Racing Game Steering Wheel

Direct-Drive Brushless External Rotor Motor Solution for Force Feedback Steering Wheels

Force feedback steering wheels represent a high-end product in the world of racing simulation games. They deliver an immersive racing experience by realistically replicating real-world driving sensations.

Traditional force feedback systems often utilize a small DC motor combined with a reduction gearbox. While this setup achieves low-speed, high-torque output through gear reduction, it suffers from low transmission efficiency. Additionally, the motor typically operates at high speeds before reduction, and the multi-stage gearing tends to generate significant noise, compromising the user experience.

To address these limitations, Fenghui Motor has developed a specialized brushless DC motor solution for racing game force feedback steering wheels. This system employs a direct-drive brushless external rotor motor that provides high-torque, low-speed output with improved efficiency. The steering wheel is mounted directly onto the motor output shaft, delivering a more immediate and responsive feel.

With this solution, users can sense every tire slip and weight transfer, experience tire traction through corners and varying terrain, and detect understeer or oversteer during drifts. The powerful direct-drive force feedback technology realistically simulates dynamic resistance, enabling precise and timely responses for a truly immersive experience.

Through optimized internal design of the external rotor brushless motor—including a multi-pole magnetic field and structural enhancements—the motor ensures smooth operation at low speeds. Furthermore, unique cooling designs for the stator windings effectively manage temperature rise during continuous high-torque operation, ensuring reliable and sustained performance. Several new structural and technical innovations developed for this project have also been filed for patent protection.

Moving forward, Fenghui will focus on optimizing motor costs to better meet market demands. With nearly two decades of experience in precision motor automation and an extensive database of steering wheel drive prototypes, we offer tailored solutions with compatible controllers, encoders, or custom gear ratios—enabling rapid development of motor systems that meet or exceed customer expectations.
