Finite Element Analysis of Free Energy Permanent Magnet Motor Using Solidworks and Finite Element Method Magnetics (FEMM) Software

These days, our environment is getting worse, and the emission of gas from non-renewable energy sources such as fossil fuel and coal is the main reason for the current environmental issue. Therefore, the development of new energy sources which is clean and non-polluted to the environment is getting more demand in our world today. Free energy sources such as magnet energy are adaptable in replacing non-renewable energy sources. A permanent magnetic generator is a free-energy instrument that gives off entirely free energy by using the energy stored in permanent magnets. Much research has been done in this area, but none of which precisely focused on the tradeoff of magnetic material in this application. Although plenty of different magnetic materials have been synthesized including nanomagnetic ones, it is not easy to select an optimal magnetic material for a certain technological application due to their properties confliction. In this study, a new design of free energy permanent magnet generator has been developed and significant simulations are being done by using Solidworks and Finite Element Method Magnetics (FEMM) software for simulation modeling in order to tradeoff among magnetic materials in terms of performance. Results show NdFeB 52 MGOe which are very strong magnets made from alloys of rare-earth elements offer an optimum performance of around 11,309.734 J per motor cell and 8 magnets of 28,696.92 size in mm3 for a disk of radius 20cm; however, they are so expensive and in limited supply. Alternatively, strong nanomagnetic materials have been synthesized to replace rare-earth-based magnets in different applications.
