Rawsuns RSTM Series EV Motor – Multi-Role Power Solution
The Rawsuns RSTM Series are IP67-rated liquid cooling permanent magnet synchronous motors (PMSM) engineered for direct-drive propulsion and onboard power generation (25-100 kW rated / 50-200 kW peak power, 80-1,000 Nm rated / 180-2,500 Nm peak torque; 955-3000rpm rated/ 2700-6000rpm peak speed), delivering unmatched versatility across commercial vehicles, marine systems, and extreme-duty applications.
Key Advantages of RSTM Series Motors
- Dual-Function Design:
• Acts as a propulsion motor for vehicles/vessels or a high-efficiency generator for hybrid/range-extended systems.
• Eliminates gearbox dependencies, reducing energy loss by 15% vs. traditional systems.
- Compact & Lightweight:
• Space-saving direct-drive structure ideal for constrained installations (e.g., light trucks, urban buses).
- High Energy Efficiency:
• 96%+ efficiency across all load ranges, optimized for stop-and-go urban logistics or long-haul routes. - Adaptive Power Modes:
• Seamlessly switch between motor mode (propulsion) and generator mode (energy recovery/backup power).
5.Robust Durability:
• IP67 protection for harsh environments (mining, coastal marine use).
Applications in Vehicles
- Light/Medium Logistics Trucks
• 2-5tons Trucks (Sprinter models, 4.5/5 tons delivery vans): - Direct-Drive Buses & Passenger Vehicles
• 6-10 meter Buses (8 meter city buses, 10 meter intercity coaches):
• 7 meter Direct-Drive Passenger Cars/7.5 tons Trucks:
- Heavy-Duty & Special Vehicles
• 7.5-12 tons Trucks:
Marine Applications
• Hybrid/All-Electric Vessels:
• Propel small ferries or serve as auxiliary generators for hybrid boats.
• Corrosion-resistant design for saltwater environments.
