This all-digital drive combines four motor control technologies into a single drive package: high-performance ac flux vector drive, high-horsepower servo drive and programmable motion controller and PLC technologies. Unique drive architecture enables the unit to control ac induction, ac synchronous, or brushless dc motors in the power range from 1 to 350 hp. All models provide extensive analog and digital I/O, feedback, serial communication capabilities, and dynamic braking control. Digital signal processor (DSP) technology implements the advanced space vector and motion control techniques and insulated gate bipolar transistor (IGBT) power devices directly control the motor. The unit supports encoders or resolvers, as well as operation, without a transducer for less-demanding, velocity-loop applications. Communications options include two fully-isolated RS-422/485 serial interfaces for connecting the drive to a process controller, communication network, or programmable controller, and an RS-232 port for connecting to a PC.
Inforbix is leveraging its CAD and product data access technology to power up a free iPad app that lets mobile users search and access engineering data.
Unlike his friends in engineering programs, blogger Jon Titus had little need for calculus except in a few of his college physical-chemistry labs and classes.
In the wake of the Chevy Volt fire investigations, sales are down, and General Motors' (GM) CEO Dan Akerson is blaming the downturn on a spate of bad publicity.
Thanks to embedded electronics, medical devices are getting smaller and smarter than ever. Pacemakers and implantable defibrillators are now able to call physicians. MRIs, CT scanners, and ultrasound machines are gaining mobility. And the venerable Band-Aid may soon be able to detect illnesses ranging from fevers to heart arrhythmias. On February 21, join Design News senior editor Charles Murray for a wide-ranging discussion, "Embedded Angles for Medical Products," which will explore the latest developments in medical electronics. The discussion will examine advances in medical device technology and offer an inside look at the embedded electronics behind it.
