The new SilverPak 23DE, an integrated Nema 23, High Torque, 1.8° bipolar step motor, microstepping driver and encoder is designed to reduce overall design time and system cost for a wide array of step motor applications needing high torque. The SilverPak 23DE is 2.25 inches in width and is offered in three body lengths: 2.52, 2.96 and 3.89 inches. Depending on its stack size, the integrated motor/driver is capable of producing up to 294 oz-inch of holding torque. The SilverPak 23DE operates from 15 to 48V dc and the available phase current ranges from 0.3 to 3A peak. This integrated motor/driver combination features jumper configurable step resolutions ranging from 2X microstepping up to 256X microstepping and 4 selectable damping modes, optically isolated step, direction and disable/enable inputs, under-voltage and over-temperature protection, and Pole Damping Technology™ (PDT). Options available with the built-in encoder are Tracks up to 100,000 cycles/sec, 32 to 1250 CPR, Max 5000 pps, 2 channel quadrature TTL squarewave single ended outputs and optional index.

Truchard will be presented the award at the 2014 Golden Mousetrap Awards ceremony during the co-located events Pacific Design & Manufacturing, MD&M West, WestPack, PLASTEC West, Electronics West, ATX West, and AeroCon.
In a bid to boost the viability of lithium-based electric car batteries, a team at Lawrence Berkeley National Laboratory has developed a chemistry that could possibly double an EV’s driving range while cutting its battery cost in half.
Using Siemens NX software, a team of engineering students from the University of Michigan built an electric vehicle and raced in the 2013 Bridgestone World Solar Challenge. One of those students blogged for Design News throughout the race.
For industrial control applications, or even a simple assembly line, that machine can go almost 24/7 without a break. But what happens when the task is a little more complex? That’s where the “smart” machine would come in. The smart machine is one that has some simple (or complex in some cases) processing capability to be able to adapt to changing conditions. Such machines are suited for a host of applications, including automotive, aerospace, defense, medical, computers and electronics, telecommunications, consumer goods, and so on. This discussion will examine what’s possible with smart machines, and what tradeoffs need to be made to implement such a solution.
