Low harmonic ac drive

HR1018 is an 18-pulse ac drive that reduces the total harmonic distortion (THD) associated with drives that employ fewer pulses. Reducing THD minimizes interference problems in environments with sensitive electronic equipment and minimizes heating in motors, transformers, and wiring. The drive incorporates an integrally mounted 18-pulse transformer and features a comprehensive set of monitoring, maintenance, and protective functions.

Annual Salary Survey

After two years of economic concerns, manufacturing leaders once again have homed in on the single biggest issue facing their operations:

It's the workers—or more specifically, the lack of workers.

The 2017 Plant Engineering Salary Survey looks at not just what plant managers make, but what they think. As they look across their plants today, plant managers say they don’t have the operational depth to take on the new technologies and new challenges of global manufacturing.
