Micropitting Accelerated Test for Tribo-Elements Silding Parts of EV

Accelerated Micropitting Testing for Electric Vehicle Gear Systems

This application note explains how the Rtec-Instruments MPT-3000 Micropitting Tester enables fast, precise evaluation of surface fatigue and wear in electric vehicle (EV) gearbox and transmission components. Using a three-roller contact configuration, the system reproduces realistic rolling and sliding conditions to study micropitting, pitting, and crack initiation under controlled slip ratios. With high load capacity and variable speed control the MPT-3000 provides accelerated micropitting testing for EV gear design, lubricant performance evaluation, and tribology research—helping engineers optimize durability, efficiency, and reliability in next-generation e-mobility drivetrains.
