EV-builder DeltaWing to use DHX motors with direct-winding heat exchange system



EV-builder DeltaWing Technology Group and motor-maker DHX Electric Machines have announced an agreement granting DeltaWing the rights to make and use DHX motors for automotive applications.
Georgia Tech spinout DHX has relocated to DeltaWing’s campus in Braselton, Georgia, and the companies are ramping up motor production and developing applications for several automotive projects.
DHX’s motors use a proprietary direct cooling technology that’s designed to remove motor heat at the source – the stator windings. The direct-winding heat exchange system features a cooling surface up to 4 times larger than that of a standard cooling channel. According to DHX, its technology removes more than 10 times the heat of a standard coolant channel, which means about 4 times more current and thus 4 times more torque.
“Our DHX Falcon electric motor features standard materials, not exotic steels and magnets,” said DHX CEO J. Rhett Mayor. “It achieves power densities of 120 horsepower per gallon (25 kW per liter) and extraordinary torque of 195 lb-ft/gallon (70 N•m/l). In simple terms, it delivers the power and torque of the standard sedan’s powertrain in the space of a one-gallon can of paint.”
DeltaWing’s most visible vehicle is the DeltaWing road car, a lightweight racer that features a narrow front axle. However, the company plans to apply DHX’s motors to a variety of road-going vehicles, from scooters and small urban vehicles to everyday automobiles and delivery vans.
“This is a marriage of two innovative approaches – one bringing to market the DeltaWing vehicle architecture, and the other an electric motor tech leader able to make amazing power and torque in a tiny package,” said Don Panoz, Chairman of DeltaWing Technology Group. “We’re both entrepreneurial dreamers and together we’ll change cars as we know them today.”
