Revolution in electric mobility: an innovative donut-shaped propulsor that integrates into the wheels
The electric mobility is undergoing a radical transformation thanks to a new and revolutionary motor in the shape of a donut that integrates directly into the wheels of the vehicles. This innovative design promises not only to significantly reduce the weight of the system but also production costs by 50%. With an impressive range of up to 857 hp of power and 4,300 Nm of torque, Donut Lab’s proposal redefines what is possible in terms of efficiency and performance in the electric vehicle industry.
The arrival of an electric motor shaped like a donut, which integrates directly into the wheels of the vehicles, promises to transform electric mobility by offering unprecedented power with an innovative design. This advance represents a significant reduction in weight and production costs, opening new possibilities for cars, motorcycles, and more. Donut Lab is leading this revolution, showing how a creative approach can tackle historical technical challenges such as unsprung mass.
A Game Changer in the Automotive Industry
The development of donut-shaped electric motors represents a milestone in the automotive sector. Designed by the company Donut Lab, these motors adapt to the structure of the tires, eliminating the need for traditional transmission systems. Weighing only 40 kilos, their production could be up to 50% cheaper than that of conventional motors, making them an economical and efficient solution for a wide range of vehicles.
Technical Features of the Motor
The 21-inch motor from Donut Lab for automotive vehicles is capable of providing 857 hp and 4,300 Nm of torque, an impressive feat given its compact size and weight. Furthermore, this technology is not limited to cars; there are also adapted versions for motorcycles, trucks, and drones. Each variant of the motor has been designed to maximize efficiency and responsiveness, standing out with a power-to-weight ratio superior to that of its competitors.
Eliminating Barriers: Unsprung Mass
Traditionally, unsprung mass has been a critical challenge in the design of motors integrated into the wheels. However, Mark Lehtimaki, CEO of Donut Lab, has explained how the power density achieved minimizes the impact of this mass, making the added weight practically insignificant. This technical advancement reflects a significant step towards the widespread implementation of wheel motors, positively impacting the design and production of electric vehicles.
Future and Potential Applications
The versatility of these donut-shaped motors will be reflected in their adoption by different industries. Beyond cars, these motors are expected to be used in drones and heavy vehicles, where weight reduction and increased payload are paramount. Additionally, companies like Verge Motorcycles are already implementing smaller versions of these motors, which could signal a paradigm shift in the world of electric motorcycles.
Economic and Sustainable Impact
The development of donut-shaped electric motors not only represents technological advancements but also significant economic and environmental benefits. The simplicity of design and the reduction of active materials used could save up to 50% in manufacturing costs compared to traditional electric motors. This, in turn, could make electric vehicles more accessible and accelerate the transition to more sustainable transportation.
A Promising Future for Electric Mobility
The ingenuity behind the donut-shaped motor design demonstrates how innovation can overcome existing technological limits, providing new opportunities to expand electric mobility. As more companies adopt this technology, we may see a wider acceptance of electric vehicles in various transportation areas, evidenced by improvements in efficiency and capabilities, as reflected in innovations from other iconic brands.

The electric revolution within the wheels
The arrival of an innovative donut-shaped motor represents a significant advance in electric mobility, projecting a more efficient and sustainable future for vehicles. With a design that integrates directly into the wheels, it eliminates the need for traditional transmission systems. This not only reduces the vehicle’s total weight but also simplifies its structure and decreases production costs by up to 50% compared to conventional electric motors.
These revolutionary technical features provide impressive performance figures. For example, the 21-inch motor offers up to 857 hp and 4,300 Nm of torque, making it one of the most powerful options available. The reduction of unsprung mass, historically a challenge in wheel motor design, has been achieved thanks to the high torque and power density, ensuring that the motor does not compromise vehicle performance.
Although the use of this motor in every wheel to achieve high power levels does not yet seem viable for conventional cars, substantial potential is expected in commercial applications such as electric trucks and heavy-duty vehicles. Similarly, its smaller versions are ideal for motorcycles and lightweight vehicles.
The widespread adoption of this motor could result in a considerable reduction in the use of active materials, lowering production costs. Companies that integrate this technology will be at the forefront, offering vehicles that are not only more accessible but also much more environmentally friendly.
Ultimately, by breaking the barriers of traditional mobility, this donut-shaped motor is changing the game, illuminating a path toward a future where technology will redefine how we move more sustainably and efficiently.
