Infinitum and Alliance Resource Partners, L.P. Announce Agreement to Bring Highly Efficient, Reliable Motor Technology to the Mining Industry

This new innovative motor system will create lighter-weight, high performance mining equipment and help electrify heavy industry.

TULSA, Okla.--(BUSINESS WIRE)-- Infinitum, creator of the sustainable air-core motor, and Matrix Design Group, LLC (“Matrix”), a wholly owned subsidiary of Alliance Resource Partners, L.P. (“ARLP”) and leading safety and productivity technology provider for mining and industrial applications, today announced an agreement to jointly develop and distribute high-efficiency, reliable motors and advanced motor controllers designed specifically for the mining industry.

Under the agreement, Matrix will integrate Infinitum’s smaller, lighter motor technology into mining equipment of ARLP's operating subsidiaries to provide performance validation in production environments for the jointly developed products. In addition to supporting installations at ARLP operations, Matrix plans to offer the products to third-party mining customers around the globe.

Infinitum’s patented motor technology will replace traditional, heavy iron-core motors with a motor system that is 50% smaller and lighter, uses 66% less copper, and consumes 10% less energy, and is expected to offer mining companies and equipment manufacturers a more efficient, reliable alternative.

“Working with ARLP and Matrix expands Infinitum’s ability to sustainably power heavy machinery with our lightweight, power-dense motors that use less energy, material and waste,” said Ben Schuler, founder and Chief Executive Officer, Infinitum. “We’re excited to join forces with a mining leader like ARLP to make a greater impact towards electrifying and decarbonizing heavy industry.”

Over the past 15 years, Matrix has become a leader in collision avoidance and proximity detection technologies, providing safety and productivity solutions for ARLP and many other mining companies, while extending its reach beyond the U.S. and to other industrial applications. This agreement builds upon that success and enables the development of proven products that provide technological advancements in support of rapidly expanding customer needs.

Joseph W. Craft III, ARLP Chairman, President and Chief Executive Officer commented, “This collaboration with Infinitum represents a natural progression and extension of our strategic investment in the company. We believe their groundbreaking motor technology will bring much needed innovation to the mining industry by delivering more efficient and higher performing production equipment, which will enable companies such as ours to improve mining processes, reduce operating costs, and boost productivity.”

Infinitum, ARLP, and Matrix have collaborated since 2022, when ARLP made an initial investment in Infinitum as part of the company’s Series D funding.
