Import Ac Motor Rstm261-J Electric Vehicle Ev Motor — Buy in wholesale FOB from Supplier in Global Markets

The RSTM261-J is a three-phase synchronous motor manufactured by Rawsun Technology (Shantou) Co., Ltd in Guangdong Province for electric vehicle traction applications. This specific model carries a rated power of 34 kW at 3000 r/min, with a rated torque of 110 N.m and rated current of 127 A at the stated operating point. The electrical system operates at 380 VDC with a rated frequency of 200 Hz, indicating a four-pole design running at the given synchronous speed. Peak performance reaches 68 kW and 270 N.m torque, with a maximum speed of 6000 r/min and peak current capability of 320 A, providing substantial overload margin for vehicle launch and gradeability demands.

The motor's peak-to-continuous power ratio of 2:1 is characteristic of automotive traction designs where brief bursts of high output are required for acceleration, while continuous operation must be thermally sustainable. The 380 VDC nominal voltage aligns with common passenger electric vehicle battery pack architectures, though actual operating voltage varies with state of charge. Waterproof protection is specified, essential for underbody mounting exposure, though the precise IP rating should be confirmed. Three-phase synchronous operation with 200 Hz excitation at base speed implies rotor construction either with permanent magnets or separately excited windings, the choice of which affects efficiency, power density and controller complexity. The 12-month warranty period is stated, which is shorter than some competing offerings in this segment.

Typical integration scenarios include pure battery electric passenger vehicles, light commercial vans, and hybrid powertrain applications where the motor serves as the primary or supplementary traction source. The 110 N.m rated torque suits vehicle masses in the 1,200-1,800 kg range depending on final drive ratio and wheel diameter. Buyers must verify controller compatibility, particularly current control bandwidth and field-weakening algorithm suitability for 6000 r/min operation. The supplier's Shantou location in eastern Guangdong provides access to Shenzhen's electronics ecosystem for controller sourcing, though the motor itself ships from the manufacturing site. Platform engineering teams should request the CAD envelope, cooling interface details and NVH test data before committing to vehicle packaging.

Rawsun Technology (Shantou) Co., Ltd operates from Room 1 on the 13th floor at 83 Jinsha Road, Jinping District, Shantou, Guangdong Province, postal code 515047. The company holds a harbor trust tier classification, representing entry-level verification on the platform. The response rate is recorded at 0.00 percent with zero average response hours, indicating no historical response to buyer inquiries is documented. This absence of engagement metrics necessitates proactive follow-up by prospective buyers and potential use of alternative contact methods beyond the platform messaging system.

The supplier's profile indicates specialisation in electric vehicle traction motors, with this listing providing detailed electrical specifications for the RSTM261-J model. No factory size, production capacity, employee count, or year of establishment is disclosed. The listing cites CCC and CE certifications, though buyers should independently verify the certificate numbers, scope and validity dates with the issuing bodies. There is no mention of IATF 16949 automotive quality system certification, ISO 14001 environmental management, or specific OEM customer references. The Shantou location is outside the primary EV manufacturing clusters of Shenzhen and Shanghai, which may influence logistics costs and supplier ecosystem proximity.
