In this study, a new multidisc and layer winding toroidal axial flux permanent magnet open slotted (MLTAFPMOS) synchronous alternators are designed and magnetic analysis was performed. Axial flux (AF) alternators are a very good candidate for wind turbine applications. However, one of the disadvantages AF alternators is to increase AF alternator diameter with AF alternator power. The junction points of AF alternator rotor shaft and disc have a very huge torques via occurring from inner rotor diameter forces to outer rotor diameter forces. Therefore mechanically problems emerge with increasing alternator powers. The ideal solution for this situation is to use a multidisc structure. In this study, a multidisc design for LTAFPMOS synchronous alternator was developed. A 3d solid model of the developed design was obtained. Then magnetic analyzes were performed via Maxwell. It is decided that the multidisc structure is ideal to increase the alternator power as a result of analyzes. In addition, forces at the junction points is decreased via multidisc structures.
