Additional Highlights

• Self-produced Gears: Our built-in gear differential is made from automotive gearbox material, ensuring smooth steering.
• Electromagnetic Intelligent Brake System: The electromagnetic braking system provides fast, effective stopping power. It can brake when the controller is released or when the power is off, offering superior safety compared to electronic brakes.

The ND520 Series, with its numerous advantages, makes a compelling case for your next electric vehicle power solution.

The ND520 Series features an electromagnetic braking system, a cutting-edge technology in the current market. However, it is crucial to distinguish between electromagnetic and electronic brakes.

An electromagnetic brake operates with a solenoid valve, a feature absent in electronic brakes. This system ensures the vehicle can brake swiftly and hold its position even without power. On the other hand, electronic brakes may not provide the same level of firmness, especially when parked on a slope, leading to potential vehicle slippage.

The ND520 Series in Detail

The ND520 Series is a versatile range offering three different power variants – 3000W, 4000W, 5000Wand 7500W. Despite the variation in power, all models share common features such as a high motor efficiency of 92%, and exceptionally low noise levels of ≤60dB.

Furthermore, each model boasts a unique gear ratio, ensuring the perfect balance between speed and torque for your specific application. From the ND520 disc brake 3000’s 1:12.79 gear ratio, perfect for general applications, to the ND520 disc brake  5000’s 1:16 ratio, providing high torque for demanding tasks, there is a model for every need.
