This paper approaches the electromagnetic design and finite-element analysis of an axial-flux permanent-magnet (AFPM) synchronous generator for small-scale wind turbines. The study is conducted to find a good-performance and cost-effective electric generator topology for micro-wind power application. The proposed double-sided two-stators-one-rotor AFPM synchronous generator with non-overlapping concentrated...
The paper presents simulated and experimental results concerning some rectifying solutions used as AC/DC stage in grid connected Wind Energy Conversion Systems (WECSs), employing direct drive, axial flux, modular Permanent Magnet Synchronous Generators (PMSGs). The solutions are based on three-phase diode bridge rectifiers, configured to give 6-pulse and 12-pulse rectifiers.
An 5 kVA axial flux permanent magnet synchronous generator(AFPMSG), designed to operate in a small-scale wind-power applications, is described in this paper. The stator of the machine is realized by using SMC to form teeth combined with a strip punched laminated core and concentrated winding. Such a novel generator structure is simple to construct and its performance is good. It offers sinusoidal...
The inductance in a generator is an important parameter to determine the generator operating point. Synchronous inductance consists of magnetization and leakage inductance. In this paper, an analytic method, Quasi-3D, has been proposed to predict inductance in an axial flux permanent magnet slot less synchronous generator. Analytic calculation was done using MATLAB. Then analytical prediction was...
The purpose of this paper is to describe the design of a direct-drive, permanent magnet synchronous generator to be used in the addition of electrical generation capability to water-pumping windmills. A characterization of the existing turbine structure is given in order to determine the generator's nominal mechanical input parameters. Electric machine topologies currently used in wind energy conversion...
This paper presents a multiobjective optimization of the design of a 10 kW /130 rpm axial flux permanent magnet synchronous generator (AFPMSG) dedicated to wind energy application. Firstly, a coupled electromagnetic, thermal and mechanical models used in the design procedure of the AFPMSG are presented. Secondly, the developed genetic algorithm (GA) approach is presented in three parts: the basic...
