Infinitum, creator of the sustainable air-core motor (earlier post), has extended its Series E with $35 million in funding from Marunouchi Innovation Partners and Rice Investment Group. The additional funding brings the company’s total Series E funding to $220 million, and will be used to scale the company to meet customer demand and drive decarbonization.

Infinitum’s air-core motor systems can sustainably power energy-intensive applications used in data centers, hospitals and buildings, as well as logistics, manufacturing and industrial facilities with less electricity, carbon emissions and waste.

When compared to traditional motors, the Infinitum motor system consumes 10-65% less energy, is 50% smaller and lighter and uses 66% less copper. Infinitum’s motor systems have an integrated variable frequency drive and can be customized to meet an application’s specific power and torque requirements to reduce strain on the electric grid by drawing less power.

Infinitum motor systems use fewer raw materials in manufacturing and modular design allows for motors to be easily serviced, repaired, remanufactured or recycled to keep motors in service and out of landfills.

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 CO₂, according to the US Department of Energy.
