Analysis of Cooling Characteristics of Permanent Magnet Synchronous Motor with Different Water Jacket Design Using Electromagnetic–Thermal Fluid Coupled Analysis and Design of Experiment

Electrical losses are converted into thermal energy in motors, which heats each component. It is a significant factor decreasing motor mechanical performance. In this paper, the cooling characteristics were analyzed according to design factors of water jacket investigate performance permanent magnet synchronous (PMSM). First, electrical generated PMSM calculated using electromagnetic finite element (FE) analysis. Secondly, 3D electromagnetic–thermal fluid coupled FE analysis was performed analyze temperature distribution inside by applying loss as heat source. Finally, statistically experiment (DOE) method. found that mass flow rate 0.02547 kg/s and six passes with one inlet two outlets could be considered optimum conditions terms maximum temperature.
