One of the hidden complications of upgrading grain drying and handling systems is providing enough electricity to power the new larger electric motors. Electric motors that are larger than 15 hp ...

Many older industrial facilities use single-phase, oil-filled transformers made for pole-mounting but installed at ground level to create 3-phase power distribution systems. Usually, primary and ...

Home machinists can often find great deals on used industrial equipment, and many a South Bend lathe or Bridgeport milling machine has followed someone home. Then comes the moment to plug it in, and ...

In the original version of this article, the second figure contained an error. The image has been updated. It’s important for engineers to have a good, working ...

Having both 3-phase and single-phase loads can be challenging when trying to balance the voltages at a facility. It’s possible that during a facilities operation, one phase can be lightly loaded ...

The major drawbacks of conventional diode or thyristor rectifiers are overcome by active power factor correction; this further provides additional benefits. Operating principles and features of single ...

Variable frequency drives (VFDs) are used in many industrial applications to improve energy efficiency and provide precise control over electric motors. By adjusting the frequency, voltage and current ...

BridgeSwitch ICs provide a motor current output signal that maps the current passing through the low-side FREDFET. An internal sense-FET provides lossless current sensing. The solution is suitable for ...

Electric fans commonly use low-cost AC motors built around capacitors, which now increasingly demand replacement due to high power consumption. However, while three-phase brushless DC (BLDC) motors ...
