PRODUCT NEWS
After a stint on the test rig, the proof of concept was deemed
successful, delivering top results. The next step is to perform a
real-world validation out on the road. The in-wheel motors will
require less space and be more energy-efficient, lighter and
less costly, making them an attractive option for a wide range of
vehicle models and potentially highly scalable. " DeepDrive has
developed an exciting vision for the electric drive of the future, "
said Virsik. " The Startup Garage allows us to experiment with
DeepDrive and work out what drives might look like in the generation
after next. "
DeepDrive is now collaborating with other manufacturers and
major suppliers as well, such as Continental. In 2024, their motor
concept was honored with the German Innovation
Award. " Collaborating with BMW gave us a
springboard really early on, " said Felix Pornbacher,
co-founder and co-CEO of DeepDrive. " It helped us
navigate the complex corporate world and meet and
exceed the rigorous standards of the automotive
industry. Our goal now is to get it integrated into a
production model. "
Collaborating with startups accelerates innovations
at the BMW Group.
The BMW Startup Garage operates as a venture
client, implementing groundbreaking technologies
developed by startups and enhancing the BMW
Group's capabilities in innovation, sustainability and
operational performance. The venture client model
was established in 2015, with BMW acting as a
customer and working closely with young companies
to develop their technologies. " The BMW Startup
Garage is an excellent opportunity to connect with
startups. We then carry on working with the best of
them, " said Virsik. " Startups are really important to us
because they think unconventionally and out-of-thebox.
They give us new perspectives. "
Among key characteristics of the motor are that it is a dual rotor,
radial flux machine designed for high torque and power density
with small iron losses and high material utilization. Noise emissions
and torque ripple are low. The winding concept is distributed
bar winding with slot filling factor above 80%, suitable for a
simple manufacturing process. It uses 50% less magnet material
and 80% less iron than a comparably-rated motor. A highly
efficient SiC inverter is integrated into the machine, featuring an
innovative topology with SiC mosfets. Currently, DeepDrive is
focused on perfecting its system while providing sample production
and testing. It aims to begin serial production in 2025.
