New integrated brushless motor-drives
Dunkermotoren’s family of high performance modular brushless permanent magnet motors are driven by integrated servo motor drives
Dunkermotoren USA of Elgin, IL, developed a family of high performance modular brushless permanent magnet motors driven by integrated servo motor drives. The 2.95 inch (75 mm) squared high power density motors are available in 3 stack lengths. The family motor peak torque varies from 22.1 in.-lb (BG75x25), to 44.2 in-. lb (BG75x50), and up to 55.7 in.-lb for the largest model (BG75x75). Axial lengths are respectively 4.53-in. (115 mm), 5.51-in. (140 mm), and 6.50-in. (165 mm). The motors have modular construction, integral electronic drive and precision encoder with 4096 counts. The power electronics range of input voltages from 10 to 50 V dc, and delivers up to 50.

Annual Salary Survey
After almost a decade of uncertainty, the confidence of plant floor managers is soaring. Even with a number of challenges and while implementing new technologies, there is a renewed sense of optimism among plant managers about their business and their future.
The respondents to the 2014 Plant Engineering Salary Survey come from throughout the U.S. and serve a variety of industries, but they are uniform in their optimism about manufacturing. This year’s survey found 79% consider manufacturing a secure career. That’s up from 75% in 2013 and significantly higher than the 63% figure when Plant Engineering first started asking that question a decade ago.
