Wind energy, one of the renewable energy sources, is important for meeting the energy needs of rural areas remote from energy transmission lines. The most suitable candidate for small scale alternator is a permanent magnet alternator construction. In this paper, a radial flux permanent magnet alternator is proposed. The proposed alternator consists of iron core of asynchronous machine body. Because asynchronous machines are the most used electric machines in the industry, their production costs are very low. Therefore, it was aimed to reduce the production cost with the available facilities. However, it is aimed to design a permanent magnet synchronous alternator by taking a basic asynchronous machine iron core and to analyze and optimize the design by using the RMXPRT module of ANSYS Maxwell software which uses 3d finite element method. Thus, a permanent magnet radial flux synchronous (PMRFS) alternator with minimum production costs and maximum electrical performance for rural areas will be designed and production parameters will be obtained. The design will be based on the body size of the basic asynchronous motor considered. The analysis will be carried out according to the RMXPRT module of Maxwell program of ANSYS depending on the design parameters. The most important feature of RMXPRT module which reduces analysis time. The asynchronous motor body used in the design has 24 slotted structures. The designed PMRFS alternator was analyzed with 8 poles. The nominal speed is 750 rpm. The number of winding steps is specified as (1-4). The number of phases per slot is one. In each slot, 35 turns of 5 parallel arms are applied. The electrical and mechanical parameters of the PMRFS alternator for which design and magnetic analysis are performed have been obtained. It is seen that the production cost is the minimum from the obtained results. The designed PMRFS alternator is an important candidate for meeting the energy need for rural areas with low cost. However, analysis using PMRFS alternator with different power can be done by using basic asynchronous machine body structure.
