Regenerative power drives and harmonics: they sound complicated, but it’s easy to see why they’re an electro-mechanical wonder in our every-day lives. For example a smooth ride on an elevator or escalator means the motor behind the scenes was re-generating its own power. How? When moving us up, the motor loads with energy, and when…

“We were then satisfied that, with proper lubrication and better adjustments a little more power could be expected.” — Orville Wright Bearings can be found in most anything that rolls, from skateboards to rocket motors in billion dollar space shuttles. When expensive motors fail, the results can be catastrophic. Electric Motors also keep industry in…

Severe Duty Electric Motors: IEEE 841 Then and Now When NEMA established IEEE 841 in 1986, “rugged duty” motors could simply mean motor parts were cast iron or coatings and shafts were constructed to resist moisture and rust. Each motor manufacturer defined “severe duty” motors differently. This left users without a measurable standard to specify…

Electrical motors might be called the “quarterback” of industrial activity. Intelligent motor protection relays can be considered the protective defensive line for monitoring, calculating and communicating potential overcurrent or overload conditions. Motor protection is used in residential (e.g., HVAC), commercial, and industrial facilities. Electrical professionals need to thoroughly understand the basic principles of motor protection…

  High Bay (HB) lighting fixtures are getting facility managers’ attention in industrial, commercial, manufacturing, gymnasium and other large indoor venues. These spaces at one time could be seen lit up with other lighting choices such as traditional HID (High-Intensity Discharge) and fluorescent high bays. In recent years, HB lighting fixtures have stolen some of…

High Bay LED Lighting, Low Cost of Ownership Dialight’s Vigilant is a high-output LED High Bay Light Fixture and an ideal HB replacement for less efficient 1,000W traditional HID fixtures. Dialight’s Vigilant high bay fixture is a groundbreaking innovation shining 125 lumens per watt at half the power consumption of standard HID lighting. The Vigilant LED HB fixture delivers about…

Electrical motors are the heart of production… quick disconnects increase production. Motor lead quick disconnects allow for fast connecting and disconnecting of reliable motor lead connections, facilitating motor maintenance and repair or diagnostics and testing. Thomas & Betts Blackburn KUBE Motor Lead Compression Disconnects reduce labor time by 50% versus conventional disconnect methods, according to a T&B. This increases…
