This New EV Motor KILLS the Old Design
A Munich startup called Deep Drive is turning heads with a dual-rotor, yokeless electric motor that promises huge torque, higher real-world efficiency, and lower material use. I met their team at a conference and dug into the engineering, from how dual rotors boost active surface area to why removing the yoke changes everything. The real secret is their torsion-resistant, truss-like copper bar windings that solve both stiffness and cooling. We’ll break down the design, the numbers, and why automakers are paying attention, including BMW.
