The demand for high-speed long-travel seat rails in automotive applications stems from new energy vehicles' pursuit of ultimate space flexibility and safety. These rails must enable rapid, smooth, and wide-range electric adjustment of second- and third-row seats to flexibly switch between passenger and cargo modes. In the event of a collision, they must retract swiftly in coordination with the collision warning system to create survival space.

To address these requirements, HengDrive provides high-power-density, low-noise brushless DC servo motors and automotive-grade synchronous controller ECUs. This solution delivers high torque output, rapid response, and smooth operation, enabling precise control of high-speed, long-distance, low-vibration rail movement. It meets automotive-grade safety and durability standards, providing core power assurance for intelligent seat systems.
