Motor insulation protects against voltage spikes
IRIS electric motors with inverter-rated insulation systems withstand the voltage spikes that result from the use of IGBT-type pulse width modulated inverters.
IRIS electric motors with inverter-rated insulation systems withstand the voltage spikes that result from the use of IGBT-type pulse width modulated inverters. The system for three-phase motors 1 hp and larger, plus other ac motors in adjustable speed drive systems, includes specially formed phase insulation, cushioned and sleeved connections, and stators dipped in high-temperature varnish.

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.
