DHX ELECTRIC MACHINES, INC. is an independent, closely-held startup company producing state-of-the-art, ultra-high torque density electric machines, incorporating the patented, proprietary micro-feature enhanced "Direct-Winding Heat Exchange" DWHX™ cooling system developed in MayorLab at the George W. Woodruff School of Mechanical Engineering at Georgia Tech. The DWHX™ cooling system targets the cooling effect directly at the heat source, the stator windings, and with the micro-feature enhancement, effects are capable of removing up to 16 times the heat of conventional cooling systems. Consequently, the DHX® cooling system provides a 4 times increase in torque per volume that allows DHX electric motors to produce the same torque in 75% of the space of the conventional motor. DHX has industry-standard electromagnetic design FEA tools and custom multi-disciplinary design codes for rapid production development cycles, empowering DHX to develop custom, application-tailored motors to its customers.


Founded in 2014, DHX Electric Machines, Inc. was formed after the successful demonstration of the DWHX™ cooled 15kW ultra-high torque density electric motor, funded by the Georgia Research Alliance via Georgia Tech's VentureLab, which validated 10 years of research in the areas of micromanufacturing, liquid cooling technologies, portable power generation and electro-mechanical design at MayorLab. DHX  relocated in 2015 from the Georgia Tech campus to Braselton, GA, moving into a 20,000 sq.ft production facility equipped with lean manufacturing cells, CNC machining centers, and coil production of motors sized up to 300kW. The company is in the early growth stage with motor offerings in vertical traction, HVAC compressor, marine applications, and golf cart markets. DHX is also engaged in advance R&D initiatives for military applications. DHX looks forward to entering areas of wind generation applications soon.



The DHX ELECTRIC MOTOR opens technological advancement possibilities. We develop and test our motors in-house. We also team with key strategic partners to license the DwHX cooling technology for niche applications. With current product offerings at four power levels, DHX is preparing to expand its manufacturing capability to increase volume production.
DHX MOTOR APPLICATIONS, the golf cart as a transportation solution. DHX is having A. LOT. OF. FUN. installing our motor technology in electric golf cart platforms. We feel strongly that our motors serve a greater purpose than simply giving a driver more POWER. With our units having a smaller material footprint, we believe that sustainability, clean energy, and lower costs are key considerations to achieve reliable and efficient global transportation solutions. Large scale, interconnected life style driven developments such as residential communities, academic and commercial campuses are already shifting to clean, safe, low-speed people-moving-options.
