EnglishIn order to study the problem of the high temperature reached by the end windings, caused by the high current in the armature windings of permanent magnet synchronous motors (PMSM), a 560kW gas and liquid cooling PMSM used for a compressor is analyzed. The heat source is obtained by a two-dimensional numerical analysis of the electromagnetic field. A three-dimensional fluid-solid coupling heat transfer model is established. Under the action of the cooling medium, one-quarter of the PMSM structure is numerically simulated. The temperature distribution of the 560kW PMSM is studied, including rotor rotation. The temperature distribution of the PMSM armature winding and the distribution of fluid around the winding under different inlet air flow speeds are analyzed. The calculated values of the end winding temperature at different currents are compared with the experimentally measured values. The rationality of the three-dimensional fluid-solid coupling heat transfer model and the correctness of the calculation method are verified. This paper provides both the analysis and the computation scheme of the fluid-solid heat transfer of the PMSM.
