High Overload Capacity

Electric vehicle drive motors must handle 4-5 times their normal load capacity. This capability is crucial for frequent extreme acceleration and climbing steep inclines without stalling.

Wide Speed Adjustment Range

The motor’s top speed needs to be 4-5 times the cruising speed on highways. This ensures the motor can deliver consistent high torque at low speeds and constant power at high speeds, enhancing overall performance.

High Power Density

To maximize efficiency, the motor design focuses on increasing power while reducing weight. The goal is to achieve a power density of at least 1 kilowatt per kilogram, making the motor both powerful and lightweight.

Precision and Controllability

The motor must provide precise control over torque and speed across a wide range. This precision directly affects the driving experience, ensuring smooth and responsive performance under various conditions.

Enhanced Reliability

Electric vehicle motors operate under high temperatures, humidity, and power conditions. Therefore, they require superior waterproofing and reliable performance to withstand these challenging environments.


The Xiaomi SU7 motor excels by meeting these five critical design requirements: high overload capacity, wide speed adjustment range, high power density, precise controllability, and enhanced reliability. These features make it a standout choice in the electric vehicle market, offering superior performance and durability.
