Abstract

This paper presents a novel permanent-magnet (PM) brushless machine for wind power generation. In this machine, an outer-rotor topology is engaged aiming at capturing wind power directly. In order to match the wind speed as well as produce electricity in a normal frequency, a conventional outerrotor generator usually has a bulky size with a very large pole number. The purpose of this paper is to artfully integrate a high-speed PM brushless generator with a coaxial magnetic gear to achieve high power density. By using finite element method (FEM), the static characteristics are analyzed. Computer simulation for no-load and full-load operation is also conducted based on time-stepping FEM. The results are given to verify the validity of the proposed machine.
