Electromagnetic Design and Thermal Analysis of Totally Enclosed Air Over Cooled Permanent Magnet Synchronous Motor for High-Speed Railway Distributed Traction

A totally enclosed air over (TEAO) permanent magnet synchronous motor (PMSM) for the distributed traction (DT) application of high-speed train (HST) is developed in this work. A study on the usefulness of the DT-HST is performed first. Considering the design requirement, electromagnetic and thermal models of the proposed traction motor are developed to check the operation under different operating conditions such as the machine rated power ratings. Based on the simulation model a prototype is developed and validated against the simulation result.
