Design and analysis of multi-phase Permanent Magnet BLDC Generator for domestic wind turbine applications

This paper discusses the benefits of five phase technology for domestic wind turbine direct driven BLDC generators. The performances of five phase Radial Flux Permanent Magnet BLDC Generator (RFPMG) is discussed. Multi-phase technology harnesses some important benefits such as improved fault tolerance, reliability, reduced voltage and torque ripple. This paper also discusses the design of five phase RFPMG which was optimized to use in areas where wind speed is less. Finite element analysis and Matlab / Simulink are used in the investigations. Test results are also presented in this paper.
