Society of Automotive Engineers (SAE) World Congress Detroit 2011.. Shades of Preston Tucker’s Torpedo: “Protean Electric Tackles The Unsprung-mass ‘Myth’ of In-wheel Motors”

Exploded view of Protean’s PD18, a liquid-cooled, three-phase, permanent-magnet motor integrated into the corner assembly. Each motor features distributed architecture, incorporating one inverter and eight power-electronics modules within the motor. It is rated at 84 kW peak power for 20 s and 54 kW continuous, depending on battery power, and is scaled for vehicle curb weights of 5000-6000 lb.
