Optimization of Low-Speed Dual Rotor Axial Flux Generator Design Through Electromagnetic Modelling and Simulation

Chapter


Abstract


  • Dual Rotor Axial Flux Generator (DRAFG) is a permanent magnet axial flux generator commonly used for low-speed power generation using wind power. This generator can generate useful amount of voltage even under very low revolutions per minute (RPM). Our focus has been to develop a very simple disk type DRFAG to generate 100W with RPM of no more than 100. This limit is set so that the generator could be operated from an age-old ‘hit and miss’ engine which is nearly noiseless consuming only a very small amount of fuel. Our design when combined with an engine is predicted to be operated for 10 h with one litre of gasoline making it very appealing for sub-Saharan countries. We accomplished a design that can generate 140 W with 100 RPM using 12 coils with a rotor dimension of 40 cm. We optimized many crucial parameters in this design including the shoulder length of coil, the gap between magnets and the coil, the coil size compared to the magnet size and so on. Cedrat Flux 12.1 was used to compute 3D Finite Element Analysis and to perform the simulation. Our design has optimized all the parameters to realize a low cost and highly efficient device.
