These packages combine a 5-phase stepping motor with a microstepping driver. There is less vibration, speed fluctuations and audible noise due to a new, smooth drive function. The driver offers 25 preset angle selections up to a capability of 250 microsteps per full step during microstep operating mode. The basic step angle can be adjusted for a 2-phase stepping motor's step angles. This makes it easy to switch over from the 2-phase microstep mode, all without having to change input pulses. It measures 2.56 x 1.77x .98 inches, nearly half the size of a conventional full step driver, and it weighs only 1.4 ounces. It comes in 20 mm (0.79-inch), 28 mm (1.10-inch), 42 mm (1.65-inch), and 60 mm (2.36-inch) sizes. It comes with standard, high-torque, or geared model motors.

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.
