute -- a bike path lit by a special smart paint in the style of the artist's “Starry Night” painting.
For decades, engineers have worked to combat erosion by developing high-strength alloys, composites, and surface coatings. However, in a new paper, a team at Jilin University in China turned to one of the most deadly animals in the world for inspiration -- the yellow fat-backed scorpion.
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.
