Ironless Axial Flux Wind Turbine Motor with Two Cylindrical Magnet Rings
Résumé
An ironless axial flux wind turbine motor is presented in this paper. The aim of this paper is to propose a motor that can be manufactured from simple components: magnets, copper and plastic. The motor must be feasible even in remote areas where machining facilities are limited. The winding and mechanical supports are sized from the magnets. The motor is therefore designed to be simple to reproduce and affordable in terms of manufacturing costs. Two rows of magnets are used to improve the performance of the motor. During design, choices on dimensions were made with fast calculations of output performance using models developed specifically for ironless motors. The performance measured on the prototype is in perfect agreement with the finite element simulations and the proposed models.
