Volsun at 2026 Global XEV Drive System Conference
|
Volsun presented electric drive safety protection solutions at the 2026 Global XEV Drive System Conference in Shanghai, with shaft grounding rings for VFD motor bearing protection among the booth highlights.

On June 23, the 6th Global XEV Drive System Technology and Industry Conference opened in Shanghai under the theme "Driving a New Era: From Scenario Integration to Value Transformation." Companies from electric drive, vehicle manufacturing, and key component sectors gathered to review trends in electrified mobility and system reliability.
Exhibition Overview
Volsun participated in the event to present electric drive safety protection solutions designed to support reliability, durability, and operational safety in modern drive systems. Discussions across the conference floor reflected a shift toward longer service life and verifiable field performance—not only peak performance metrics.
As electric drive systems operate under high-voltage insulation requirements, elevated temperatures, humidity, and vibration, material selection and electrical protection are increasingly treated as system-level decisions rather than isolated component choices.

Customer Engagement at Booth
At the Volsun booth, engineers and procurement teams from electric drive and vehicle-related industries reviewed protection options for motors operating with inverters, potting materials for thermal management, and insulation solutions for wire harnesses in demanding environments.
A recurring theme in visitor conversations was how protection strategies perform under real operating conditions—not only in laboratory tests. Many teams asked how material choices map to specific failure mechanisms seen in the field.



Product Highlights (Shaft Grounding Ring)
Among the protection topics discussed, Volsun shaft grounding rings (SGR) drew attention from teams addressing bearing current and electrical erosion in VFD-driven motors. Shaft grounding rings are commonly used to provide a controlled low-resistance path that can help reduce shaft voltage discharge through motor bearings.
For inverter-fed traction and industrial motor applications, shaft grounding is often reviewed alongside thermal management and harness insulation as part of a broader reliability plan. Volsun also discussed conductive brush and material options where application requirements call for a different contact approach.
Industry Applications Discussed
Visitor questions covered a range of electric drive use cases, including:
- EV and hybrid traction motors with high switching frequencies
- Industrial automation drives with continuous variable-speed duty
- Pump and compressor motors exposed to humidity and contamination
- Systems where bearing protection must be validated under field load
Thermal conductive potting compounds, silicone thermal interface materials, and high-temperature insulation sleeves were also discussed for teams managing heat and environmental stress in compact motor assemblies.

Conclusion
The 2026 Global XEV conference reinforced that electric drive competitiveness increasingly depends on verifiable reliability in real operating environments. Volsun will continue to develop shaft grounding ring and related protection solutions that can support VFD motor bearing protection, thermal management, and insulation needs for electric drive customers.
