Three-phase electric power is a system where three currents run along the same circuit at slightly different times. Although the frequency of each current is identical, they vary sinusoidally. The ...

In power distribution systems, three-phase transformer configuration directly impacts system reliability and load management.

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 ...

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 ...

One of the more popular three-phase electrical services supplied to medium-size commercial buildings is the Wye or Star configuration transformer. The name comes from the transformer’s secondary ...

A motor control IC is a convenient way to implement custom motor drive algorithms such as the single-phase induction motor (SPIM) control. A generalized control algorithm, implemented and tested in an ...

Keep in mind when reading any article about electrical theory or application that it only scratches the surface of the topic. You can dedicate years of your life to understanding electrical theory 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 ...

The flux-oriented control (FOC) is a commonly used technique for three-phase electric motor control application. Here, the applied voltage pattern is defined using the space vector modulation (SVM) ...

The average efficiency of an internal combustion engine in real-world operation is measured at around 20 percent. 80 percent is lost as waste heat, of which only a small proportion is useful in winter ...
