Import Boat Motor — Buy in wholesale FOB from Supplier in China

Rawsuns manufactures a permanent magnet synchronous motor (PMSM) designated RDD730, engineered for marine electric propulsion with applications extending to 3.5 tonne light truck platforms. The unit operates at a battery rated voltage of 540 VDC and delivers a continuous output of 60 kW with a peak of 100 kW. Rated torque is 300 Nm, climbing to 730 Nm at peak, which suggests substantial low-speed pulling power relevant to vessel displacement hulls. The motor carries an IP67 ingress protection rating and a 50 Hz operational frequency, with three-phase architecture and waterproof construction as standard.

The PMSM topology offers higher efficiency and power density than induction alternatives, particularly valuable in marine environments where battery capacity and thermal management constrain range. The 540 VDC nominal bus aligns with contemporary high-voltage EV architectures, reducing copper mass in cabling compared to 400 V systems. IE1 efficiency classification is stated, which is the baseline tier under IEC 60034-30-1; buyers should clarify whether higher efficiency variants (IE2 or IE3) are available for regulatory compliance or extended range. The 100 kg mass is relatively compact for the torque output, though the complete drivetrain mass including controller, cooling, and reduction gearbox must be factored into vessel stability calculations.

This motor suits commercial ferry operators, government patrol craft, and private yacht owners converting from combustion to electric propulsion. The 3.5 tonne truck reference indicates the platform shares architecture with automotive applications, which may accelerate parts availability but requires confirmation of marine-specific validation such as vibration testing per IEC 60068-2-6 and salt mist exposure per IEC 60068-2-52. Warranty coverage is stated at 12 months. Buyers should confirm with Rawsuns whether this warranty applies globally, what components are covered, and whether extended marine warranties are offered.

Rawsuns operates from a facility at Room 1, 13th Floor, No. 83 Jinsha Road, Jinping District, Shantou, Guangdong Province, China. The company is classified at harbor trust tier within this marketplace, with a response rate of 0.00 percent and no recorded average response hours. The address format indicates a commercial office rather than manufacturing plant, suggesting Rawsuns may operate through a design and assembly model with production contracted to dedicated facilities.

The listing provides specific technical data for the RDD730 EV kit, including voltage, power, and torque figures, but omits company history, factory certifications, R&D headcount, annual production capacity, and export market experience. The dual application reference, boat and 3.5 tonne light truck, indicates a platform strategy rather than marine-specialised engineering. Buyers should request: ISO 9001 or IATF 16949 quality certification, marine type approval from bodies such as Bureau Veritas, DNV, or RINA, and evidence of salt mist and vibration testing to IEC marine standards. Direct communication with Rawsuns engineering staff is advisable to confirm whether the 12-month warranty covers marine duty cycles and saltwater exposure.
