Maserati GranTurismo Folgore is the latest model to feature the innovative technology of Italian automotive supplier Marelli. The company developed and manufactured three e-motors for the car, which are installed on the front and rear axles and provide a total power of 1,200 hp in a compact profile. The motors boast a power density of 9.2 kW/kg and a total torque of 1,350 Nm.
Marelli’s proprietary Adaptive Driving Beam Matrix LED headlamps and Telematic Control Unit connectivity system are also featured in the car. The motors are made with solid conductors in the hairpin windings of the stator, which improves electromagnetic and thermal performance and increases the filling factor to more than 80%. The rotor geometry and segmented magnets, as well as optimized skew of the laminate stack, reduce noise, vibration and magnetic cogging. The cryogenic cooling process used in rotor production, reaching about -200° C, ensures perfect fit of the shaft into the stack.
The motors were developed over a two-year span and produced at Marelli’s Modugno plant in Bari, Italy. With its cutting-edge technology, Marelli has enabled Maserati to create a car that is both powerful and efficient.
