Donut Lab's main products are five motor models, ranging from a 3kW small motor for a drone to a 630kW high-performance electric motor for a supercar. A big feature of these motors is their hollow design, which resembles a donut, but don't be fooled by their lightweight appearance! For example, the flagship 630kW motor weighs only 40 kilograms but can provide 845 horsepower. By calculation, it has an impressive energy density of 15.75kW per kilogram, cementing their position as the leader in the global electric motor power density ranking.
In the past, we've seen electric motors from the UK's Equipmake that once held the "highest motor power density in the world," but they had to relinquish the spot due to the weight being doubled in actual mass production. But the data from Donut Lab doesn't seem to budge—at least in their presentation at CES, their product is definitely full of competition.
Aside from power density, Donut Lab is also gaining attention because of their amazing torque density. Their flagship motor can output up to 4,300Nm of torque, with 108Nm of torque density per kilogram, which is a benchmark that is hard to beat in the industry.
This "donut" design isn't just pretty to look at. The hollow design of the Donut Lab motor not only reduces the need for traditional drive systems hardware such as drive shafts, but also provides more space inside the vehicle. For example, in small electric vehicles, it can provide extra room for the passenger's feet! More importantly, the lightweight motor design will help reduce the effect of "unsprung mass" on vehicle performance, which is of great importance in optimizing overall vehicle performance.
Donut Lab's ambition isn't just about building a supercar. Their products have a wide range of applications from drones, robots, lunar rovers, and warships. They even plan to launch a complete electric power ecosystem, including battery packs and control software, to help users have customized electric solutions.
In the future, Donut Lab plans to expand their applications even further, and they have already started supplying for some mysterious first-release projects, including their support project for the all-terrain vehicle Oruga Unitrack. This product shows their endless potential in a futuristic design.
There is no definite price for the donut motor at the moment, but it is certain that the performance of this product has left an indelible mark on the industry. Maybe one day, your car will not only have a donut-like motor, but also provide a driving experience as fun as eating dessert!
