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 ...

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 ...

Compressor overheating is one of the industry's most serious field problems today. Compressor overheating is usually caused by high compression ratios. High compression ratios can be caused by a ...

There are several reasons to use a three-phase inverter to run a single-phase induction motor, including isolation from variable power grids, reduction of peak currents and elimination of the starting ...

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 ...

So you just spent three hours removing and replacing a motor that drives the feed to a robotic welder. You connected the leads exactly the way they were before you disconnected them. You properly ...

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 ...

NEC Electronics’ (distribution: Gleichmann Electronics) two new 3-phase control device families, V850E/IF3 and V850E/IG3, open up all kinds of new application possibilities. Key features of these ...

This solid-state thyristor (SCR) switch circuit is perhaps the simplest means of reversing a 3 phase motor. “Static” is a catch-all term that essentially means without moving (mechanical) contacts ...
