The comparison results demonstrate that the proposed model for the wind power generator exhibits number of advantages such as improved efficiency with variable speed operation, higher energy yield, lighter weight and better wind power utilization. The design is validated by comparing its performance with standard models of existing wind power generators. The main focus of this research is to improve efficiency of the wind power generation system by investigating electromagnetic and structural features of AFPM generator during its operation in wind turbine. This innovative design is implemented in MATLAB / Simulink environment using dynamic modelling techniques. This paper presents an innovative design of a low-speed modular, direct-drive axial flux permanent magnet (AFPM) generator with coreless stator and rotor for a wind turbine power generation system that is developed using mathematical and analytical methods. However, the use of PMSG is rapidly increasing because of advantages such as higher power density, better controllability and higher reliability. The commonly used are induction generator (IG), doubly-fed induction generator (DFIG), electrically excited synchronous generator (EESG) and permanent magnet synchronous generator (PMSG). Overall, the research result showed that the variation of air gap has significant effect on the machine characteristics.Īn optimal design of coreless direct-drive axial flux permanent magnet generator for wind turbineĭifferent types of generators are currently being used in wind power technology. Meanwhile, the MMF that was generated by AFPMG decreased around 22% at 50 Hz due to the reduction of magnetic flux induced on stator windings. Based on the experiment result, the increasing air gap also reduced the starting torque of the machine with 39.2 Nm for air gap 2 mm and this value decreased into 34.2 Nm when the air gap increased to 4 mm.
For air gap 2 mm, the maximum value of the flux density was 1.04 T while 0.73 T occured for air gap 4 mm. The increasing of air gap length reduces the air-gap flux density.

The analysis has been done for two different air gap lengths which were 2 mm and 4 mm using 2D FEMM 4.2 software at no load condition. The two dimensional finite element magnetic method has been deployed to model and simulated the characteristics of the machine which is based on the Maxwell equation. Effect of air gap length on the magnetic flux distribution, starting torque and MMF has been investigated. The effect of the air gap variation on the characteristic and performances of single rotor - single stator AFPMG has been described in this paper. The axial flux permanent magnet generator (AFPMG) has been widely used especially for electricity generation. Kasim, Muhammad Irasari, Pudji Hikmawan, M.
