Low speed PM generator for direct-drive wind applications

摘要

The paper deals with the design, FEM analysis, and testing of a surface-mounting permanent magnet (PM) generator with an inner rotor for wind applications. The purpose of this work has been to build a PM generator with simple structure, good performances and very low cogging torque. The paper presents the main design aspects and the performance characteristics of a 5 kW, 120 rpm and some test results of the PM generator prototype. Good agreement between simulated and experimental results has been achieved.
