Delivering a New Class of Lightweight Electric Vehicles

Feb. 14, 2022

Indigo Technologies uses a unique wheel-motor system to build an efficient, stable electric car.

Check out our CES 2022 coverage.

Indigo Technologies was highlighting its new Flow Plus, which is part of the company's Flow family of lightweight electric vehicles, at this year's CES. I spoke (video above) with CEO Will Graylin about the announcement as well as the underlying technology.

Indigo Technologies offers both its wheel-motor technology as well as finished vehicles. Targeting ride-sharing and delivery, the lightweight vehicles will have a 250-mile range using a 40-kWh battery. The wheel motors not only provide an efficient ride, but a very smooth one as well because of its split stator design.

This video gives a glimpse into the features and operations of their hub motors:

The wheel has some impressive specs:

Direct drive, dual stator electric motor
- 22-kW peak power
- 250-Nm peak torque x 3 or 4 corners
Inverter and power electronics
- 350-V bus voltage
Fully active high-bandwidth suspension
90% efficient regenerative braking and suspension
Integrated mechanical safety brake
Adaptive, simultaneous control of horizontal propulsion and vertical suspension
Torque vectoring plus yaw and roll control
Mounts to standard wheels and 18-inch tire sizes
Steerable MacPherson strut or double wishbone configurations

I earned a Bachelor of Electrical Engineering at the Georgia Institute of Technology and a Masters in Computer Science from Rutgers University. I still do a bit of programming using everything from C and C++ to Rust and Ada/SPARK. I do a bit of PHP programming for Drupal websites. I have posted a few Drupal modules.

I still get a hand on software and electronic hardware. Some of this can be found on our Kit Close-Up video series. You can also see me on many of our TechXchange Talk videos. I am interested in a range of projects from robotics to artificial intelligence.
