Abstract

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.
