Linear motor replaces ballscrews

HyCore linear motor combines features and performance of high-force brushless linear motors with the cost advantage of open-loop linear stepper motor technology. Using magnets only in the primary (forcer) reduces cost. Linear motor benefits include zero backlash, high efficiency, unlimited travel, fast velocities, and high accelerations. Secondary (platen) has no magnets, can be cut to fit the application, and does not attract ferrous particles.

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.
