Dual-Drive Electric Vehicle Hub Motor

This Dual-Drive Electric Vehicle Hub Motor is especially developed for dual-drive four-wheel low-speed electric vehicles, heavy-duty mobility vehicles for the elderly, sightseeing vehicles, factory patrol vehicles, and mountain commuting vehicles, offered by professional manufacturer Qianjiang Motor. Unlike ordinary single-drive motors, this system uses independent dual-motor drive on the left and right wheels combined with intelligent torque distribution technology.

It effectively solves problems such as weak single-drive power, wheel slipping, poor hill-climbing ability, and deviation under heavy loads. It is an ideal upgraded motor system for heavy loads, mountainous areas, and muddy road conditions.

Core Product Advantages

1. Dual-drive coordinated power

The system uses independent dual-motor drive for the left and right rear wheels, with synchronized power output and evenly distributed loads, eliminating the problem of a single motor operating under excessive load. Under the same total power, the traction of the dual-drive system is much greater than that of a single-drive motor.

Even with multiple passengers or heavy cargo, the vehicle maintains strong power. It can handle 30° steep slopes and continuous inclines with ease, providing strong starting power and smooth acceleration, making it ideal for mountainous and rural roads with frequent slopes.

2. Intelligent electronic differential

Equipped with a four-wheel dedicated electronic differential algorithm, the system automatically adjusts the speed and torque of the left and right motors according to the steering angle and vehicle speed. During straight driving, both motors provide synchronized power for smooth and stable operation.

When turning, the system intelligently adjusts the speed difference between the inner and outer wheels, effectively solving problems such as jerky turning, dragging, tire wear, and deviation commonly found in ordinary dual-drive vehicles. It provides precise steering, smooth cornering, and significantly improved driving experience.

3. Strong anti-slip performance and excellent capability on complex terrain

On uneven terrain, muddy roads, wet or snowy roads, and gravel surfaces, the dual-drive system intelligently distributes power to prevent individual wheels from slipping or spinning freely.

Both wheels provide balanced traction, greatly improving the vehicle's ability to overcome obstacles and maintain stability. It is suitable for daily commuting, outdoor operations, and complex rural road conditions.

4. High-density copper windings + NdFeB magnets

Both motors use high-purity copper precision windings combined with thick, high-flux NdFeB magnets. The optimized magnetic circuit provides strong magnetic force and responsive power output.

The dual motors provide sufficient torque reserves, reducing the risk of overheating and demagnetization during long periods of heavy-load operation, while maintaining stable power output. Compared with ordinary single-drive motors, durability and performance stability under demanding conditions are significantly improved.

5. Fully sealed waterproof and dustproof design

Both motor housings are made of thick die-cast aluminum alloy, providing excellent resistance to pressure and impact without easy deformation. Combined with multi-layer sealing rings and an integrated waterproof cable-entry design, the motors achieve an IP54 waterproof and dustproof rating.

They effectively resist rain, road water, mud, and dust entering the motor, helping prevent short circuits, Hall sensor damage, and moisture affecting the wind. They are suitable for outdoor driving in various weather conditions.

6. Universal non-destructive installation

The axle diameter, mounting width, and mounting holes of the dual-motor kit are compatible with more than 95% of low-speed four-wheel dual-drive vehicles on the market. The original vehicle wiring, brakes, and wheel assemblies can be directly adapted without modifying the frame.

This Dual-Drive Electric Vehicle Hub Motor supports upgrading old single-drive vehicles to dual drive and replacing existing dual-drive motors without major modifications. Voltage options include 48V/60V/72V, with multiple power combinations, axle lengths, and cable lengths available for customization. OEM bulk supply for complete vehicles is also supported.

Installation Precautions

1. Before installation, always disconnect the main vehicle battery power supply to prevent short circuits that could damage the Hall sensors and dual drive controller;

2. The left and right motors must have exactly matching specifications. Do not mix motors with different power ratings or voltage ratings, as this may cause power imbalance and deviation.

3. The system must be matched with a dedicated dual-drive electronic differential controller. Ordinary single-drive controllers cannot support coordinated operation of two motors.

4. Connect the phase wires and Hall wires strictly according to their corresponding colors. Ensure that the wiring of both motors is consistent to prevent uneven speeds and power differences.

5. After installation, center the wheel assemblies and securely tighten the axle nuts. First perform a low-speed no-load test of steering, acceleration, and motor operation. Only carry passengers or cargo after confirming there are no abnormal noises or jerking.

6. The motors are protected against normal rain and water splashes. Do not immerse them in deep water for extended periods or use high-pressure water directly on the sealing areas.

FAQ

Q: What is the difference between dual-drive motors and ordinary single-drive motors? What are the advantages?

A: A single-drive system uses one motor to provide power at a single point. Under heavy loads, on slopes, or on wet and slippery roads, it is more likely to slip, lack power, or overheat due to excessive motor load. A dual-drive system uses two motors working together with an electronic differential system, providing greater power, distributed load, better anti-slip performance, and stronger terrain capability. It is an ideal upgrade for mountainous areas, heavy loads, and muddy road conditions.

Q: Do both dual-drive motors need to be replaced as a pair? Can I replace only one motor?

A: They must be replaced as a pair. Dual-drive systems require highly consistent motor parameters. Replacing only one side or using motors with different power, voltage, or other specifications may cause vehicle deviation, jerky turning, tire wear, power imbalance, and increased power consumption, seriously affecting driving safety and motor life.

Q: Can an ordinary single-drive controller operate dual-drive motors?

A: No. Ordinary single-drive controllers do not have electronic differential control and cannot intelligently distribute the speed between two motors. A dedicated dual-drive electronic differential controller is required to achieve synchronized straight-line driving, differential turning, and smooth operation.

Q: Will a dual-drive system consume more electricity than a single-drive system?

A: Under light-load operation on flat roads, power consumption is generally similar to that of a single-drive system. Under heavy-load and hill-climbing conditions, the dual-drive system can be more energy-efficient. The load-sharing design keeps both motors operating within a more efficient range, avoiding the high losses and heat caused by overloading a single motor. This results in more stable range under heavy-load conditions.

Q: How should I choose the power combination for a dual-drive system?

A: For regular household use on flat roads: 500W–800W per side; for daily use with multiple passengers and light cargo: 1000W per side; for mountainous areas, frequent slopes, heavy loads, and commercial operation: 1200W–1500W per side. The 72V version provides greater power reserves.

Q: What causes jerky turning, dragging, or tire wear on a dual-drive vehicle?

A: In 90% of cases, there are three main causes: ① using an ordinary single-drive controller without electronic differential functionality; ② inconsistent motor specifications or mixing old and new motors; ③ inconsistent wiring or loose connections. Replacing the controller with a dedicated differential controller and using a matched pair of motors can effectively solve these problems.

Q: Do dual-drive motors require regular maintenance?

A: They are designed for maintenance-free operation. There are no gears, chains, or mechanical differential components, so no oil changes or chain adjustments are required. Daily maintenance only involves checking whether the axle nuts are loose, whether the wiring is damaged, and whether the connectors have been exposed to water. With proper use, the system has a very low failure rate.
