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.
