A Five Phase Axial Flux Permanent Magnet Generator for Wind Turbine Application

This project discusses the benefits of five-phase technology for Wind Turbine Application with Axial Flux Permanent Magnet BLDC Generator (AFPMG). The radial flux permanent magnet generator has a setback of very low speed applications because, of the presence of cogging torque. This can be overcome by using an axial flux permanent magnet generator which has no cogging torque and has more advantage than a radial flux generator. Investigations proved that the five-phase topology harnesses some specific and important benefits that are not provided by three-phase systems. The benefits include improved fault tolerance and reliability, and reduced voltage, torque ripple and size of DC link capacitor. These are general improvements that are sought after in many applications including renewable energy applications. The objective of the project is to design a five phase Axial Flux permanent magnet BLDC generator for 1000W at a wind speed of 9m/s. Performance analysis of Axial Flux permanent magnet is investigated. MATLAB/Simulink model for five phase rectifier and Generator model is discussed. Test results are also presented in this project
