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

For IGBTs, the on-state voltage drop is a critical specification to consider. This drop includes both the diode drop across ...

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 ...

Art. 430 provides the requirements for motors. But at a whopping 27 pages, it is the largest article in the National Electrical Code (NEC). From a technical standpoint, it is arguably the most complex ...

Early incarnations of the electric motor first appeared in the 1740s through the work of Scottish Benedictine monk and scientist, Andrew Gordon. Other scientists such as Michael Faraday and Joseph ...

Somewhere in most engineering educations, there’s a class on induction motors. Students learn about shaded-pole motors, two-phase and three-phase motors, squirrel cage motors, and DC-excited motors.

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 ...

Boutique Swedish automaker Koenigsegg recently unveiled the production version of its Gemera hypercar. It’s a hybrid, powered by two available combustion engines as well as a single, powerful electric ...

Innovative Swedish boutique carmaker Koenigsegg has revealed a new 6-phase electric motor for its four-seat Gemera supercar that establishes new benchmarks for power density. The Dark Matter motor ...
