Cellphone Propulsion Applied sciences has introduced its new Sonic X in-wheel electrical motor platform, designed for high-performance battery-electric and hybrid automobile architectures with restricted onboard house. The Sonic X system provides as much as 300 kW peak (200 kW steady) energy per wheel with a further weight of solely 25 kg (55 lbs), becoming inside commonplace 20 to 23-inch rims. Elaphe says that this strategy reduces powertrain weight by 40% in comparison with a standard dual-motor e-axle system.
The motors function direct-drive, transmission-free motors paired with onboard silicon carbide inverters out there in single or dual-unit packaging. The platform incorporates Elaphe’s high-speed management software program straight inside the inverter to deal with electrical motor operation, wheel slip administration, brake mixing and non-obligatory torque vectoring. For integration in hybrid automobile configurations, the software program can present mechanical differential management.
Elaphe says its high-speed embedded traction management software program can ship 15% improved acceleration and braking efficiency and permits for five% quicker cornering speeds in comparison with conventional designs. The system accommodates massive friction brake discs (350 to 420 mm diameter) and makes use of high-power brake mixing know-how for improved braking efficiency and shorter stopping distances in comparison with friction brakes alone.
The Sonic X platform will help an axle peak energy of as much as 1 MW and a peak axle torque of as much as 9,000 Nm in rear-wheel drive purposes. Its compact type issue—10% the footprint of standard high-performance twin e-axle designs—is focused at purposes the place onboard house is proscribed.
Automotive producers can acquire samples of the Sonic X in-wheel motor system beginning within the first quarter of 2026.
