Ferrari Engine light

The power train of the Ferrari Luce consists of four electric motors, one per wheel. These are permanent-magnet synchronous motors with radial flux, derived from the experience of the F80 and powered by the know-how Ferrari gained in Formula 1 and the World Endurance Championship. The system operates at a maximum of 800 volts. The data sheet indicates a maximum power output of 772 kW, equivalent to 1050 horsepower, and a maximum torque at the engines of 990 Nm. Maximum torque at the wheels is 11150 Nm. The front axle develops 210 kW, while the rear axle reaches 620 kW. The front engines reach a maximum speed of 30000 rpm, the rear engines 25500 rpm. The power density of the axle reaches a total of 4.80 kW per kilogram. The configuration with two motors per axle was not only chosen to increase power. The main function is torque control. On each axle, torque can be managed independently between the left and right wheels, both under acceleration and braking. This allows full torque vectoring, with advantages in terms of precision, stability and natural response. At the rear, in Launch Control mode, up to 7750 Nm are transferred to the axle after reduction. It is important to distinguish between engine torque, system torque and torque at the wheels, because in the electric world, torque values can be misleading if not put into context. On a technical level, the stators adopt concentrated pole windings to reduce overall dimensions, 0.2 millimetre laminations to improve consumption at high speeds, Formula 1-derived Litz wire and vacuum resin coating with high thermal conductivity resin. The rotor uses surface mount magnets with Halbach configuration, which concentrates the magnetic flux towards the stator, and carbon fibre sleeves to resist centrifugal forces at higher speeds. The result is a 0-100 kilometres per hour in 2.5 seconds, 0-200 in 6.8 seconds and 310 kilometres per hour top speed, but the most specific part of the design remains the ability to control each wheel very precisely. This is where the electric is used as a dynamic element, not just as a source of power.
