Designing a permanent magnet synchronous generator for small water fall hydroelectric power plants

In this study, a radial flux generator which is driven directly for low speed turbines and structured by permanent magnets has been designed and analyzed by finite elements methods. The designed generator has got the good results which shows high performance characteristics of a permanent magnet generator. Both electrical and magnetic parameters of the designed generator have been calculated; the data obtained from the analyses have been commented. Maximum efficiency has been got by interfering to structure of generator regarding to magnetic materials saturation. Comparison results made have been demonstrated that the designed generator has superior performance rather than normal generator. In this condition, according to comparison results, radial flux permanent magnet machines are more useful and have higher performance than axial flux permanent magnet machines.
