This 47" diameter 468 bar glassband commutator has solid risers and operates in a 3200KW GE motor. Glassband commutators differ from V-rings as the retaining force is on the exterior via the resiglas bands. The material is made from high tensile glass yarns laid parallel and bonded with fully catalyzed thermosetting resins. The commutator is banded to an OEM specified number of wraps applied at >600 pounds. Once installed on the armature the bands should be coated with Viton® and/or Limitrac® which seals the seams between copper and banding. This ensures that carbon cannot infiltrate behind the bands, where they can burn from the inside out causing catastrophic failure.
Thursday Thoughts:
As I was sitting here at my desk (and yes, the photo is cropped so you can’t see the mess), I realized that how we communicate is more important than ever. Leadership doesn’t have a look, it has a sound. As business owners, being open brings a renewed sense of strength to universally stressed employees, customers, and everyone, really.
My people worry. Yours do, too. They worry about the future…tomorrow, next week, next year. They get caught up in their day-to-day, and it’s natural. When we can bring them the big picture, it changes their perspective. The other day, we had a quick whole company lesson (outside) in Business 101. Cash keeps a company healthy. Customers paying us are stretching out payments. We are doing the same, but less so as we commit to our treasured local and key vendors. Paychecks are deposited. Insurance is paid. Are performance reviews overdue even though deserved? Yes. But merit increases need to wait right now while we ensure that everything is in place to be sure that everyone has jobs. Sometimes, it’s that simple. As an employee, you may not agree with my decisions, but I will always endeavor to help you understand why I made them. And I am human, so there will be mistakes, but not for lack of caring.

Thursday Thoughts: What do your people want most right now?
Thursday Thoughts: What do your people want most right now? Mine wanted haircuts. And beard trims. Who’d have guessed? While checking in with the guys on a regular tour around the shop floor, it seemed odd to me that in three separate conversations, the main comment was, “Man, I need a haircut.” I have to admit, It never actually occurred to me that these guys gave their hairstyles much thought. That’s not a criticism, more of a revelation.
What else do we forget to think about? We know, as leaders, that everyone has things going on personally that impact their lives and work. But, if once in awhile, we hit on a common thread within a group, is it not a great opportunity? It turned out to be the perfect way to show my appreciation for this amazing team. Haircuts for all who wanted them. Outside on the loading dock, masked, by a professional. One after another they cycled through and headed for home with one less thing to worry about.
Consider your joints.
In inserted riser commutators, the connection between the riser and the copper bar is critical both mechanically and electrically.
Silver braze, while more expensive than the silphos traditionally used, solves the problem. In some environments, H2S (hydrogen sulfide) reacts with the phosphorus in standard silphos joints and causes increased resistance and decreased stability. In paper, metals, food processing, phosphate and gas plants, H2S is often the culprit, and the problem is exacerbated when the motor is subjected to higher performance standards than in the past.
Ask us about the optimal material choices for your application, and we will steer you straight to the solution. We are ICC, and improving commutators is our only job. Industry depends on it.
Did you know?
The very material we use day in and day out in the electro-mechanical industry has properties we don’t think about. Copper has long been known for its infection killing properties, the knowledge of which dates back to as early as 3200 B.C. and record of which dates back to c. 1700 B.C..
The free electron in its outer orbital shell of electrons, which also makes copper such a good conductor, allows the ions to actively seek and then destroy the DNA and RNA in bacteria and viruses.

People First
Owning a business is first and foremost a commitment to the people who work there and the people we serve. We have taken drastic measures in juggling shifts, disinfecting professionally, adding paid sick leave, and guaranteeing to every employee that no matter the hurdles, I will personally make sure that not a single one goes without a paycheck, without health insurance, or without anything else that they and their families have come to rely on. Is it easy? No. But in a world where stress levels are at an all-time high, anything we can do as business owners to help take some of the worries off the list, is a win. The people of ICC are talented, committed and incredible human beings. And what’s more, if we answer your phone call, help solve a problem, build you a commutator, or place an order with you, you become one of us. We are here, we are busy, and we will always go above and beyond. Count on us. We are ICC.

