This system's NEMA17 high-torque, brushless motor design uses innovative techniques to control current flow through the motor, reducing resonance throughout the MDrive's speed range and making it quieter. It can take a broad input voltage range from +12 to +48 V dc. It runs at an extended operating range of -40 to 85C, and its general purpose I/O, running to +24 Volts, has been expanded from 4 to 8. The MDrive17 has a full-featured, easy-to-program instruction set, a 10-bit analog input, 0-5 MHz step clock rate, and 20 microstep resolutions up to 51,200 steps per revolution. Expanded features make electronic gearing possible with an output clock generated fixed to the internal step clock, or by following a rotary or linear axis at an electronically controlled ratio. Options and accessories include a long life linear actuator; encoders; integrated planetary generator; control knob and linear slide.
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.
