Experimental and numerical investigation of electric erosion in automotive motor bearings

<p dir="ltr">Electric Vehicles (EVs) are part of the solution to reach the 2050 net zero emission target. Trends towards higher voltage motors will likely contribute to an increase in electrically-induced failures in the bearings of EV motors. Electric motors prematurely fail from the passage of induced current in the bearings, a phenomena known as electric erosion . Determining the nature and conditions affecting these failures is key to mitigating their effects and ensuring that EVs continue to be a reliable mode of transport.</p><p dir="ltr">Presented at Leeds-Lyon Symposium on Tribology, Leeds, 5 – 7 September 2023,</p>
