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 2014 Ig Nobel Prize in Physics was awarded to Dr. Kiyoshi Mabuchi and his team members for their work measuring the slipperiness of banana peels. Turns out they're slipperier with the yellow side up.
Many scientists have been working battery-free ways to power wearable electronics that can replace bulky battery packs, particularly through the use of energy-harvesting materials. Now a team of researchers in China have upped the game by developing a lightweight and flexible solar cell that can be woven into two-way energy-harvesting fabric.
