Providing up to 8A of continuous current, Performance Motion Devices', ION Microstepping Digital Drive targets semiconductor as well as medical, scientific, automation, industrial and robotic applications. In addition to high performance motion control, the unit provides network connectivity and amplification in a fully-enclosed module for dc brush, brushless dc, or step motors. The drive supports two-phase bipolar motors and can automatically switch between user-defined current modes. Communications are handled by either asynchronous serial (RS485) or CANbus network. The unit handles 8A continuous and 15A peak current, but an optional heatsink increases the current capability. To complement the selectable profiling modes that include S-curve, trapezoidal, velocity contouring and electronic gearing, the unit operates at 40 kHz PWM frequency with 102 µsec servo loop rate and has an advanced PID filter with velocity and acceleration feedforward.

Wal-Mart will hold its second Made in the USA Open Call July 7-8, at its headquarters in Bentonville, Ark. The event will be a repeat effort by the world’s biggest seller of consumer goods to increase the amount of US-made products it sells in Wal-Mart stores, in Sam’s Club members-only wholesale outlets, and on walmart.com.
From design feasibility, to development, to production, having the right information to make good decisions can ultimately keep a product from failing validation. The key is highly focused information that doesn’t come from conventional, statistics-based tests but from accelerated stress testing.
There’s a good chance that a few of the things mentioned here won't fully come to fruition in 2015 but rather much later down the line. However, as Malcolm X once said, "The future belongs to those who prepare for it today."
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.
