Rawsuns PHD Series EV motor – Cost-Efficient Hybrid Drive System with AMT for Versatile Commercial Vehicles
The Rawsuns PHD Series combines a single PMSM motor with an automated manual transmission (AMT) in a coaxial motor-engine layout, featuring an automatic clutch for seamless transitions between pure electric, hybrid, and conventional propulsion modes. Designed for fleets prioritizing affordability and adaptability, it excels in urban, suburban, and highway routes with demanding gradients.
Core Advantages
- Tri-Mode Flexibility
• Pure Electric Mode: Zero-emission operation for urban zones (e.g., last-mile delivery).
• Hybrid Mode: Engine-motor synergy cuts fuel consumption by 50%+ on mixed routes.
• Conventional Mode: Diesel-only power for remote areas with limited charging.
- Robust Performance
• 29,000 Nm Max Output Torque: Tackles 40%+ gradients, ideal for mining access roads or mountain highways.
• Wide Gear Ratio Range: Keeps engines in low-RPM high-efficiency zones across all terrains.
• Overdrive Gear: Reduces energy loss at cruising speeds (e.g., 8.5m intercity coaches).
- Unmatched Reliability
• Limp-Home Capability: AMT operates even with motor/controller failure, ensuring mission continuity.
• High-Voltage Fault Tolerance: Vehicle remains drivable during electrical system faults.
4.Cost Efficiency
• 30% Lower TCO: Simplified AMT design cuts maintenance costs vs. dual-motor systems.
• Plug-and-Play Retrofit: Compatible with existing diesel chassis (e.g., Freightliner, MAN).
Technical Specifications
• Max Torque: 29,000 Nm
• Max Gradeability: ≥40%
• Transmission: AMT with precision-ground gears, reverse gear, and overdrive
• Clutch: Automatic dry clutch (200,000+ cycles)
• Efficiency: 50%+ fuel savings in hybrid mode
Recommended Applications
• Urban/Suburban Routes: Stop-and-go traffic for 6-12m buses or 4.5-7t delivery trucks.
• Steep Gradients: Port access roads, mining slopes, mountain highways.
• Long-Haul Logistics: 6×4 tractors on 500+ km routes with sparse service points.
RPHD Series Enhanced Benefits
• Adaptive Gearbox: Fully ground gears enhance shift smoothness and durability.
• Extended Electric Range: Optional larger batteries for 100+ km pure EV operation.
• Thermal Resilience: Liquid-cooled motor sustains peak torque in desert/arctic conditions.
