This compact unit includes a bipolar, 1.8-degree NEMA 17 step motor, along with an integrated microstepping driver and intelligent controller. Its affordable design needs no outside equipment. RoHS-compliant versions are available upon request. It comes in 2.76, 2.99 and 3.31-inch lengths and puts out up to 85 o-inches of holding torque, depending on motor stack size, with custom windings available for free. It has output currents of 0.1 to 1.5 amps peak, input voltage of 7V dc to 28V dc, and 16 kbytes of onboard memory. It has a general-purpose input switch for manual motor positioning and an open collector output switch that can put out 100 mA. It can be programmed for stand-alone operation with no PC, and has low enough power dissipation that it needs no heat sink. Its StallGuard™ stall detection feature means no encoders are needed.

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.
