The paper describes the effect of cooling media and temperature on 20 KW axial flux BLDC motor performance using numerical and experimental analysis. The motor is applied in electric car with initially as natural air cooling, and it is modified as liquid cooling. Numerical and experimental analysis shows that cooling temperature has significant effect on power and efficiency of motor. Lower cooling temperatures produce higher motor power and efficiency. Based on experimental investigation, maximum power of water cooled BLDC motor can generate power of 25 kW and 81.0 % efficiency, while air cooled motor produces lower power and efficiency of 19.1 kW and 65.0 % respectively. Comparative analysis of motor performance based on model and experiment were presented as well. Maximum motor power calculated by model is slightly higher than that measured by experiment. It can be explained that in modeling, the friction losses on the bearings are neglected, while in the experiment, the friction loss remains a variable that affects the motor power output.
