Munich, Germany--Electric motors have undergone more change in the last ten years than the previous hundred. This is particularly true with ac induction motors. For example, users today can specify vector or inverter drives, as well as the convergence of both systems: sensorless vector control. Other emerging technologies include soft switching techniques and transient-resistant windings.
Computer models take over. Sensorless vector control blurs the distinction between inverter and vector drives. While open-loop inverters are relatively inexpensive, there is no method of feedback from the motor to allow
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.
