An article in Electronic Environment . 2017/2, is about the fundamental failure mechanisms (capacitive, inductive coupling and frame voltage) that cause EDM (Electric Discharge Machining aka Bearing Currents or Electric Erosion) in bearings. This article expands on the theme and shows why “The Simple Explanation”, The Mathematical Models and the Real World view on EDM differ, both in nature and in practical use. It also adds a couple of new insights that are becoming more and more valid with the widespread use of Frequency Inverters and loads with higher-than-normal capacitance to ground.
The importance . and amount of electronics and software (SW) used in heavy vehicles is growing for every year. In order to meet customer needs of sustainable and reliable transports, very high requirements of reliability and robustness are necessary. In this very demanding truck environment, traditional component testing needs to be complemented with on-board software diagnostics and broad data collection from connected vehicles. In this way, real and potential failures can be detected very early on large fleets also then failure rates are relatively low.
Accelerated life testing . is a valuable tool for determining or improving the quality of primarily electronic, electromechanical and mechanical systems and components.
