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 engineers and inventors of the post WWII period turned their attention to advancements in electronics, communication, and entertainment. Breakthrough inventions range from LEGOs and computer gaming to the integrated circuit and Ethernet -- a range of advancements that have little in common except they changed our lives.
Neil Fromer is the executive director of the Resnick Institute, a program for energy and sustainability at the California Institute of Technology, working to develop new ideas and research technologies related to providing a sustainable future. He spoke to us about the severity of the current drought in California and how solar energy can help prevent such situations in the future.