Why is oven baking time such a hot issue?
Time is money...is the short answer.
Do you expect to season your commutator while it is operating? Probably not.
That’s our job. Thorough baking cycles are imperative to stability in operation. Mica v-rings aren’t completely cured until a comm is fully at temperature (350° F) for a minimum of 4 hours. But, there’s more. Copper and steel expand and contract at different rates and by different amounts.
Full thermal cycling ensures that none of this has to happen when your production is on the line.
We are ICC, and improving commutators is our only job.
Our industry depends on it.

Extension Banding
We've said it before but it's worth repeating.
Good extension banding is absolutely critical to maintain the life of your comm. Banding with gaps and cracks allows for carbon to infiltrate, ultimately leading to shorts or even worse, complete failures. It's important to inspect the banding from time to time as well as coat the banding and the front face of the bars with Viton or Limitrac.
If you have any questions ICC is always here to help, even if you didn't buy your comm from us
Segment Pack Bore
When you have new tooling that literally makes the segment pack bore shine like a piece of art.
Mica Matters
Mica matters. This segment mica is made of alkyd vinyl with low resin content. Mica acts as the insulator between each copper bar to avoid shorting out the commutator. At a dielectric strength of 600V per mil (24,000 V bar to bar on an average comm), it can handle just about anything. ICC Materials
Commutator Wrapped Caps
What you see here is a beautifully wrapped front cap on this large glassband commutator. There are various reasons for wrapping the cap but generally speaking, the purpose is insulation from an EQ ring.
Undercutting: Glassband Commutator
Glassband comms come in all shapes and sizes. Here, this tall, skinny comm is receiving pre-undercutting. Many clients choose to have ICC do the pre undercutting to save hours on their shop floor. And while he looks great in green that tape is in place to protect against any contamination. It will be removed, tested and QC'ed again before heading over to have risers straightened. https://iccinternational.com/building-process
News Sentinel Article: Women CEOs in East Tennessee
‘I have made a discovery. When interviewed while on vacation, the result is far more personal, and maybe just a little more human than when I answer the very same questions while sitting at my desk. When reading it with as much objectivity as I could muster, I found it to be an interesting result, but it certainly gets to the heart of what it’s like to be a part of ICC and it’s culture. Thanks to Brenna McDermott for taking the time to delve into life as a CEO from women’s perspectives.’ - Laura Lyle, President and CEO
Arconic Foundation Internship Program of Blount County
We are proud to be a continuing partner of the Arconic Foundation Global Internship Program of Blount County and wish all the graduates tremendous success in their future careers. And thank you for giving ICC the opportunity to be a part of this program, we too learn a lot from interacting with the students.
V-Ring Torque Values
Please note: when checking bolts on a v-ring comm, standard fastener torque charts can not be used. Over tightening a comm can result in bent dovetails, in turn leading to loose bars. If you have a question about the proper torque for your specific comm, please don't hesitate to ask. ICC is here to help, even if you didn't buy your comm from us.
Materials Matter
The commutator is the heart of a DC motor. While it doesn't take a large variety of materials to manufacture a comm the choices we make couldn't be more critical. With fewer DC motors in operation today, big DC required to perform better than ever. Did you know that silphos braze materials can actually cause issues with connectivity as the joint breaks down in certain applications? Instead, 38% silver braze will eliminate this risk and provide a stronger connection over time, both mechanically and electrically. The right material and design can prolong the life and performance of your commutators. https://iccinternational.com/building-process
DC is here to stay.
So maybe that’s not a statement you hear every day, but hear me out. As the DC motor market shrinks, where they are still used, the performance standards are higher than ever. Big DC must be engineered to support improved motor performance, and withstand more rigorous operating conditions. The commutator is a huge contributor to this as a major component, and ICC is the company worldwide that is continually working to improve the processes, materials, and the finished product. Watch our most recent video from the EASA International conference to learn more, and tell us what you think. I, for one, am committed to improving the health of this industry not just in North America, but around the world. Please join me. Laura Lyke, President & CEO
