V-I characteristics of a coreless ironless electric generator in a closed-circuit mode for low wind density power generation

This research deals with removal of ironcore lamination in electric generator to eliminate cog torque. A confinement technique is proposed to confine and focus magnetic flux by introducing opposing permanent magnets arrangement. The generator was fabricated and experimentally validated to qualify it...
