Designing of a Permanent Magnet and Directly Driven Synchronous Generator for Low Speed Turbines

Abstract

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 model has got the good results which show 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 tried to get by interfering to structure of generator regarding to magnetic materials saturation. Comparison results made in the study have been demonstrated that the designed permanent magnet radial flux generator has superior performance rather than normal generator.
