Infinitum – the sustainable air-core motor creator – recently announced $185 million in Series E funding led by Just Climate with participation from Galvanize Climate Solutions and NGP. Existing investors, including Alliance Resource Partners, Rockwell Automation, Riverstone Holdings, Chevron Technology Ventures, Cottonwood Technology Fund, and Ajax Strategies, also joined in this round, bringing total funding to date to $350 million. The funds will be used to expand the company and increase production to meet customer demand and drive decarbonization in the industrial sector, one of the largest and hardest-to-abate emitters of greenhouse gases.
Motors are the largest single energy end-user, consuming 53% of electricity globally. In the US industrial sector, motors alone consume nearly 70% of the total electricity used to power numerous core industrial applications like compressors, pumps, fans, and material processing and handling equipment, according to the International Energy Agency (IEA).
But most motors today waste energy because they operate at a single speed. Since 30% of the growth in global electricity demand by 2040 is expected to come from industrial motors as the sector expands and shifts to electrification (Deloitte), adoption of higher efficiency. And variable speed motors in industrial applications is critical for reducing energy and emissions.
Infinitum’s advanced motors meet this challenge through a built-in variable frequency drive (VFD) that reduces energy usage by running the motor at lower speeds when possible. And the motor is 50% smaller and lighter, uses 66% less copper and no iron in the stator, and consumes 10% less energy than traditional motors. And Infinitum’s air-core motors, so named because the stator does not have an iron core, replace the copper-wound iron core found in traditional motors with a lightweight printed circuit board stator that is 10x more reliable. Manufacturing and servicing Infinitum motors is less carbon intensive than traditional motors, and the motor’s modular design allows components to be reused multiple times.
The implementation of advanced motor technology in the US industrial and commercial sectors has the potential to save 127 terawatt-hours per year (TWh/yr), translating into cost savings of $14.7 billion and reductions of 90.2 MMT of carbon dioxide, according to the U.S. Department of Energy. This is equivalent to the annual electricity use of all households in California and North Carolina combined.
To accelerate the adoption of high-efficiency, variable speed motors across the global industrial sector, Rockwell Automation and Infinitum are jointly developing a motor system that is compatible with Rockwell’s market-leading industrial automation solutions. And the resulting motor and low-voltage drive solution will be distributed through Rockwell, expanding the opportunity for global industrial sector clients to easily deploy a sustainable motor system and cut energy consumption, operating costs and material waste.
