DHX Electric Machines, Inc. was founded in January 2014 by Dr. J. Rhett Mayor, Ms. Su Mayor, and Dr. Andrew Semidey, to commercialize the patented, proprietary micro-feature enhanced DwHX cooling technology. With GRA funding from Georgia Tech VentureLab, the technology was successfully demonstrated in June 2014. 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 Georgia Tech Research Corporation.


DHX started operations in August 2014 on the Georgia Tech campus in an incubation space. DHX started earning revenue in October 2014 with a multi-national corporation elevator company contract. The company transistioned 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, with the assistance of its angel investor, the late Dr. Don Panoz in 2015.


DHX started selling Hawk 20, 40, and 60 motors in 2016. Our Hawk motors have been deployed in military and amphibious vehicles, electric motorcycles, agriculture platforms, electric race cars, boats, yachts, academic labs, eATVs, and utility vehicles. Since 2014, DHX has earned $2 million+ in revenue in the form of product development revenue, product sales, licensing activities, and engineering services.


DHX integrates efficiently with R&D and Product Development teams to provide specialized electric machines design solutions for niche markets.  DHX uses industry-standard electromagnetic design FEA tools and CAE design and CAM software for rapid development cycles, enabling custom, application-tailored motors for our customers. We have developed motor solutions for a multitude of applications, including vertical traction, HVACR compressors, marine applications, e-ATVs, golf carts, aerospace, and in portable power generation systems.


DHX will consider technology transfer and licensing for large volume applications, allowing us to continue doing what we do best Innovate Technologies + Transform industries.
