With the popularity of fuel cell technology rising, so too is the decision to use a brushless dc motor for fuel cell applications. Not only does a brushless motor remove the need for dc to ac inverters, the absence of brushes completely eliminates the risk of arcing or sparking. Compared to brush dc motors, these have a longer lifespan, and some would even consider them to be nearly maintenance-free. The motors also feature integrated electronic capability, wide dynamic speed range that reduces power consumption, and high efficiency.
A new method of modeling how they are created with chemical vapor deposition (CVD) could reduce the cost of carbon nanostructures used for for research and commercial applications, including advanced sensors and batteries.
BMW has already incorporated more than 10,000 3D-printed parts in the Rolls-Royce Phantom and intends to expand the use of 3D printing in its cars even more in the future. Meanwhile, Daimler has started using additive manufacturing for producing spare parts in Mercedes-Benz Trucks.
