Abstract

An axial flux permanent magnet machine, designed to operate as a generator in a small-scale wind-power applications, is described in this paper. The machine is realized by using consecrated stator winding with open slots and surface mounted permanent magnets on rotor disk. Such a novel generator structure is simple to construct and its performance is good; it offers sinusoidal back-emf waveform, low torque ripple and high efficiency. A 1.6 kW prototype machine is constructed and is installed to a pilot power plant. Design results as well as test result for the prototype machine are reported in this paper
