Infinitum Electric, a creator of strong, lightweight, and cheap electric motors with their own patented circuit board stator technology and control systems, recently finished a $1.8 million Series A funding round that was led primarily by Cottonwood Technology Fund.
To date, Infinitum has received a total of $2.7 million in funding, and plans to leverage the new financing to launch an HVAC-specific, fully-integrated motor. Infinitum will also use the new funding to increase research and development efforts for applications in the Electric Vehicle and Oil and Gas markets.
Infinitum Electric says that its PCB stator technology and control systems, with five patents and eleven patents pending, provide superior performance in the electric motor industry with a cost advantage over traditional motors. Among the benefits of the technology:
Removal of the conventional laminated stator core significantly reduces core losses, decreases cogging and torque ripple and increases efficiency. Identical copper conductors allow electrical losses to be easily controlled and provides the highest power density by optimizing copper layout.
Copper conductors are fully insulated and provide the entire coil with an equal coefficient of thermal expansion. The continuous coil design limits internal connections and increases life expectancy. In the absence of mechanical interference, this insulation method and stator design is almost indestructible, the company says.
Wire windings and iron laminations are eliminated by etching copper conductors into a printed circuit board. Weight reduction on the component level is as high as 90% and the machine level can be up to 50% lighter weight.
