Grounding device

Product overview
Automotive manufacturers face capacitive interference currents originating from rotor shafts in electric drives. These currents can cause bearing and gear damage as well as broadband radio interference. This shaft grounding assembly provides targeted protection against bearing damage while damping interference emitted from the shaft up to approximately 50 MHz.

You benefit from these advantages

• Schunk quality for future e‑mobility applications
• Precisely matched metal‑graphite contact material
• Effective prevention of bearing and gear damage and reduction of high‑frequency interference in electric vehicles
• Suitable for all vehicle electric drive units

Applications
Protection of bearings and gears in automotive electric drive units; damping of interference signals emitted from rotor shafts up to approx. 50 MHz.
