The WSM-T1600-530 is a highly integrated wheel-end drive system designed for medium-duty electric commercial vehicles such as urban buses, delivery trucks, and logistics vans. It integrates the permanent magnet synchronous motor (PMSM), planetary gear reducer, and power electronics into a single, compact module—enabling distributed drive architecture where each axle or wheel is independently powered. This design offers superior traction control, improved energy efficiency, and enhanced maneuverability compared to centralized drivetrains.
At its core lies a high-efficiency PMSM delivering 1600N·m peak torque and 530Rpm peak speed, paired with a precision planetary gearbox to optimize power transmission. The system achieves >45N·m/kg torque density, making it ideal for applications requiring high performance in limited space. The integrated power electronics use SiC MOSFETs for fast switching and low losses, achieving >92% overall efficiency across the operating range.
Regenerative braking is fully supported: during deceleration, the motor acts as a generator, converting kinetic energy back into electrical energy to extend driving range. The IP67-rated housing ensures complete protection against dust ingress and temporary immersion in water, while the high mechanical strength design withstands impacts from urban roads and heavy loads. The unit features built-in thermal management with heat sinks and cooling channels to maintain stable performance under prolonged operation.
Engineered for harsh environments: operates reliably from -40°C to +125°C, withstanding vibrations up to 5g RMS and shock loads of 50G. Manufactured under IATF 16949 with ISO 26262 ASIL-B functional safety compliance. All units undergo 1,000-hour accelerated life testing, thermal cycling validation, and full-load endurance tests. Supports white-label customization with rapid NPI cycles (14 days) and regional compliance packages (EU Type Approval, China CCC, U.S. DOT).
