Import Direct Drive Motor + Motor Controller — Buy in wholesale FOB from Supplier in China

The RDD1000 direct drive motor and controller system from Rawsuns is a complete EV conversion kit designed for medium-duty commercial vehicles, including 4.5 to 8 ton trucks and 6 meter buses. It uses a permanent magnet synchronous motor (PMSM) with a rated power of 90 kW and a peak output of 172 kW, delivering 450 Nm of continuous torque and up to 1000 Nm at peak. The motor operates at a rated speed of 1910 rpm with a maximum speed of 4500 rpm, and is rated IP67 for dust and water resistance, making it suitable for harsh operating environments.

The system is built around a PMSM architecture, which is standard in modern EV propulsion for its high efficiency and torque density. The controller is matched to the motor’s electrical characteristics, ensuring smooth torque delivery and regenerative braking capability. The unit is designed as a drop-in replacement for traditional drivetrains, eliminating the need for gearboxes and reducing mechanical losses. Materials used in the stator and rotor are selected for thermal stability under sustained high-load conditions, typical of commercial vehicle applications.

This kit is purchased by fleet operators, EV retrofit specialists, and bus manufacturers seeking to upgrade diesel-powered fleets to electric. Buyers typically require proof of thermal management performance under continuous duty cycles and validation of the IP67 rating under real-world vibration and moisture exposure. Packaging is industrial-grade, with the motor and controller shipped separately in anti-static, shock-absorbing crates. Trade terms are FOB Shantou, with lead time confirmed upon order placement. MOQ is one unit, but volume discounts are available for orders of five or more.
