The Rise of Electric Vehicles

Around the world, government policy is driving significant investment and growth in electric vehicles as they produce zero tailpipe emissions and offer the added benefits of increased fuel efficiency and lower maintenance costs compared to conventional vehicles – when maintained properly.

A key element of a well-maintained electric vehicle is proper shaft grounding.


Proven Shaft Grounding Solutions

Inpro/Seal offers several cost-effective solutions designed to protect against EDM, increasing motor and vehicle reliability.

The Inpro/Seal CDR (Current Diverter Ring) effectively diverts harmful shaft currents away from the bearings, directing them to ground. This prevents extreme bearing damage which causes vibration, noise and vehicle breakdown. Its proven design provides long-lasting protection for difficult-to-access electric motor bearings, offers a variety of mounting configurations and material options to fit the complexity of the vehicle design, and performs in wet or dry environments without impacting longevity.

For severe-duty environments, the robust design of the Inpro/Seal MGS (Motor Grounding Seal) combines shaft grounding capabilities with Bearing Isolator technology to eliminate lubrication leakage and bearing contamination.


Inpro/Seal Shaft Grounding Solutions increase reliability across a wide range of commonly used electric vehicle motor configurations, including:

  • Permanent Magnet Synchronous Motors
  • Induction Motors
  • Switch Reluctance Motors

These solutions provide superior bearing protection on vehicles ranging from class 1 passenger electric vehicles to Class 8 Heavy Duty Commercial electric vehicles.
