| Abstract |
This paper proposed a design technique to improve the electromotive force (EMF) of the switched flux permanent magnet (SFPM) generator by using the Multi-tooth technique. The simulations were carried out through 2-D finite element method. The configuration of stator pole and rotor pole as well as the number of electrical phases were modified based on the principle of Multi-tooth technique. The output characteristics of the proposed generator structure including the magnetic field distribution, phase flux linkage, EMF and cogging torque were characterized and were compared with those of the conventional SFPM generator. The symmetrical property of magnetic field distribution was firstly confirmed. Then, the results indicated that the proposed multi-tooth SFPM generator can produce 4% higher EMF than the conventional model at same rotational speed. The EMF waveform of the proposed structure was indicated better smoothness than that of conventional structure. Meanwhile, the cogging torque scale of the proposed structure was slightly improved from the conventional structure. From the results, it was obviously seen that the proposed multi-tooth SFPM generator requires only half volume of permanent magnet compared to the conventional structure, while indicating the better EMF scale. Therefore, the proposed multi-tooth SFPM generator can be valuable choice for manufacturing in the SFPM generator, this structure could significantly reduce the usage of a permanent magnet which usually dominates the overall cost of the generator fabrication. |
