This paper presents an inside-out axial-flux permanent-magnet synchronous motor optimized by genetic algorithm based sizing equation, finite element analysis and finite volume analysis. The preliminary design is a 2-pole-pair slotted TORUS AFPM motor. The designed motor comprises sinusoidal back-EMF waveform, maximum power density and the best heat removal. The GA attained the dimensions of the motors with the highest power density. Electromagnetic field analysis of the candidate motors from GA with various dimensions was then put through FEA in order to obtain the motor's characteristics. Based on the results from GA and FEA, new candidates were introduced and then put through FV A for thermal behavior evaluation of the motor designs. Simulation results show that the designed IkW motor satisfies the desired technical specifications while its highest temperature reaches to 87 degrees Celsius at the rated speed and the full load condition.
