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.

In many engineering workplaces, there’s a generational conflict between recent engineering graduates and older, more experienced engineers. However, a recent study published in the psychology journal Cognition suggests that both may have something to learn from another group: 4 year olds.
Conventional wisdom holds that MIT, Cal Tech, and Stanford are three of the country’s best undergraduate engineering schools. Unfortunately, when conventional wisdom visits the topic of best engineering schools, it too often leaves out some of the most distinguished programs that don’t happen to offer PhD-level degrees.
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.
