Overview
Key Differentiators
- Highest torque-per-kg of any production automotive electric motor at time of launch
- Axial-flux topology cuts axial length by ~60% vs equivalent radial-flux designs
- Segmented stator eliminates traditional winding interconnects, reducing fault propagation risk
- Oil-cooled stator enables continuous high-power without derating in track conditions
- Modular architecture supports single, dual and quad-motor configurations on one platform
Materials & Procurement Intelligence
Key materials used in this component, with supply chain risk and sourcing notes.
Neodymium-Iron-Boron (NdFeB) Magnets
High RiskRotor permanent magnets — highest energy density available commercially
Procurement note: Critical rare-earth dependency; >85% of global supply from China. Recommend dual-source strategy and futures hedging.
Electrical Steel (Silicon Steel)
Medium RiskSegmented stator laminations — minimises eddy-current losses at high frequency
Procurement note: Specialist grain-oriented grades required (e.g. JFE Super Core). Lead times 8–16 weeks from tier-1 steel mills.
Copper Windings
Low RiskSegmented stator coil windings — precision-wound flat-pack conductor segments
Procurement note: LME copper pricing; relatively stable but custom profile winding requires qualified winding suppliers.
Carbon Fibre Composite
Medium RiskRotor disc and housing components — structural weight reduction
Procurement note: Aerospace-grade prepreg. Toray T700/T800 typically specified. Autoclave cure required.
Aluminium Alloy
Low RiskMotor housing, end plates and mounting brackets
Procurement note: A380 / A6061-T6 die-cast and machined. Readily available, low supply risk.
