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.

From home enthusiasts to workers on the manufacturing floor, everyone's imagination is captured by the potential of 3D printing. Prototyping, spare parts creation, art delivery, human organ creation, and even mass product production are all being targeted as current and potential uses for the technology.
ABI Research, a firm based in the UK that specializes in analyzing global connectivity and other emerging technologies, estimates there will be 40.9 billion active wirelessly interconnected “things” by 2020. The driving force is the usual suspect: the Internet of Things.
Just in time for Earth Day, chemicals leader Bayer MaterialScience reported from the UTECH Europe 2015 polyurethane show on programs and applications using its materials to help reduce energy usage. The company also gave an update on its CO2-based PU as that eco-friendly material comes closer to production.
Solar and wind energy are becoming more viable as a source of energy on the electric grid. For decades, the major drawback to solar and wind was that they’re temperamental. A cloudy day kills solar and a still day renders the wind turbines useless. Automation tools, however, are providing a path to help these renewables become practical.
In honor of Earth Day, the National Security Agency has launched the STEM Recycling Challenge in Maryland schools to encourage kids to think about where the garbage they throw out every day actually goes. The agency has also introduced “Dunk,” a muscular blue cartoon recycling bin wearing shorts and sneakers.
Focus on Fundamentals consists of 45-minute on-line classes that cover a host of technologies. You learn without leaving the comfort of your desk. All classes are taught by subject-matter experts and all are archived. So if you can't attend live, attend at your convenience.
