India has enormous wind potential and average wind velocity is about 6 m/s, whereas the conventional wind turbine mechanism is operated at 7 m/s–12.5 m/s. It is necessary to design low speed wind energy conversion to harvest the electrical energy from wind. Mostly, Radial flux permanent magnet generator (RFPMG) is used for low speed wind turbine applications. This Conventional RFPMG has the drawbacks of low flux density and increase in weight due to large number of poles accommodation. In order to overcome the above setbacks, this paper proposes a double sided coreless axial flux permanent magnet generator (AFPMG) for low speed wind energy conversion applications. The Performance analysis of the proposed AFPMG is carried out through finite element method using ANSYS Maxwell software. Finally the performance of RFPMG and AFPMG is compared based on the flux linkage, flux density, induced emf, stator current, moving torque, cogging torque, Total Harmonic Distortion (THD), material consumption, losses and efficiency. It is evident from the results that AFPMG gives the better performance than RFPMG in all such aspects.

低速风力发电机应用的径向磁通和轴向磁通永磁发电机的性能分析

印度拥有巨大的风能，平均风速约为6 m / s，而传统的风力涡轮机运行速度为7 m / s–12.5 m / s。必须设计低速风能转换以从风中获取电能。通常，径向通量永磁发电机（RFPMG）用于低速风力涡轮机应用。这种传统的RFPMG的缺点是磁通量密度低，并且由于容纳大量磁极而导致重量增加。为了克服上述挫折，本文提出了一种用于低速风能转换应用的双面无芯轴向磁通永磁发电机（AFPMG）。拟议的AFPMG的性能分析是使用ANSYS Maxwell软件通过有限元方法进行的。最后，基于磁链，磁通密度，感应电动势，定子电流，运动转矩，齿槽转矩，总谐波失真（THD），材料消耗，损耗和效率，比较了RFPMG和AFPMG的性能。从结果可以明显看出，在所有这些方面，AFPMG的性能均优于RFPMG。
