Energy Efficient Operation of Permanent Magnet Synchronous Machines Powering A Railway Electric Vehicle Breban S, Drancă M, Fărtan M

Abstract

This study aims to determine the losses of a permanent magnet synchronous machine used for propulsion of a railway electric vehicle in no-load and low-power operation conditions, found during vehicle coasting and low acceleration/deceleration speed profile. The simulation results are showing that it would be preferable to operate the electric machine at low power instead cutting the power from inverter.

Keywords railway electric vehicle, reference power distribution, direct drive system, no load operation losses.
