New Cooling Technology Leads to Units 75% Smaller, Lighter Too

Georgia’s DeltaWing Technology Group is trumpeting a marriage of technologies for smaller and lighter motors for electric vehicles. DeltaWing has secured rights from DHX Electric Machines and “to make, use and sell ground-breaking electric motors and components specifically designed for automotive applications.”

The DeltaWing Technology Group and DHX Electric Machines have come up with an electric motor design boasting ‘amazing power and torque in a truly tiny package.’ The 80-horsepower DHX Falcon electric motor is shown in the forground with a conventional 1.5-horsepower electric motor behind.

The firms’ motors are 75% smaller than conventional motors, DeltaWing says, and are significantly lighter. The key is new technology for handling heat, “which is the enemy of a motor’s efficiency.”

“This is a marriage of two extremely innovative approaches – one bringing to market the state-of-the-art and efficient DeltaWing vehicle architecture and other vehicle platforms, and the other an electric motor tech leader able to make amazing power and torque in a truly tiny package,” DeltaWing Technology Group chairman Don Panoz said in a release.

‘Disruptive Cumulative Technologies’

“We’re both entrepreneurial dreamers and together we’ll change cars as we know them today. That’s why we’re coining our approach disruptive cumulative technologies.”

“Rather than developing a new motor and placing it in conventional vehicle platforms, DeltaWing and DHX are combining their respective technologies to reach new levels of EV transportation energy efficiency and range,” states the release.

‘New Cooling Technology’

Also according to today’s announcement, “The majority of the thermal losses in high-torque electric motors are generated in the windings. Heat typically dissipates through the stator to the frame via air or liquid cooling.

DeltaWing hopes to use the powerful new DHX motors in a new generation of electric vehicles.

“DHX Electric Machines’ patented advanced cooling uses the Direct-Winding Heat Exchanger (DWHX) to remove the heat right at the source. Each DWHX features tiny channels to dissipate heat, significantly reducing thermal resistance and increasing efficiency.”

“Our DHX Falcon electric motor features standard materials, not exotic steels and magnets,” said DHX president and co-founder Rhett Mayor. “It achieves power densities of 120 horsepower per gallon (25 kilowatts per liter) and extraordinary torque of 195 ft-lbs/gallon (70 Nm/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.”

‘Game-Changer’

“Imagine a light and cool-to-the-touch 20-horsepower motor the size of a 12-oz. can, and one that fits in two hands and puts out 80 or more horsepower,” said Panoz. “It’s simply a transportation game-changer. We’ll use it in our DeltaWing road car architecture, which studies show is already in the range of the 2025 CAFE requirements.”

The announcement notes that DHX Electric Machines Inc. has relocated to the DeltaWing Technology Group campus in Braselton, Ga. Both firms “are ramping up electric motor production and developing applications for multiple DeltaWing Technology Group automotive projects.” Potential applications range from scooters and small vehicles for congested urban areas to everyday automobiles and delivery vehicles.
