Import 50kw 6000rpm Ev Motor For Truck Bus Boat — Buy in Bulk from Supplier in Global Markets

The RSTM260-J from Rawsun Technology (Shantou) Co., Ltd is a three-phase permanent magnet synchronous motor designed for electric vehicle and marine propulsion applications, with a rated power of 25kW and peak power of 50kW at a maximum rotational speed of 6000rpm. The motor operates from a 380V DC battery bus with an AC voltage of 235VAC, using a Y-connected winding configuration and achieving a tested efficiency of 94.53%. With IP67 ingress protection, the unit is sealed against dust and temporary immersion, making it suitable for under-hood truck installations, bus chassis integration, or marine engine rooms where spray and humidity are present.

The motor delivers a rated torque of 80 N.m with a peak torque capability of 180 N.m, providing the high starting torque required for heavy vehicle launch and hill-climbing without a multi-speed transmission. The 200Hz electrical frequency at rated conditions indicates a four-pole or six-pole permanent magnet rotor design with surface-mounted or interior magnet architecture, though the exact magnet material grade (typically NdFeB N38SH or similar for 150°C capability) should be confirmed with the supplier. Standard industry practice for EV traction motors in this power class includes liquid cooling via an internal water jacket or oil cooling, with continuous power typically 30-40% lower than peak; verify the derating curve and thermal time constant for your specific duty cycle and ambient temperature.

Target applications include 4.5-ton to 8-ton electric truck retrofits, city bus drivetrains, and planing or displacement hull electric boats where the 50kW peak supports temporary acceleration demands while the 25kW rated output covers cruising operation. The 82A rated current and 190A peak current require cable sizing and contactor selection with appropriate thermal margins, and the controller must support field-weakening control above base speed to reach the 6000rpm limit. Buyers should confirm whether the motor ships with or without the inverter/controller unit, what CAN protocol is used for torque demand and diagnostics, and whether the CE marking on the motor extends to the complete drive system or applies to the motor alone. Rawsun Technology (Shantou) Co., Ltd is based in Shantou, Guangdong Province, with harbour trust tier platform status; direct technical enquiry is recommended given the zero platform response rate.

Rawsun Technology (Shantou) Co., Ltd operates from Room 1, 13th Floor, No. 83 Jinsha Road, Jinping District, Shantou, 515047, Guangdong Province, China. The company holds a harbour trust tier on the platform, with a response rate of 0.00% and zero recorded average response hours, indicating that buyers should initiate contact through direct channels to assess technical support responsiveness. No information on year of establishment, factory ownership, R&D headcount, or production volume is available on the current listing.

The company positions itself as a designer of high-efficiency EV motors for electric trucks, buses, and boats, with the RSTM260-J representing a mid-power segment in a broader range spanning 50kW to 200kW peak and 180 N.m to 2800 N.m peak torque. The listing does not state whether Rawsun manufactures the motor in-house or assembles from sourced components, nor does it disclose specific OEM customers, fleet deployment records, or after-sales service network coverage. Buyers should request proof of production capability, quality system certification (ISO 9001, IATF 16949), and reference projects with comparable vehicle integration before committing to volume orders. The presence of CE marking on the motor should be verified against the specific directive and notified body involved.
