    As global warming accelerates due to greenhouse gases, various industries are making significant efforts to reduce greenhouse gas emissions. The automotive industry is also following the environmental policies of developed countries to achieve carbon neutrality, including exhaust gas regulations. Especially, the transportation field the largest contributor to greenhouse gas emissions, accounting for 30% of total emissions. In this study, it deals with the effective heat management of eco-friendly vehicles such as electric cars and hydrogen vehicles. Hydrogen fuel cells generate electricity and water through the combination of hydrogen and oxygen, releasing a significant amount of heat in the process. For hydrogen fuel cell vehicles, managing this heat is necessary for the vehicle's durability, making research on thermal management systems essential. This paper compares and analyzes the performance characteristics of a 10kW fan motor used in the thermal management system of hydrogen fuel cell buses, based on different pole-slot combinations. The no-load and load performance of the 16-pole and 24-slot combination as well as the 20-pole and 24-slot combination were compared, focusing on various characteristics such as cogging torque, torque ripple, radial force, and efficiency. The results indicate that the 20-pole 24-slot combination exhibited superior performance in terms of cogging torque and torque ripple.
