    Conversion of squirrel cage induction motor into permanent magnet generator and its finite element analysis

    The global electrical energy consumption is rising and there is steady increase of the demand on power generation. So in addition to conventional power generation units, a large number of renewable energy units are being integrated into the power system. A wind electrical generation system is the most cost competitive of all the environmentally clean and safe renewable energy sources in world. A relatively simple and low cost method for making permanent magnet wind turbine electric generators from burnt out squirrel cage induction motor, has been described in this thesis. Different types of generators used in wind turbines and general properties sought in a wind turbine generator are discussed first, and then the procedure of how to make a workable, multi-magnets poles, permanent magnet generator, from burnt out ordinary squirrel cage induction motors easily available at through away prices in the junk markets, is described. Finally, the test results of a 746 W generator are developed using single magnet and double magnet. The cost and performance analyses are studied. The Finite Element Method is used to study the flux density and magnetic flux path, followed by the energy density of Neodymium Iron-Boron (NdFeB) magnets. Different designs are used to analyze the results using QUICK FIELD software.
