Fat-Tire Electric Vehicle Motor

Designed specifically for use with fat tires, this Fat-Tire Electric Vehicle Motor is manufactured by the reliable factory, Qianjiang Motor. We hold ISO 9001 and CE certifications and offer OEM/ODM services as well as technical support tailored to specific requirements.

Product Features

1. Integrated Wide Hub Structure

The widened hub cavity design and reinforced hub wall thickness make it resistant to deformation when carrying two riders or a full load of storage. Precision dynamic balancing ensures that wide tires do not vibrate or drift at high speeds, making it suitable for the dedicated assembly structure of retro wide-tire mini-Harley-style electric vehicles.

2. High-Torque Tile-Shaped Magnets

High-grade neodymium iron boron tile-shaped magnetic steel provides abundant starting torque, allowing easy travel on residential slopes, underground parking garages, and rural dirt roads. Multiple power options from 800W–2000W are available, with a load capacity of over 150kg, making it suitable for daily commuting, street vending, and cargo transportation.

3. Precision Pure Copper Windings

Fully automated and neatly arranged winding technology uses high-purity oxygen-free thick enameled wire with an optimally designed slot fill factor, allowing motor efficiency to reach up to 88%. During long periods of continuous riding, the coil temperature rise remains low, reducing the risk of overheating and aging, while providing approximately a 12% improvement in range with the same battery.

4. Multi-Layer Sealing and Waterproof Protection

Three layers of protection, including silicone sealing gaskets on the end faces, high-strength skeleton oil seals, and waterproof cable locking nuts, provide IP54 dustproof and waterproof protection. It effectively prevents water pressure and motor damage caused by daily rain exposure, car washing, or parking outdoors in humid conditions.

5. High-Precision Hall Sensors

High-quality original Hall components provide precise phase matching for smooth and jerk-free low-speed starting. The brushless structure eliminates carbon brush wear and keeps overall operating noise low, providing a better retro riding experience. The Hall sensor wiring is resistant to vibration and is less likely to break.

6. Independent New Technology

This product features our company's independently developed new technology. A completely new aluminum axle is being used to replace the traditional iron axle, giving the entire vehicle a more premium appearance. It supports the wheelie function. In overseas markets, our company holds 80% of the market. Overseas customers have opened more than 10 sets of molds for tires, hubs, axles, and other components at our company.

Working Principle

Battery DC Power → The controller receives throttle/brake signals + motor Hall position signals → The controller converts DC power into three-phase AC power → The stator coils generate a rotating magnetic field → This drives the rotor and wheel to rotate, moving the vehicle forward.

During braking/coasting, the motor reverses to generate electricity, and the current is returned to the battery (energy recovery).

FAQ

Q: Can the Fat-Tire Electric Vehicle Motor be installed directly on my vehicle without modifications? Do I need to modify the frame?

A: Direct installation in the original position is possible without cutting or grinding the frame, provided that the size, disc brake/drum brake structure, swingarm spacing, and axle diameter are the same. Before placing an order, check three items: hub size (10/12/13 inches), brake type, and motor axle thickness. If you are unsure, you can take photos of the side of the original motor and axle end and send them to customer service to confirm compatibility.

Q: How should I choose between the torque version and the speed version? What is the difference?

A:

① Torque Version: Provides strong starting power and excellent climbing ability. It is the preferred choice for heavy loads, carrying passengers, climbing underground parking ramps, and food delivery. It has a moderate top speed and more stable range.

② Speed Version: Has a gentler start and a higher top speed, making it suitable for single-person commuting, users pursuing higher vehicle speed, and riding on flat roads.

For daily household use and carrying passengers, choose the torque version. For increased speed and commuting on flat roads, choose the speed version.

Q: How should the motor phase wires and Hall wires be connected? Will incorrect wiring burn out the motor?

A: The three thick phase wires can be connected without regard to color. Rotate the wheel until it operates smoothly without vibration. The thin Hall wires must be connected strictly according to their corresponding colors. Incorrect wiring alone will only cause reverse rotation, vibration, or failure to drive and will not burn out the motor itself. Be sure to disconnect the power before wiring.
