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 ...

Today, compressor overheating is one of the HVACR industry’s most serious field problems. Compressor overheating is usually caused from high compression ratios. High compression ratios can be caused ...

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 ...

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 ...

Where three-phase power is unavailable or impractical, it’s single-phase motors to the rescue. Though they lack the higher efficiencies of their three-phase siblings, single-phase motors — correctly ...

Selection of replacement motors is usually straightforward if the ratings are equivalent. Sometimes, however, a different type of motor is necessary or desirable. For success in these cases, it is ...

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 ...
