Multiscale Noise and Vibration models for a Switched Reluctance-based drivetrain for EV and HEV

Abstract

The recent growth in Electric and Hybrid Electric Vehicles has resulted in the increased use of electric motors in automotive vehicles. At the same time, the cost of materials (magnets) have also gone up multi-fold. This resulted in the increased use of switch reluctance motors for drivetrains and other auxilaries. They are inherently noisy and contribute to the NVH degradation of the vehicle. In this presentation we would address the modeling and analysis of SRM by integrating EM solutions like JMAG with Vibration & Acoustic solutions like LMS/Virtual.Lab.
