The EW-T12000-450 is a high-integration distributed drive in-wheel motor designed for mid-to-high-end electric vehicles, including passenger cars, SUVs, off-road vehicles, and special-purpose vehicles. This fully integrated electric wheel system combines the motor, reducer, brake, and suspension components into a single unit, eliminating the need for traditional drivetrains, axles, and differential gears—resulting in improved space utilization, reduced weight, and enhanced vehicle dynamics.

The motor delivers an impressive peak torque of 12,000N·m, enabling strong acceleration and hill-climbing capability even under heavy loads. With a torque density exceeding 72N·m/kg, it offers one of the highest power-to-weight ratios in the industry, making it ideal for high-performance applications. The maximum speed is 450rpm, which supports efficient operation at low to moderate speeds typical of urban and off-road driving.

The system features a direct-drive design with minimal mechanical losses, achieving efficiency greater than 93% across the operating range. This high efficiency contributes to extended driving range and reduced energy consumption. The compact and robust structure ensures excellent mechanical strength and resistance to shock and impact, making it suitable for use in rough terrain or high-vibration environments.

Engineered for reliability: operates reliably from -40°C to +125°C, withstanding vibrations up to 5g RMS and shock loads of 50G. The IP67-rated housing protects against dust ingress and temporary immersion in water, making it suitable for use in wet, dusty, or muddy conditions typical of urban and rural roads.

The integrated brake system provides regenerative braking and mechanical stopping, improving overall energy recovery and safety. The modular design allows for easy integration into existing vehicle platforms, reducing development time and cost for OEMs. It is specifically designed to fit 20-inch wheel rims, ensuring compatibility with modern vehicle designs.
