Design and Simulation of an Axial Flux Permanent Magnet Generator for Low Power and Low Speed using Finite Elements

Axial fluxgenerators are machines used in wind power generation systems, therefore, this document presents an analysis of anaxial fluxpermanent magnet generator for low speed and low power. The proposedtopologyis a purelycoreless double rotor generator, withtrapezoidalwinding, with a Halbach matrix for permanent Neodymium magnets in order to eliminateiron in the rotor discs, and has 12 magneticpoles. The topology design and arrangement of the windings and magnets around the circumference of the disksisdescribed. 2D finiteelementanalysis in COMSOL software isused to simulate the proposedtopology, the resultsobtained show that the purelycorelesstopology has good performance and can beused for low power and low speed applications.
