6. Abstract
: This paper provides thermal analysis results for an interior permanent magnet synchronous motor (IPMSM) for high-speed trains (HST), depending on the cooling structure. The design requirements (torque/speed curve) of IPMSM are suggested to achieve HST running performance up to 320km/h. In particular, the back electromotive-force (EMF), which is the voltage of IPMSM, is limited for high efficiency operation of HST. The characteristics of the designed IPMSM are analyzed to identify the satisfaction of the design requirements. Loss analysis of the designed IPMSM depending on the speed is conducted using thermal analysis and normalized loss considering the measured results (speed and power) of the existing HSP on a real operation line; these results are used to analyze the thermal characteristic of the designed IPMSMs. Finally, the three cooling structures of the IPMSM are compared in terms of cooling performance.
