Electric motor power efficiency has taken center stage. Individuals, corporations, and governments are increasingly interested in saving power, now that technology can make it possible and economy ...

The need for the current waveform to track the voltage on a three-phase power system leads to a second set of requirements, in addition to those for a single-phase power factor correction (PFC) system ...

The motor calculations presented here apply to changing conditions of a blower motor when pulley adjustments are made. However, these calculations are useful wherever electric motors are used. These ...

Correctly installing capacitors at the terminals of your motors can lower reactive power requirements and increase system power factor. Induction motors are the primary source of rotary power in the ...

Here are the power and driver boards that [Miceuz] designed to control a three-phase induction motor. This is his first time building such a setup and he learned a lot along the way. He admits it’s ...

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 ...

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 ...

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 ...
