| Abstract |
Flux-switching permanent magnet (FSPM) machines have attracted wide attention in many
rotating applications that require high-power density. In this research, we propose for the first
time a novel six-phase FSPM generator with a stator featuring a V-shaped flux-focusing magnet
arrangement. The design is targeted for low-speed wind power generation. To achieve the design
objectives as a wind generator, the highly comprehensive structural parameters, including the number
of rotor poles, split ratio, and rotor pole width, are designed and optimized using 2D finite-element
analysis. From findings, the optimal stator/rotor pole combination is discovered to be 12/19 for the
considered power and speed requirements. When compared to the initial structure, the optimized
structure of the V-shaped FSPM generator is found to produce a significant improvement in EMF,
cogging torque, electromagnetic torque, power, and efficiency. The power-generating performance
of the proposed FSPM generator is found to be outstanding when compared to the radial-flux PM
generators described in the literature. Therefore, the proposed V-shaped FSPM generator is capable of
being used for low-speed wind power generation. The machine configuration adjustment approach
presented in this work can also be utilized for the design of permanent magnet wind generators. |
