Import 140kw 3000rpm Ev Motor For Truck Bus Boat — Buy in Bulk from Supplier in Global Markets

The Rawsuns RSTM430 is a three-phase synchronous electric motor designed for heavy electric vehicle applications such as trucks, buses, and boats. It delivers a peak power output of 140 kW at 3000 rpm and a peak torque of 1700 N·m, with a rated power of 92 kW at 1150 rpm. The motor operates on a 540 VDC battery system and achieves a listed efficiency of 96.3%, with an IP67 protection rating for harsh environments.

This unit is built for direct drivetrain integration, featuring a Y-connection winding and a continuous AC voltage of 387 VAC. Its synchronous motor type and three-phase configuration are standard for high-torque EV applications, offering smooth power delivery. The peak current draw is 350 A, which is a critical specification for sizing the vehicle's battery pack and high-voltage cabling. The 115 Hz operating frequency aligns with typical inverter-driven motor control for this power class.

Buyers sourcing this motor are typically EV conversion specialists, commercial vehicle manufacturers, or marine propulsion integrators requiring a robust mid-range power unit. The motor's specifications suggest suitability for applications where sustained torque at moderate speeds is more important than extreme top-end RPM. As with all high-voltage EV components, buyers should verify exact mounting dimensions, shaft specifications, and cooling requirements directly with Rawsun Technology before finalising procurement.
