Modeling of machine elements in electrified environments and influences on the service life of current-damaged rolling bearings

Machine elements in electric drivetrains with modern frequency converters and ever higher power densities are more frequently exposed to the passage of damaging current. How severe is this damage, and can it be calculated in advance? These questions and more will be addressed in this seminar.

The first step towards achieving the critical goal of avoiding harmful current flow is to be able to predict this damage using suitable calculation models. This seminar aims to present current calculation approaches to create an understanding for the integration of suitable models into your own calculation routines. The following topics will be covered:

Causes of current passage
Differentiation of damage types
Calculation of the electrical properties of machine elements
Influences on the electrical properties of machine elements
Influence of the passage of current on the operating life of rolling bearings
Limits of the calculation approaches
Presentation of current research areas to improve understanding/calculation

Target audience

Electric drive development engineers
R&D engineers in the field of electrical properties of machine elements
Other interested parties

Main topics

Electrical modeling of machine elements with a focus on rolling bearings and a brief discussion on gears
Effects of current passage on rolling bearing operating life

Objectives

To develop ab understanding in order to be able to set up your own electrical calculation models and create an awareness of when current passages in rolling bearings can be considered critical
