Heavy Traction Systems – How to Model an Alternator

Overview

Alternators are core components in heavy traction systems, where robust performance and reliable power generation are critical. Accurate modeling of alternators is essential for system-level design, performance prediction, and control strategy development, especially in demanding applications such as rail, marine, and off-highway vehicles.​

This session provides a focused guide on how to model an alternator for heavy traction environments using Ansys simulation. We’ll discuss techniques for coupling electromagnetic results with thermal and mechanical models to ensure durability and performance under continuous or cyclic loading. The webinar concludes with a case study of a high-power alternator model, demonstrating setup, validation against test data, and performance optimization. ​
