The Design and Magnetic Analysis of MultiDisc and Layer Winding Toroidal Axial Flux Permanent Magnet Open Slotted (MLTAFPMOS) Synchronous Alternator

Abstract

In this study, a new multidisc and layer windingtoroidal axial flux permanent magnet open slotted(MLTAFPMOS) synchronous alternators are designed andmagnetic analysis was performed. Axial flux (AF) alternators area very good candidate for wind turbine applications. However,one of the disadvantages AF alternators is to increase AFalternator diameter with AF alternator power. The junctionpoints of AF alternator rotor shaft and disc have a very hugetorques via occurring from inner rotor diameter forces to outerrotor diameter forces. Therefore mechanically problems emergewith increasing alternator powers. The ideal solution for thissituation is to use a multidisc structure. In this study, a multidiscdesign for LTAFPMOS synchronous alternator was developed. A3d solid model of the developed design was obtained. Thenmagnetic analyzes were performed via Maxwell. It is decided thatthe multidisc structure is ideal to increase the alternator power asa result of analyzes. In addition, forces at the junction points isdecreased via multidisc structures
