Now Available: Helwig Carbon’s Updated Carbon Brush Pocket Guide

Tracy Perkins — Thu, 17 Jul 2025 16:32:19 +0000

Helwig Carbon Products, Inc. Updated Their Carbon Brush Pocket Guide.

Carbon brushes are used in motors and generators to conduct electricity between stationary (armature or stator) and rotating (rotor) parts of electrical machines. This transfer of current is essential for motor or generator operation.

The guide will help you identify carbon brushes in order to buy replacements
Provide best practices for installation, use, and replacement of carbon brushes
Offers guidance for troubleshooting common problems

And if you are working in a remote location without cell service or internet access, the guide is small enough to store on your phone or carry in your pocket.

Helwig Carbon BPK — Say Goodbye to Arcing, Fluting, Burnt Grease, and Bearing Failure

Tracy Perkins — Thu, 05 Jun 2025 11:49:00 +0000

Motors driven by Variable Frequency Drives (VFDs) are susceptible to damaging electrical discharges that seek the path of least resistance to ground, which is typically through the motor bearings. When these currents pass through the bearings, electrical arcing takes place leading to fluting, pitting, burnt grease, noise, vibration, and eventual bearing failure.

Helwig Carbon’s Spring Fatigue Test for Hydro Generator Applications

Tracy Perkins — Wed, 04 Jun 2025 11:31:00 +0000

For hydro generators, the industry had a rule of thumb to keep the total runout on the slip rings below 0.010 in. (0.25 mm) for good brush and spring life. Staying below 0.010 in. (0.25 mm) runout has been difficult, so Helwig was challenged by their customers in the hydro industry to determine the actual requirement for total runout. The fatigue life for a constant force spring in a brush holder is very difficult to determine analytically. Therefore, we conducted a spring fatigue cycle test that simulates . . . to read the full article click the image below.

Tracy Perkins — Wed, 28 May 2025 11:00:00 +0000

The Helwig BPK-SB bearing protection kit for WEG Motors provides ultra-low resistance path to ground damaging shaft currents. The long-lasting silver graphite brush provides up to 10 years of protection from EDM damage under normal operating conditions. The kit handles common mode and high frequency currents with ease. The durable brash body is designed to withstand harsh applications. It maintains positive spring force for consistent contact, even in contaminated environments. The kit comes with an industrial strength, durable mounting bracket.

Helwig Carbon’s Bearing Protection Kits

Tracy Perkins — Tue, 27 May 2025 11:00:00 +0000

Helwig’s BPK Bearing Protection Kits typically reduces shaft voltage to less than 1 V at frequencies greater than 1 MHz. They use highly conductive silver graphite brushes instead of carbon brushes. They provide the lowest resistance path to ground. Their stock kits fit most motors and multiple shaft sizes. They are easy to install. Their red retaining clip helps determine the correct kit mounting height. The internal mount options avoid exposure to outside and contaminated environments.

Mounting hardware for the BPK kits is sold separately.
