Brushless Hub Motors Technology in New Energy Vehicles

In today’s automotive industry, the focus is shifting towards new energy vehicles (NEVs), and among the various driving technologies emerging, wheel hub motor technology stands out prominently. This innovative approach integrates driving, transmission, and braking components into the hub of the wheel, eliminating the need for traditional transmission elements like clutches and shafts. As a leading Chinese manufacturer specializing in electric motor cores, we delve into the significance and advantages of brushless hub motors in NEVs.

The Rise of Brushless Hub Motors

Unlike traditional motors, brushless hub motors do not use brushes and electronic commutations for operation. Instead, they utilize electronic controllers to switch the current direction in the motor windings, enabling the motor to rotate.

BLDC hub motors have garnered considerable attention due to their potential to revolutionize NEV propulsion systems. These motors find applications across a wide spectrum, including electric vehicles, bicycles, motorcycles, scooters, and more. 

Their appeal lies in the seamless integration of crucial functions within the wheel hub, offering numerous advantages over conventional propulsion systems.

Advantages of Brushless Hub Motors

Enhanced Efficiency and Reduced Energy Consumption

By eliminating intermediary components such as clutches and transmissions, brushless hub motors significantly enhance transmission efficiency. This efficiency boost translates into lower energy consumption, a critical factor in the context of electric cars. 

As the industry increasingly shifts towards electric propulsion, hub motors emerge as a viable primary driving force. Even in hybrid models, these motors supplement power during acceleration, resulting in up to 30% lower fuel consumption.

Moreover, brushless hub motors excel in energy regeneration during braking, recouping approximately 80% of braking energy to extend the vehicle’s range.

Integration and Lightweight Design

The integration of power, transmission, and braking functions within the wheel hub simplifies chassis structure and reduces overall vehicle weight. This streamlined design not only enhances space utilization within the vehicle but also contributes to improved performance and efficiency.

With a weight reduction of up to 30%, vehicles equipped with hub motors exhibit superior handling and energy efficiency.

Flexible Driving Experience

Brushless hub motors offer unparalleled flexibility in driving dynamics. Directly driving the wheels, these motors allow precise control of wheel speed and torque through advanced microcontroller units (MCUs).

This precision control ensures optimal performance across diverse driving conditions without the need for complex manual interventions. Whether navigating urban streets or tackling challenging terrain, brushless hub motors deliver a responsive and dynamic driving experience.

Direct Drive

 In many applications, brushless hub motors are directly mounted within wheels or other components, which simplifies the mechanical design and reduces the need for additional gears or transmission systems.


In conclusion, the emergence of brushless hub motor technology marks a significant milestone in the realm of automotive. With its seamless integration of driving, transmission, and braking functions within the wheel hub, this innovative propulsion system offers unparalleled efficiency and performance.

By eliminating traditional components like clutches and transmissions, brushless hub motors enhance energy efficiency, reduce vehicle weight, and streamline the driving experience. Moreover, their flexibility in adapting to diverse driving conditions ensures optimal performance and responsiveness.

How does a brushless DC motor for in-wheel work?

Brushless electric hub motors utilize a series of permanent magnets and electromagnetic coils to generate motion. When electric current flows through the coils, it creates a magnetic field that interacts with the magnets, causing the motor to rotate and drive the wheel.

What are the types of Hub motors?

Direct Drive Hub Motors: These motors directly integrate with the wheel hub, providing a direct mechanical connection. They are known for their simplicity and efficiency.

Geared Hub Motors: Geared hub motors incorporate a gearbox within the hub assembly to increase torque output. They are often more compact and lighter than direct-drive motors but may require more maintenance due to the additional moving parts.

Gearless Hub Motors: Also known as direct-drive hub motors, these motors lack a gearbox and provide direct drive to the wheel. They offer high efficiency and reliability but may be heavier and larger compared to geared hub motors.

In-Wheel Motors: These hub motors are integrated into the wheel assembly itself, offering a compact and space-saving design. They are commonly used in electric bicycles, scooters, and small electric vehicles.

Regenerative Hub Motors: Some hub motors support regenerative braking, allowing them to recover energy during braking and store it back into the battery for increased efficiency.

High-Speed Hub Motors: Designed for applications requiring high speeds, these motors are optimized for performance rather than torque.

Low-Speed High-Torque Hub Motors: These motors are designed to deliver high torque at low speeds, making them suitable for applications such as electric bicycles and scooters where initial acceleration is crucial.

What are the limitations of brushless hub motors?

Despite their advantages, brushless hub motors have limitations such as reduced torque compared to traditional internal combustion engines and limited compatibility with certain vehicle configurations. Additionally, they may require specialized infrastructure for charging and maintenance.

Are brushless hub motors suitable for off-road applications?

While brushless hub motors excel in urban environments, they may not be as well-suited for off-road applications due to limitations in torque output and ruggedness. However, advancements in technology are continually improving their capabilities for diverse terrains.
