Single-Shaft Hub Motor

Looking for a scooter single-shaft hub motor that climbs without losing speed? Qianjiang Motor builds 24V/36V/48V gear reduction hub motors from 250W to 500W, delivering 40% more torque, quiet operation, and IP54 protection.

Product Features

1. Dedicated Single-Sided Axle Design

The motor adopts a lightweight single-sided output-shaft design with only one drive shaft and one mounting point, eliminating the need to modify both sides of the vehicle frame and avoiding installation interference and insufficient space commonly found with double-sided motors.

It is compatible with most simple flatbed handcarts, folding transport carts, and small power-assistance carts on the market. With a low conversion threshold, even beginners can quickly complete installation and adjustment, significantly reducing assembly time and conversion costs.

2. Lightweight and Highly Compatible

Compared with traditional double-sided hub motors, the single-sided motor eliminates redundant structures, resulting in a more compact and lightweight body. This effectively reduces the overall weight of the handcart and minimizes unnecessary load, making the cart more flexible and easier to steer.

The structure is designed specifically for lightweight transport equipment, does not occupy space on both sides of the vehicle, and is suitable for narrow-passage operations and foldable storage handcarts.

3. High Torque at Low Speed

Equipped with a precision gear reduction system and customized magnets, the motor provides strong torque at low speeds, with smooth starting and no stalling. The rated load capacity can reach 150–250 kg, making it suitable for indoor flat surfaces, gentle slopes, low thresholds, and smooth factory roads.

The speed-control logic is optimized for the low-speed operation of handcarts, providing linear and stable power output while reducing sudden movement and motor overload during transportation.

4. Maintenance-Free with Low Operating Costs

The entire series uses brushless motor technology, eliminating carbon brush wear and dust contamination while providing extremely low operating noise. It is suitable for quiet environments such as shopping malls, hospitals, indoor warehouses, and office buildings.

The gearbox contains long-lasting sealed lubricating grease and requires no regular lubrication. The stable structure and low failure rate eliminate the need for regular maintenance and parts replacement, making it ideal for frequent daily lightweight transport operations.

5. Water- and Dust-Resistant

The entire motor adopts a fully enclosed sealing process and achieves an IP54 water- and dust-resistance rating. It can effectively withstand warehouse dust, slight ground water accumulation, normal humid environments, and minor oil contamination.

The thickened alloy hub housing is impact-resistant, deformation-resistant, and corrosion-resistant, while the precision hardened gear set provides excellent wear resistance and durability. It can operate reliably during daily transportation and short-distance outdoor operations, with a significantly longer service life than ordinary brushed single-sided motors.

FAQ

1. What is the difference between a single-shaft hub motor and a double-shaft hub motor? How should I choose?

The main difference is the structure and application. A single-sided motor has a single output shaft and single-sided mounting structure, making it simple to install, space-saving, and suitable for light loads (up to 250 kg), simple handcarts, and conventional indoor flat-surface transportation.

It offers better cost performance. A double-sided motor provides power output and secure mounting on both sides, with stronger load capacity and climbing performance, making it suitable for heavy loads of around 300 kg, frequent slope operation, and complex construction-site conditions.

For daily lightweight transportation and conversion projects, a single-sided motor is recommended. For heavy-duty industrial applications, a double-sided dual-drive motor is recommended.

2. What load capacity is suitable for a handcart using a single-shaft motor?

A standard 24V/250W single-sided motor is suitable for light loads of up to 100 kg on flat surfaces; a 36V/350W version is suitable for 150–200 kg of regular transportation; and the 48V/500W high-performance single-sided motor can support a maximum load of 250 kg.

Single-sided motors are designed primarily for lightweight and practical applications. Long-term overloading is not recommended, as it may lead to power reduction and motor overheating.

4. How are the waterproofing and durability of the single-shaft motor?

The entire series is equipped with IP54 water and dust protection. The fully enclosed housing can withstand normal dust, light rain, damp ground and water accumulation, and minor oil contamination, making it suitable for indoor and semi-outdoor operations.

The thickened alloy housing and hardened wear-resistant gears provide impact and wear resistance, while the brushless structure eliminates easily worn components. Under normal use, the motor has a very low failure rate and a significantly longer service life than ordinary brushed motors.

Long-term water immersion and direct high-pressure water-jet cleaning of the motor core are prohibited.

5. How well does the single-shaft motor perform on slopes? Is it suitable for slope operations?

The single-sided motor is primarily designed for flat surfaces and gentle slopes and is suitable for gradual slopes of up to 5°. It is sufficient for small warehouse ramps and indoor threshold transitions. It is not recommended for steep slopes or severely uneven construction-site conditions.

For frequent heavy-load operation on steep slopes, a double-sided drive motor is recommended for better power and stability.

6. Is the single-sided motor noisy? Is it suitable for indoor use?

It uses a brushless quiet motor core and precision noise-reduction gear set, eliminating the friction noise associated with traditional carbon brushes. It operates with very low noise, smooth performance, minimal vibration, and no dust pollution, making it well suited for hospitals, shopping malls, offices, indoor warehouses, and other indoor environments with strict noise and cleanliness requirements.

8. How should I choose between different voltage and power specifications?

For light indoor loads and short-distance, low-frequency use: 24V 250W is recommended for longer range and lower energy consumption. 

For daily general transportation and occasional gentle slopes: 36V 350W is recommended for a good balance of power and cost performance.

For frequent operation and full-load transportation: 48V 500W is recommended for stronger power and more stable operation.
