Abstract

Improved design of axial flux permanent magnet generator for small-scale wind turbine

Highlights

Axial flux permanent magnet (AFPM) machines are very similar to the radial flux machines
Axial flux machine output power is proportional to the third power of the outer diameter, whereas in radial flux machines, the output power is directly proportional to the square of the diameter
The purpose of this study was to design a generator with high power density suitable for small-scale wind turbine according to the intermittent nature of wind speed

Summary

Introduction

Axial flux permanent magnet (AFPM) machines are very similar to the radial flux machines Such machines have a stator and a rotor with the disc structure and the magnets are placed in such a way that the manufacturing flux is in line with the common axis of rotor and stator. These generators generally have relatively high power and torque density. Axial flux machine output power is proportional to the third power of the outer diameter, whereas in radial flux machines, the output power is directly proportional to the square of the diameter. This is one of the basic differences between axial flux and radial flux machines [1]
