“While the torque figure could at first glance appear fantastic, standard automotive industry practice only quotes torque at the flywheel not at the wheels,” Evans Electric notes. “As an example the Tesla Model S
Performance has a quoted peak motor torque of 600 Nm. With a single speed reduction gear ratio of 9.73:1 that equates to a total of 5,838 Nm (minus gearing losses) at the wheels. The Evans Electric motors are direct drive, so the rotor turns at the same speed as the wheel. Instead of mechanical reduction gearing, they are electrically geared using an 8 pole stator winding configuration.”
To help you understand the significance of that: direct drive equipment has the benefit of mechanical simplicity, and sometimes efficiency, as the alternatives, which are gear-driven systems, waste energy.
Mechanical equipment cannot get any simpler than direct drive. This is because the motor directly turns the wheels itself. In the case of this Lancer Evo 3 vehicle, it has an electric motor integrated into each of the four 19″ (48 cm) wheels. No gears, no transmission, nothing at all.
