Performance and optimum characteristics by finite element analysis of a coreless ironless electric generator for low wind density power generation

Cogging is an attraction of magnetism between permanent magnets and soft ironcore lamination in a conventional electric ironcore generator. The presence of cog in the generator is seen somehow restricted the application of the generator in an application where low rotational torque is required. Cog...

Therefore, this research is embarked to study fundamentally about the possibility of removing ironcore lamination in an electric generator.
