Variable frequency drive for ultra high-speed motors, spindles
Amtech Drives Eazy Series Variable Frequency Drive system is designed to manage electrical currents for high-speed motors and spindles.
Amtech Drives Eazy Series Variable Frequency Drive system is designed to precisely manage electrical current for ultra high-speed motors and spindles, the Eazy system uses a proprietary PWM sinusoidal waveform.
This advanced PWM technology combines with 5th generation IGBT devices to create improved bearing and spindle life as well as production up-time, the company said.
The Eazy system reportedly provides complete control and protection to ac induction motors in the 40 hp to 1875 hp range.
“We call it Eazy because it makes the operators life easy with simple to use features and dependable, automatic performance. For its given markets, the Eazy Series is one of our best values,” said Amtech Drives CEO Dan Patel.
The feature rich Eazy system includes a new 5th-generation IGBT power inverter, a SVPWM control strategy, a power losses ride trough, a built-in energy meter, a slip compensation function, true overload and ground fault protection, and standard RS-485 modbus-RTU communications software, in addition to standard encoder built in.
“This is a system that earns its keep right from the beginning making it one of our highest return on investment products in our inventory,” said Dave Lawler, national sales manager for Amtech Drives.
Reportedly popular applications for the Eazy system include rayon spinning equipment, agitators, centrifuges, pulp and paper equipment, and air compressors.

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.
