Electric Powertrain

Overview of our electric powertrain components

Multiple challenges in the e-powertrain area - E-mobility is taking off, and with it the requirements and standards surrounding the construction of electric vehicles. Electric powertrains, in particular, are a highly complex system of multiple individual components, and can be a true challenge for many materials. Shaft grounding, for example, has to work in an oily environment and safely dissipate interference currents up to the 100 MHz range. In addition, they also need to be easy to integrate without having to make major structural changes to the engine.

Schunk technologies for enhanced performance and safety in electric drives

Thermal management and self-lubricating carbon components

Thermal management needs to function reliably, especially when charging and discharging batteries in electric vehicles. The only way to achieve long battery service life is to ensure top-notch thermal performance. In addition, thermal runaway protection concepts are essential - in an area where everything is constantly getting smaller, lighter and more powerful. Furthermore, components of the e-powertrain, such as our bearings and reinforcing sleeves, need to be highly temperature and corrosion-resistant to aggressive media. However, we also aim to produce our products as precisely as possible, with optimized weight.

Soft magnetic components in the e-powertrain

Soft magnetic components also handle important functions in the electric powertrain. These components need to be suitable for manufacturing efficiently in large-scale series production, need to delivery high power and torque density, and take up as little space as possible. Schunk has the answer to all of these requirements – thanks to our many years of experience and extensive materials expertise.
