Donut Lab Unveils Its New Motor At CES 2025 That Fits Into The Wheels Of Electric Cars. With Weight Reduction Of Up To 50%, Extended Range, And Lower Manufacturing Costs, The Technology Promises Futuristic Designs And Greater Accessibility In The EV Market.

Electric vehicles are becoming increasingly popular, but innovation never stops. Donut Lab, an electric motor manufacturer, revealed at CES 2025 a technology that could transform EV design: a donut-shaped motor designed to be installed directly into the wheels. Let’s understand how this idea can change everything.

What Is The New Motor?

The name “donut” is not without reason. The motor, developed by Donut Lab, has a large hole in the center, allowing it to be fitted directly into the vehicle’s wheels. This innovation is not just aesthetic, but practical: by eliminating the need for a central motor in the chassis, the total weight of the vehicle is significantly reduced.

This motor is a second generation of Donut Lab’s technology, with an impressive 630 kW of power (845 horsepower) and 4,300 Nm of torque per unit. Weighing only 40 kg, it promises high performance with less impact on the vehicle’s overall weight. It eliminates traditional components like transmission systems and half-shafts, creating more internal comfort space.

Benefits Of The New Motor For Electric Vehicles

The new donut-shaped motor is installed directly into the wheels, eliminating the need for a central motor and components like the transmission and half-shafts. This makes the vehicle lighter, improves performance, and allows for greater range. Additionally, it frees up internal space for more comfortable and futuristic designs, making electric cars more efficient and accessible. — The new donut-shaped motor is installed directly into the wheels, eliminating the need for a central motor and components like the transmission and half-shafts.

It frees up internal space for more comfortable and futuristic designs, making electric cars more efficient and accessible.

Less weight means greater efficiency. In EVs, weight reduction is a crucial factor for increasing battery range. With the donut motor, vehicles can travel longer distances without needing to recharge as often.

With no motor occupying space in the chassis, manufacturers will have more freedom to create innovative designs. Imagine cars with wider seating areas, greater cargo capacity, or even completely new internal layouts. The future of EVs has never been more exciting.

The Impact On The Electric Vehicle Market

Donut Lab claims that the new motor is up to 50% cheaper to manufacture, thanks to the use of fewer parts. This could make EVs more accessible, attracting a larger audience and accelerating the transition to sustainable vehicles.

While traditional motors require various components to function, Donut Lab’s wheel motor simplifies the process. This not only reduces costs but also decreases maintenance complexity. However, this simplicity presents new challenges.

Unsprung Mass And Its Impact On Handling

Although the donut motor reduces the total weight of the vehicle, it adds mass to the wheels, which can affect handling and braking. This issue, known as unsprung mass, is a concern that Donut Lab and other companies need to address to ensure performance and safety.

Still in the testing phase, technologies like Donut Lab’s and initiatives from companies like BMW show that the race to enhance EVs is just beginning. Despite the challenges, the possibilities are promising, especially for those seeking more efficient and economical solutions.

Donut Lab’s donut-shaped motor is proof that innovation can come from simple and functional ideas. By reducing weight, increasing efficiency, and opening up space for creative designs, this technology has the potential to transform the electric vehicle industry. Despite the technical challenges, the future looks promising, and we are just beginning to explore the possibilities of this innovation. What do you think? The donut motor could be the key to the next automotive revolution?

Só achei 630 kW por unidade um valor absurdo, pois o carro passaria a ter 4 vezes isso de potência com 4 Donuts.
