Hyundai Mobis, the Korean auto group's parts supplier, has developed a new modular electric powertrain that promises compatibility with a multitude of EV platforms. Boasting a 215-horsepower output, the all-in-one drive unit integrates the electric motor, inverter, and reduction gear into a single housing.
The new unit is the second integrated powertrain developed in-house by Hyundai Mobis, after a high-performance 320-horsepower version, and will be followed by a more cost-conscious, 160-horsepower version tailored for compact cars within the first half of this year.
What makes this new drive unit stand out from the crowd is Hyundai's approach to standardization and modular design. Instead of relying on external suppliers to design and manufacture internal components using their specific techniques, Mobis went for a system-level standardization approach.
In other words, the stator for the drive motor, the inverter, and the power module are interchangeable between the different powertrains, which lowers costs and speeds up manufacturing, according to the parts maker. Hyundai Mobis says it also improved the motor structure by integrating new cooling technology and more energy-efficient power semiconductors.
All of this results in an all-in-one drive unit that has a 16% higher specific power output compared to similar products from other manufacturers, all while the overall volume is nearly 20% lower. It's also worth noting that two motors can be fitted to an EV—one at the front and one at the rear—which effectively doubles the power output.
