Import 2100nm Ac Ev Bus Motor And Planetary Reducer — Buy in wholesale FOB from Supplier in Global Markets

The Rawsun Technology RMHD2100 is a three-phase synchronous motor with integrated planetary reducer designed specifically for electric bus applications. This dual-motor system combines an ISG (Integrated Starter Generator) motor rated at 100kW continuous power with 180kW peak capability, paired with a TM (Traction Motor) delivering 80kW rated and 150kW peak power. The motor assembly achieves a total weight of 296kg and features IP67 protection rating, ensuring complete dust immersion and water resistance suitable for vehicle chassis mounting. The maximum output torque reaches 2100Nm, making this unit suitable for heavy-duty bus propulsion systems requiring high starting and climbing torque.

The RMHD2100 utilizes industrial-grade steel and aluminum alloy construction with precision-machined planetary gear reduction stages. The ISG motor produces 260Nm rated torque with 450Nm peak, while the TM motor delivers 750Nm rated and 1700Nm peak torque. The motor windings are designed for three-phase AC operation with thermal class H insulation, and the housing incorporates integrated cooling channels for sustained high-power output. The CE certification confirms compliance with European electromagnetic compatibility and safety standards for vehicle electric motors. Efficiency rating of 95% is achieved through optimized magnetic circuit design and low-friction bearing systems.

This motor reducer assembly targets electric bus manufacturers, urban transit operators, and EV powertrain integrators requiring validated drivetrain components. The product serves the growing electric public transportation sector where reliability and continuous power delivery are critical. Buyers should verify the specific planetary gear ratio required for their drivetrain configuration, as the listing specifies maximum output torque without detailing reduction ratios. Trade terms typically involve FOB or CIF arrangements with the supplier located in Shantou, Guangdong Province, and buyers should confirm exact packaging dimensions for containerized shipping.

Rawsun Technology (Shantou) Co., Ltd operates from Room No 1, 13th Floor, No. 83, Jinsha Rd., Jinping, Shantou, Guangdong Province, China 515047. The supplier holds a harbor trust tier rating, indicating verified business registration and address confirmation. The listing shows zero response rate and zero average response hours, which reflects current listing data rather than verified supplier responsiveness metrics.

The supplier profile indicates specialization in EV motor systems without specifying manufacturing capacity, employee count, or years in operation. The listing states the product is manufactured in China with CE certification but does not provide additional quality management system certifications such as ISO 9001. Buyers should note that the address corresponds to an office location rather than a visible production facility.
