A Design of Coreless Permanent Magnet Axial Flux Generator for Low Speed Wind Turbine

A novel axial flux permanent magnet generator for wind turbines

This paper presents the development of a framework used to optimize and experimentally validate a novel axial flux direct-drive (DD) permanent magnet generator (PMG) for the offshore wind turbine market. This technology aims to offer significant levelized cost of energy (LCoE) reductions via capital expenditure and operating expense (CAPEX and OPEX) savings – a key objective for the offshore in...

Designing a Coreless High-Speed Axial-Flux PM Generator for Microturbines

Multiobjective Optimal Design of an Axial Flux Permanent Magnet Generator for Directly Coupled Wind Turbines

Factors such as high efficiency, high power density, the possibility of realizing a compact multistage machine and the feasibility of applying a large number of poles make the Axial Flux Permanent Magnet (AFPM) generators highly appealing for use as low speed wind power generators. This study puts forth a multi-objective optimization of the efficiency and power density of a low speed AFPM synch...

Design and analysis of Axial Flux Permanent Magnet Generator for Direct-Driven Wind Turbines

Abstract: Axial flux permanent magnet generator (AFPMG) is can have one or two sided stator windings, meaning that the rotor disc of which the permanent magnet (PM) are mounted may be sandwiched in between two parallel stator discs. This paper deals with the development of AFPMG for a gearless wind energy system. This gives the axial air gap PM generator the potential for very high torque gener...

Analysis and Design of a Permanent-Magnet Outer-Rotor Synchronous Generator for a Direct-Drive Vertical-Axis Wind Turbine

In Permanent-Magnet Synchronous Generators (PMSGs) the reduction of cogging torque is one of the most important problems in their performance and evaluation. In this paper, at first, a direct-drive vertical-axis wind turbine is chosen. According to its nominal value operational point, necessary parameters for the generator is extracted. Due to an analytical method, four generators with differen...
