New Product Round-Up

Spring is a time for renewal. Here’s what some companies are nurturing.

Ah, spring. It means cleaning for some, taxes for others, but it’s universally a time of renewal. In the electromechanical industry, a few leaders have new products out. Let’s take a look at some of these as we prepare for fresh air and dare to repair.

Get ACTion. The great Theodore Roosevelt had a choice phrase in his early life: “Get action”.

When it comes to being active on the product market, and manufacturing devices that facilitate action, ACT (Akard Commutator of Tennessee) is consistently a presence. The Smoky Mountains outfit added to its well-known G-Force line recently with the addition of a new tightness documentation certification on all “high-performance” commutators—those with nameplate maximum speed greater than 1700 rpm, that is.

The Alcoa, Tennessee-based company has championed innovative methods of commutator testing since its founding in 1993, and continues to do so. Akard’s ACTive G-Force line diagnoses centrifugal force-conditioned commutators, doing so without relying on “subjective testing methods like century old “ring test” and/or the “click” of a torque wrench,” the company said in a recent press release.

“Bar lifting, brush chatter, and runout issues are a serious problem for any electrical apparatus repair/rewind project that can add thousands of dollars cost and eliminate all profitability from the bottom-line,” Akard continues. “We are excited to provide ACT customers with industry exclusive ACTive G-Force certified fully documented tightness on all high-performance commutators to eliminate any chance of “false-tight” scenario or subjective “test” resulting in horrific instability problems in the field. One particular high-performance commutator example that comes to mind is for a 1750 rpm rated mining application in which ACTive G-Force certified fully documented tightness verifies stability in excess of 6000 Gs of centrifugal gravitational force with zero bar movement, completely eliminating what had previously been a commonly occurring problem in the field saving the end-users many thousands of dollars annually.”

Shaft seal for screw conveyors. Who is the man, with that seal in his hand…Shaft!

Inpro/Seal announced the latest AM Solutions design, the AM CEMA shaft seal, developed specifically for CEMA (Conveyor Equipment Manufacturers Association) screw conveyors, in a press release sent to EA April 1. “Invented by Inpro/Seal in 2005, AM (Air Mizer) solutions are complete shaft seals that permanently protect against product loss and contamination on industrial processing equipment,” the Rock Island, Illinois company states. “By utilizing a positive air- or inert gas- purge, Inpro/Seal AM solutions shaft seals provide a non-contacting and non-wearing seal, lasting the lifetime of your equipment.”

Shaft movement and misalignment are common on screw conveyors. Traditional seals rely on dynamic contact to create a seal. Shaft movement creates frictional contact, causing the seal to wear or groove the shaft, leading to seal failure. Seal failure brings higher production costs, increased maintenance, environmental concerns and even unsafe working conditions.

The AM CEMA shaft seal utilizes a positive air- or inert gas- purge to create a barrier between the shaft and seal, eliminating product leakage and process contamination. Due to its unique, non-contacting design, the AM CEMA shaft seal has no wearing parts, requiring minimal maintenance or need for rebuild kits. To accommodate shaft movement, the AM CEMA shaft seal fully articulates to allow for radial run-out and angular misalignment simultaneously.

Data analysis wall charts for motor testing. The Snell Group has been conducting motor testing and training for almost two decades.

“During that time, we have used multiple test equipment’s to test tens of thousands of motor and motor circuits in most types of industrial and commercial facilities. We have developed comprehensive and innovative Electric Motor Testing Training and Certification Courses,” the Barre, Vermont-based company said in a press release March 28. “Our latest innovation is a culmination of years of expertise in the field of electric motor testing.” That’s a really solid preamble, if you ask me.

With a fundamental knowledge of motors and motor operation and theory, data analysis can still be quite complex, especially when multiple data sets must be correlated to determine a probable fault. Snell has therefore developed a De-Energized Motor Testing Data Analysis Wall Chart that it says will provide a single reference source to analyze almost every anomaly identified while conducting de-energized motor testing.

This resource is a laminated 3’ x 4’ wall chart packed full of motor analysis information. Designed to correlate with Snell’s motor training courses it is an invaluable data analysis tool for anyone that tests motors, regardless of instrumentation being utilized.

Customers and students can also take one of Snell’s motor training courses and get one as part of the curriculum! Click on the image (above right) to enlarge it, or on the link above to see a full-size PDF version of the image.
