MOTION CONTROL: B&R Industrial Automation has expanded its drive technology product spectrum and is now featuring frequency inverters. All demands of machine manufacturing are met with performance levels of 0.18 to 500 kW. This is an addition to B&R’s successful ACOPOS line of servo controllers, enabling them to supply a complete line of drive technology.The three series with the name ACOPOSinverter S44, X64 and P88 are equipped with serial, X2X and POWERLINK interface and fully integrated in Automation Studio. An additional advantage is easy maintenance because all parameters are saved in the CPU. This allows easier and more efficient commissioning of devices in the series production. The flagship product, the ACOPOSinverter P84, prevents the transformation of braking energy into heat via an optional regenerating unit or by connecting the dc bus voltage, making it more energy and cost efficient. “Our customers have often asked about frequency inverters, so it made sense to add this product to our portfolio,” says Hans Wimmer, managing director of B&R in Eggelsberg.
Engineers at the University of San Diego’s Jacobs School of Engineering have designed biobatteries on commercial tattoo paper, with an anode and cathode screen-printed on and modified to harvest energy from lactate in a person’s sweat.
