“…16,17 Joule losses in the windings together with iron losses in the stator core, and mechanical losses cause the temperature rise in the electric motor. 18 Electrical motor components such as permanent internal magnets, winding stator insulation and bearings degrade as the temperature rises. Should be kept in mind that the stator winding insulation and permanent magnets in the PMSM have temperature limit, 19 and temperature control below critical value is challenging.…”

“…Optimized numbers of cooling fins are placed at optimal distances on the PMSM housing. 18,24 Fluid thermal analysis was done to investigate the effectiveness of cooling and heat dissipation as the coolant air flows through the permanent magnet machine air gap (Figure 9). Thermal mapping and flow phenomenon were analyzed using 3-D computational fluid dynamics CFD software and code that is used in this project is Star CCM+ ver.…”

This paper gives a brief review of advanced cooling methods and applications to the permanent magnet synchronous motors (PMSMs), as well as investigates the cooling systems design problem for PMSM systems. Heat sources and losses together with analytical and practical analyses are described. Next, the temperature distribution and its influence on the PMSM is investigated using simulation results. The main part of the paper includes a review of the proposed cooling methods that will release the requirement of heat transfer of the PMSM. The finite element methods (FEM) are applied using the AnSys CFD software to obtain high accuracy thermal model of the PMSM system. The new developed forced air-cooling methods are given in details, which enable to effectively redistribute the temperature and heat transfer increasing the efficiency of the PMSM machine. Examples of CFD simulation are outlined to illustrate the effectiveness and benefits of the strategies developed.
