Soft starter uses less power
Intelligent Technologies soft starter uses a 24-V dc control power and is 30-80% smaller than other industry offerings. It uses microprocessors and separates the control and logic circuits to reduce the control power requirements of these devices. Its design integrates both the bypass contactor and overload relay functions into one unit. Eaton Corp.; www.cutlerhammer.eaton.com

Soft starter regulates torque
Simplified motor soft-start is a low horsepower, three-phase product that contains up to 70% fewer electrical components than the typical unit. It regulates starting torque without limiting starting current or running speed by applying reduced voltage to only one phase initially. It is available from 13 hp, 208-V ac to 30 hp, 408-V ac.

Family of motors rated for VFDs
Blue Chip severe-duty, explosion-proof motors are rated for variable and constant torque variable frequency drive (VFD) applications. Motor features include epoxy paint, corrosion resistant hardware, and oversized rotatable conduit box. The insulation system uses corona resistant magnet wire to resist voltage spikes. Low loss laminations minimize temperature rise and increase motor life. Marathon Electric Mfg. Corp.; www.marathonelectric.com

Annual Salary Survey
Before the calendar turned, 2016 already had the makings of a pivotal year for manufacturing, and for the world.
There were the big events for the year, including the United States as Partner Country at Hannover Messe in April and the 2016 International Manufacturing Technology Show in Chicago in September. There's also the matter of the U.S. presidential elections in November, which promise to shape policy in manufacturing for years to come.
But the year started with global economic turmoil, as a slowdown in Chinese manufacturing triggered a worldwide stock hiccup that sent values plummeting. The continued plunge in world oil prices has resulted in a slowdown in exploration and, by extension, the manufacture of exploration equipment.
