250 kW / 500 kW Electric Truck Motor for Heavy Electric Trucks

This 250 kW / 500 kW electric truck motor is specifically designed for heavy-duty electric trucks and municipal vehicles. Compared to the traditional motor and gearbox configuration, this direct-drive motor delivers a maximum output power of 500 kW. For an 8-ton truck, it enables a maximum climbing gradient of 30% (16°) at a speed of 30 km/h, while maintaining continuous climbing performance on slopes up to 12.5% (7°). This technology ensures that heavy-duty trucks exhibit exceptional power and performance, even when navigating steep inclines, making it an ideal choice for demanding applications in challenging environments.

Our Electric Truck Motor Technology

Utilizing high magnetic permeability materials, sinusoidal gap magnetic flux optimization, and segmented rotor slanted pole technologies to enhance the motor efficiency.
The motor achieves a maximum efficiency of over 97%, with the system efficiency exceeding 85% in 90% of the operational range. The motor's no-load noise level is kept below 75 dB(A).
The dual-spiral water channel design enhances the motor's cooling capacity and stability, meeting water resistance and pressure differential requirements.
The junction box employs a stamped sheet metal and vulcanized rubber process, improving production efficiency and reducing material costs.
