Comparative design analysis of ferrite-permanent-magnet micro-wind turbine generators

Abstract

This paper investigates two topologies of ferrite-permanent-magnet synchronous machines for use as direct-driven generators in micro-wind power applications, i.e. the axial-flux double-sided inner-stator permanent-magnet (AF-PM) generator and the radial-flux spoke-type interior-permanent-magnet (RF-IPM) generator. The comparative design analysis of AF-PM and RF-IPM micro-wind generators based on finite-element field analysis proves that both topologies represent a good-performance and cost-effective solution of choice for micro-wind power applications.
