For ICC, the annual International EASA Conference is a way for us to thank so many of the people who help make us successful. We were so pleased to see so many of our customers and vendors in Tampa, many of whom have become friends over the years. We would like to sincerely thank all the hardworking EASA employees and volunteers for another successful conference. This forum which brings a multitude of partners together facilitates so many opportunities for which we are truly grateful. ICC is so pleased with our success from the show that we are already making plans for our 2018 participation!

Steel Shrink Commutator Construction Overview

1 of 5 - Steel Shrink Ring Commutators
Here we have received the comm assembled to the armature. We then tear it down to collect interior and exterior dimensions. This comm will be rebuilt on the armature shaft, as opposed to most commutators which are assembled to a hub with caps then installed on the armature shaft back at the motor shop.

2 of 5 - Steel Shrink Ring Commutator
This is the segment pack that has been compressed under significant tonnage, banded and cured. The copper and mica are so tight as a result of this process, that the segment pack behaves like a single piece of metal (picture a collector ring). It will grow symmetrically when heated, which then allows ICC to install the segment pack to the mica wrapped armature, with significant retained fit to the shaft.

3 of 5 - Shrink Ring Progress – this compressed segment pack has been installed to the armature shaft. Designed with complex tapers on the bore of the segment pack and the OD of the shaft, the unit retains all the required fit and is ready for the next steps. Of interest, GE and Westinghouse Steel Shrink Ring designs are very different, and require a whole different set of process steps and expertise.

4 of 5 - Cont. Shrink Ring Progress – Can you guess what RPM this 15” diameter commutator operates at? Like glassbound commutators, external steel shrink ring comm segment packs are retained on the OD (unlike v-ring comms which are held together internally). Forged steel rings need to be fully insulated from the copper, as well as installed with significant retained fit to ensure tightness which hold up under instantaneous acceleration and high rpm. This process is one of the most finicky of all, and requires years of experience to master.

Isn’t she beautiful? This careful crafted steel shrink ring commutator will run at 6000 RPM, and our customer can be confident that it will be fully electrically and mechanically sound, thanks to the expertise of our talented people.

Checking Skew

An integral part of the comm building process is checking the skew. After all the bars and mica are stood up into a segment pack we check the skew to ensure the bars are straight and not leaning to either side. It's a tedious process and takes a trained eye and patients to look at each and every bar individually.  It's a step that can not be skipped because if a bar is out of skew it will cause major problems throughout the process and the comm would then need to be rebuild from the beginning. 

ICC Machinists

Ernie, Brent, Rick, Ben and Jerry

Ernie, Brent, Rick, Ben and Jerry

These guys are like artists, they can take a piece of raw steel, bronze or G10 and machine it into caps, cores, slip rings, buttons and more. At the center of every commutator is a steel core. That core provides stability and strength to the segment pack, exactly how we like to look at our machinists. Working together with our front end production team they support each other, jumping in when they need a hand or a second opinion. 
Becoming a skilled machinist takes years of experience, between these 5 guys there are well over 150 years of knowledge. These machinists read and execute prints, they know what they are doing, each comm and slip ring is given individualized attention so when a machinist recommends an improvement it's taken seriously and often implemented.

Thank you guys for your dedication, hard work and attention to detail.

THE NAKED TRUTH... Paint can cover up a lot.

ICC International Glassband Commutator

ICC commutators are stripped down to show we have nothing to hide. You get perfect banding and beautifully sealed edges. Commutators that can stand before you ... naked, in fact. Your coatings will adhere better, and you never have to wonder about what you can't see. With ICC commutators, beauty isn't only skin-deep, but it's a good place to start.

ICC industrial commutators are crafted in small volume by experts using the highest quality raw materials available. Contact your ICC representative today.

ICC International Banding Commutator

Note: If you do need a commutator painted for a specific application, let us know and we'll take care of it.

Extension Banding and why it's CRITICAL

Check out this image of bad banding versus good banding.  See all the gaps and holes? 

Those tiny little slits between the banding and the steel put this commutator (on the left) in a vulnerable position. The fine particles of carbon that come off the brushes find their way into any little gap or hole.  Enough contamination will lead to a short or even worse, a failure.  To get the most life out of your commutators check the banding frequently and if needed replace the banding.  

ICC is more than happy to help. Call or email anytime if you have questions. We can walk you through what to look for and even guide you through the process, we'll even tell you exactly what products we recommend using.

Should you band the outboard end of a v-ring comm for stability?

No. Although this is a popular consideration when finding a commutator with high bars, this field fix can easily cause additional problems.

High bars are typically the result of one of these four causes

  1. Overheating – caused by current fluctuations or a stall condition. This causes the copper to swell, typically in an identifiable pattern, appearing as high bars.
  2. Bent dovetails – caused by over tightening the commutator as part of routine       maintenance.
  3. Loose commutator – typically the result of insufficient thermal cycling in closings, or bolts having backed off over time.
  4. Knocked or tapped bars – which have been machined smooth, but have then raised in operation as the dovetail re-seated itself due to centrifugal force.

Repairs for these situations are as varied as the causes, but banding the outboard end is not a solution.

In v-ring commutators there is a designed gap between the steel cap and the copper bar on the 3ᴼ angle of the dovetail (see fig 1). This is included to allow differential expansion of the copper and steel in operation, and is a necessary design component.

By banding the outboard end, the gap is forced closed, effectively shifting the entire length of the bar and causing the riser end and center to lift in operation (see fig 2).  In addition, at the outbound end, the angles begin fighting for seating position, and the result is even more bar instability at this end.

Some commutators are designed with a band on the outboard end (see fig.3). This design incorporates a machined lip on the inside of the dovetail which rests against the steel cap. This maintains the gap, but prevents any bar movement in operation. 

Split Ring Manufacturing

ICC manufactures not only commutators but slip rings as well. Below you'll see some of the steps involved to create a new set of bronze slip rings with G-10 insulation. 

Before work can begin on the mill a program is designed by our engineers. After the program is working properly the slip ring is clamped center of the machine and the mill can locate the exact points of machining.

Final Step is assembly. In this case the steel hub was reusable, so it was sandblasted and painted back to like-new condition.

What's in your copper?

Is it Tough Pitch Electrolytic Copper, silver bearing like Alloy 116? Our copper has 25-30 oz. of silver per metric ton for maximum strength and heat resistance. If your manufacturer isn't using silver bearing copper, consider asking for the upgrade.

ICC prides ourselves on using only the best possible materials. Providing quality to our customers is what we bank our reputation on, cutting costs is not an option. We believe quality over lesser price will always win in the long run.
