DHX Electric Machines, Inc. was founded in  2014 to commercialize the patented, proprietary micro-feature enhanced DwHX cooling technology developed in MayorLab at Georgia Tech.  DHX holds an exclusive worldwide license to manufacture, market, and sell electric machines incorporating Direct-winding Heat Exchange and Variable Density Micro-Feature Heat Exchanger technologies from the Georgia Tech Research Corporation.


Operations commenced in August 2014 on the Georgia Tech campus. DHX started earning motor development revenue right away with a multinational elevator company contract. After concluding an Angle round the company transitioned to a 20,000 sq.ft building in August 2015, in Braselton/Hoschton, Georgia, equipped with lean manufacturing assembly cells, CNC machine tools, custom production and testing equipment for motors sized up to 3000 kW.


DHX started selling Hawk 20, 40, and 60 beta prototype motors to micro-entrepreneurs & businesses in 2016. The Hawk motors have been deployed in military amphibious vehicles, electric motorcycles, autonomous agriculture platforms, electric race cars, boats, yachts, academic labs, eATVs, golf carts, and electric utility vehicles. 

The PEREGRiNE series P20, P40, P60 was developed in 2020 and released in 2021 as the next generation of low voltage motors incorporating technology from custom product development contracts. High voltage KESTREL K20, K40, K60 motors for industrial applications were developed and released in parallel with the PEREGRiNE series. Batch manufacturing started early 2021. DHX is currently taking orders from select alpha+ testers for PEREGRiNE and KESTREL motors. For more information email us at
