As a leading company in China's internal combustion engine industry, Weichai Power's engines are used in a wide range of engineering vehicles in China. By 2024, for example, Weichai's gas-fired heavy-duty truck engine market share is projected to reach 60%. The launch of its all-new gas-powered WP16NG4.0 product is leading a new revolution in the industry. The currently released Weichai Power 445 platform permanent magnet synchronous motor technology offers more reliable, efficient, and intelligent features, including multi-functionality, enhanced efficiency, robust protection, and intelligent matching. It also provides a groundbreaking solution for extended-range mining truck powertrains. Below, we will analyze the Weichai Power 445 platform permanent magnet synchronous motor technology.
Currently, mining trucks face three core challenges:
High energy consumption: Traditional diesel powertrains consume up to 80L/100km under heavy-load climbing conditions;
Emission restrictions: Closed mining environments have stringent NOx/PM emissions requirements (must meet the National IV non-road standard);
Range anxiety: Pure electric mining trucks face a bottleneck during continuous operation due to a lack of charging stations.
Weichai Power's 445 platform permanent magnet synchronous motor (peak power 445kW, maximum torque 2800N·m) utilizes an innovative range-extended technology architecture to achieve:
A 38% reduction in overall energy consumption (measured data);
Over 60% reduction in exhaust emissions;
A range exceeding 500km (diesel engine + power battery operating in synergistic mode).
Dual-Mode Cooling System
A hybrid oil and water cooling solution keeps the motor's operating temperature below 85°C.
Overload capacity is 15% higher than the industry average.
Intelligent Energy Management
Adaptive control algorithm based on operating conditions (Patent No. CN2024102*****).
Enables:
Kinetic energy recovery efficiency ≥ 92% on downhill sections;
Optimal power allocation between the diesel engine and the electric motor under heavy loads.
Modular Design
Highly integrated motor controller and drive motor (23% volume reduction);
Supports rapid replacement and repair (MTTR < 2 hours).

The China Construction Machinery Industry Association predicts that by 2026, extended-range mining trucks will account for 45% of the new energy mining truck market. Weichai's technology offers three key benefits:
Laying the foundation for electric drive for hydrogen fuel cell mining trucks;
Promoting zero-carbon mining operations;
Reshaping the TCO (total cost of ownership) calculation model for mining vehicles.
