The amount of electric and electronic equipment in automobiles has grown continuously bringing generating requirements more in line with starting requirements, thereby increasing the appeal of combined starter/alternator (S/A) systems. As surface mounted permanent magnet machines achieve high torque and power densities, which are very attractive for S/A applications, this paper outlines the solutions adopted for the development of a direct-drive axial-flux PM (AFPM) S/A including design characteristics and experimental data taken from a 3 kW prototype. This machine topology, having a reduced axial length and low phase reactance, is particularly suited for S/A systems where reduced room along the engine shaft is available and low voltage drop in generating mode of operation is required. Moreover by using a Litz wire winding good efficiency is reached along the whole operating frequency range.
