Timing of surgical referral for pediatric atrioventricular septal defect (AVSD) is dependent on the subtype of AVSD with repair in infancy (3-6 months) for complete AVSD and repair during toddler ...

Improperly terminated VFD cables can generate up to 60 amps of common mode current spikes through facility ground grids, damaging unconnected control and communication equipment. Most electricians ...

The low-voltage variable speed drive (VSD) allows variable control instead of fixed-speed operation. These days, VSDs can reduce energy consumption by up to 30% on average—and as much as 80% in ...

Watch a major upgrade: a motor swap on a big belt grinder to install a powerful 4.4kW (5.9hp) three-phase motor with VFD speed control. Learn about SFPM calculations and how belt grit choices affect ...

Abstract: The failure rate of motor insulation in variable frequency drive (VFD) motors is higher compared to that of mains-fed motors due to the increased electrical stresses inflicted by the VFD. At ...

No prior successful cases of VSD corrections have been documented in veterinary literature. A private animal hospital in South Korea recently reported that its cardiac surgical team has successfully ...

Frank DeStefano, MD, MPH, was there in the early days of the CDC's Vaccine Safety Datalink (VSD), which first came online in 1990, when the agency convinced four health maintenance organizations (HMOs ...

Cobra’s DS-Adapt LS Long Drive head is what happens when engineers stop asking, “should we?” and just go full send. During a recent trip to Cobra HQ in Carlsbad, I had the chance to test the new ...

A grouping of Mitsubishi Electric’s AC drives or variable frequency drives (VFDs). In the competitive landscape of machine design, engineers in food, pharmaceutical and manufacturing sectors face the ...
