Rawsuns READ Series e-Axle is a high-performance, modular electric drive system designed to deliver seamless power delivery and adaptability across light-duty logistics, heavy-duty trucks, and specialized agricultural machinery. Combining motor, gearbox, and controller into a single compact unit, it eliminates traditional drivetrain complexity while maximizing efficiency and reliability.
Key Advantages of the READ e-Axle
- Ultra-Compact Integration
• All-in-One Design: Integrates PMSM motor, multi-ratio gearbox, and control electronics into a single housing, reducing space by 40% vs. conventional drivetrains.
• Weight Savings: Ideal for 3.5T-4.5T Sprinter vans and 6m buses where payload capacity is critical.
- Dual-Ratio Flexibility
• Single-speed reduction gearbox
• Multi-speed AMT
3. Robust Performance
• Wide Power Band
• High Torque Density
4. Adaptive Durability
• IP67 Protection: Resists dust, mud, and high-pressure water jets, ensuring reliability in harsh environments (e.g., farming, mining, municipal fleets).
• Thermal Management: Liquid-cooled motor and gearbox sustain peak performance even under 150% overload.
