Abstract:
This paper focuses on the thermal analysis of a Permanent Magnet Synchronous Motors (PMSMs), which are widely used in electric vehicles (EVs). During the operation of an EV over extended periods, PMSMs usually generates significant heat due to various motor losses, such as copper loss, iron loss, magnet loss, mechanical loss, and others. Moreover, different driving cycles yield different outcomes regarding hotspots and maximum temperatures. In the first stage of analysis, the World Motor Cycle Test Cycle (WMTC) driving cycle is applied to determine the motors operating points for the motor. This information is then used in the second stage of the thermal analysis, which reveals the concentration of losses in the motor and identifies temperature distribution, and the highest and lowest temperature locations in the motor under different housing designs. These designs include: Case 1 design with the variation of fin height, Case 2 design with the variations in number of fins, and fin length, and Case 3 design with the variation of internal fluid types, cooling circuit fluid types and flow rates to determine the heat distributions in the motor structure. Case 1 design shows that fin height at 30 mm has the lowest in-slot winding and end winding of 78.15 ˚C and 79.53 ˚C, respectively and maximum efficiency of 96.19%. Case 2 design shows that number of fins at 32 and the fin length of 220 mm has the lowest temperature in-slot winding and end winding of 78.96 ˚C and 80.33 ˚C, respectively and maximum efficiency of 96.19%. Case 3 shows that the design of using oil as internal fluid and water as cooling has the lowest in-slot winding and end winding of 35.92 ˚C and 32.05 ˚C, respectively and maximum efficiency of 96.27%. The results can be used to study motor efficiency and its effects on thermal performance during the design process
