Video: Yaskawa talks Variable Frequency Drives
Control Engineering Content Manager Peter Welander talks with Yaskawa's Manager of Marketing Communications Neil Koepke about the benefits of using variable frequency drives. While Welander visited the Americas headquarters for Yaskawa in Waukegan, Illinois, Koepke showed three different types of motors in a demonstrator that was built jointly by Yaskawa and the Milwaukee School of Engineering. The demonstrator's first cell shows a constant speed across-the-line motor and its flow control is varied with an outlet damper. In the second cell, a three-phase motor, which is constant speed, operated across-the-line, uses a inlet-guide vein for the flow control means. In the third cell, a variable frequency drive operates a three-phase motor and the drive itself controls the airflow in its environment.

2012 Salary Survey
In a year when manufacturing continued to lead the economic rebound, it makes sense that plant manager bonuses rebounded. Plant Engineering’s annual Salary Survey shows both wages and bonuses rose in 2012 after a retreat the year before.
Average salary across all job titles for plant floor management rose 3.5% to $95,446, and bonus compensation jumped to $15,162, a 4.2% increase from the 2010 level and double the 2011 total, which showed a sharp drop in bonus.
