Abstract: Demand on permanent magnets increasing rapidly due to greater developments on wind energy, computer hard drives, hybrid electric vehicles, air craft, and mobile phones etc. Nd2Fe14B is one of the promising permanent magnets to achieve efficient performance in many applications as compared to other magnetic materials. Unfortunately, Nd2Fe14B is considered as rare earth magnets which are difficult to get rare earth elements. It will be available only in few countries, but these are having lots of legal issues. The rare earth elements increase the cost of high performance of permanent magnets and its applications. Hence, making of rare earth free permanent magnets with large energy product is still considered as challenging task. Two phase magnets have achieved a great attention to researchers in the past two decades due to its high value of magnetic energy products and its good magnetic behaviour. By mixing Nd2Fe14B as hard phase permanent magnets and α-Fe as soft phase, efficient applications can be developed at low cost without compromising its magnetic properties. In this paper, the finite element model with multilayer structure of alternating soft and hard magnetic layers was built to simulate the performance of exchange magnets using ANSYS. The structural modelling of Nd2Fe14B and α-Fe is done separately, and the individual magnetic flux properties are being determined. Then properties of composite magnets were also investigated. The effect of volume fraction and thickness of soft phase magnets was analyzed to find the optimum value of coercivity and magnetic energy. Our simulation results shows that Nd2Fe14B/α-Fe has excellent magnetic properties and suitable for various practical applications. The results obtained in simulation open new way to optimize the performance of permanent magnets. The economic analysis of the PMSG is carried out as part of this work.
