In this study, the cooling performance of the motor was analyzed according to the number and the length of the fins of the heat sink, and at the same time, the effect of forced convection on the cooling performance improvement by changing the air flow speed of the cooling fan was conducted. In order to find out the cooling performance in terms of turbulent kinetic energy, pressure, and temperature according to the number of heat sink fins, length of fins, and wind speed of the cooling fan, an aluminum heat sink was modeled according to the size of the motor. The heating value of the motor was calculated, and it was set to be the same under all analysis conditions. The turbulence model applied for numerical analysis in this study used the standard k-ε model. As a result, it was confirmed that the cooling effect of the heat sink increases as the air flow speed of the cooling fan, the number of fins, and the length of fins increase.
