Motion systems application examples for ac drives
All ac drives (including those known as variable frequency drives or VFDs) must satisfy specific application demands. The most common of these ac drives differ from those typical for precision motion control found in robotics, semiconductor fabrication, certain types of machining, and medical instruments to output motion to sub-mm to µm and even nm scales. […]

Drive/motor combo cuts extruder energy usage by 9%
Recently, Emerson Industrial Automation was able to help Stål & Plast, a Danish extrusion specialist, improve its production processes by replacing three worn-out dc electric motors with Dyneo PM motors and a Unidrive M variable speed drive at the company’s extruder plant. Stål & Plast A/S of Denmark manufactures bench tray systems used in greenhouses […]
Omron launches compact + robust three-phase S8VK-T power supplies
Omron Automation and Safety (www.Omron247.com) introduces the 3-phase S8VK-T switching power supplies with robust design and construction that withstands harsh environments and provides stable operation over a wide-operating temperature range (-40°C to 70°C). The compact design takes up less panel space than other 3-phase power supplies and delivers 90% energy efficiency, which reduces heat build-up […]
How to handle imbalances from light loads on VFDs
by Daniel Peters, Drives Application Engineer, Yaskawa America Input current imbalances happen when a variable frequency drive (VFD) with a full-bridge rectifier operates under lightly loaded conditions. Here we explain what to do about it. One phenomenon that electricians often see after installing a VFD is measurable current imbalance on the input to the VFD […]
