CASE STUDY
ROTOCON Electrical Rotary Ground Provides Maintenance-Free 6,000A Solution for Battery Recycling Operations
CHALLENGE
A company that manufactures and operates rotary electrolyzers for recovering (plating) lead from spent lead acid batteries approached Meridian Laboratory with a unique and demanding application. Using breakthrough technology, their electrolyzers operate at ~6000 Amps, this high amperage is necessary to achieve efficient lead recovery and recycling. These electrolyzers operate in series, some can float as much as 80 VDC above ground. The company had been seeking an alternative rotary ground that could meet these higher demands while also eliminating costly maintenance.
All previous traditional rotary grounds delivered poor consistency in performance and reliability. These metal-on-metal rotary grounds were difficult to maintain and inevitably caused down-time due to poor performance and fluctuating electrical resistance.
Companies that require high-current rotary grounds with zero maintenance are pleased to find that all ROTOCONs are brushless. Meridian Laboratory’s innovative brush-free design ensures a clean and consistent noise-free electrical signal, that remains unaffected by speed, and requires no maintenance.
SOLUTION
Meridian Laboratory designed a drop-in replacement single-contact MC2F-6000 with two flanges, designed to meet the 6,000A requirement with 0.005mOhm (5µΩ) of resistance. The ROTOCON MC2F-6000 is engineered to withstand 100% duty cycle in continuous manufacturing and production processes such as these. The brush-free design eliminates all issues such as maintaining brush contact, application of conductive greases, and the elevated contact resistance associated with conventional brushed rotary grounds. With the MC2F-6000, the company receives a consistent ground, with zero noise or elevated contact resistance over time and revolutions, ultimately allowing for increased output and productivity.

ERG-10000 Update
After the success of this project, the customer identified a need for a unit that could handle 10,000 Amps. Meridian Laboratory designed and manufactured the ERG-10,000, a maintenance-free rotary ground that carries up to 10000A.

ROTOCON High Current Rotary Ground Series
Meridian Laboratory offers a full lineup of single contact, high current rotary ground clamps that all provide a consistent, maintenance-free contact unaffected by RPM or total number of revolutions. The ERG Series is available both in end-of-shaft and through-bore configurations in a range of amperage levels, dependent on your needs. For applications requiring high frequency and high current, Meridian Laboratory offers specialized versions to accommodate for temperature rise due to eddy currents.

Excellent service! We faced Meridian with a difficult part to make and asked for perfection. They took the challenge on … More and through repeated effort and determination, Vance and the team were able to get us the "perfect" product we needed. Although this was undoubtedly a frustrating project for all involved, they saw it through and proved Meridian Laboratory to be exactly the company we needed and want to work with in the future. Great work!

Adam and the crew at Meridian Laboratory were a pleasure to work with! Adam was extremely helpful, knowledgeable, and responsive. … More A slipring was purchased through Adam for the use of a university engineering capstone project, he was eager to help and very nice throughout the entire process to ensure our needs were satisfied. The slipring shipped and delivered in a timely manner and once the unit was received, all expectations were exceeded. The fit and finish of the slipring was great, and it performed exactly as expected. I highly recommend Meridian Laboratory if you require the use of a slipring, as I cannot say enough good things about the team over there and their American made products

We contacted Adam Ellingson of Meridian Laboratory about acquiring a high-speed 3 channel ROTOCON slip-ring for our university … More capstone project. Mr. Ellingson was gracious enough to provide our team with a 6 channel slip-ring that performed excellent out of the box. The slip-ring assembly feels precisely machined and spins true with little mechanical resistance. It was the perfect product for testing our axial flux generator design and the extra channels came in handy. We appreciate the ease of mounting and excellent support from Mr. Ellingson.
